The C1032 is a single-width CAMAC module which is used as an interface between the control system, one SWIC Scanner, and its associated motor drive. It contains a 16-bit Z8002 microprocessor, 32k of RAM, 32K of EPROM, a Z8036 CIO, a 2681J DUART, a Tev clock event-decoder, an 032-style block-transfer circuit, two relays and optically-coupled inputs, and an ARCnet LAN interface. The above features allow the module to replace the 032/036, 091/096, and 014/154 modules required for typical SWIC Scanner support. In addition, a 2.5 Mbit ARCnet LAN is provided for high-speed transfers of Scanner data.
The C1032 is an updated application of the C1045 Motion Controller module. When developing the C1045, hardware considerations were made to allow for future support of SWIC Scanners. The module's I/O connector is pin-for-pin compatible with the 032. With the ability to decode Tev events, and two open-collector outputs (defined as START and CLEAR), timing for a Scanner can be generated on-board. Application-specific parameters can be downloaded to the module through CAMAC or ARCnet. Attempts have been made to emulate the 032 F-codes without compromising the performance capabilities built into the module. CAMAC 032 pseudo-emulation and unique F-codes are described later in this document.
The C1032 maintains a local data pool of SWIC Scanner information which allows it to respond to requests from CAMAC within 20 usec of a request. The data pool is updated as the data becomes available from the scanner. Data is unavailable from T5 until the updateing is complete.

2. Serial Link Interface
The 1-Mbit serial link is composed of two 64 deep, 8-bit FIFO's and two 50C32 EPLD's clocked at 20 MHz. The serial transmission packet is composed of a start bit, the low data byte, and the high data byte. Since the FIFO's are byte-wide, two read/write cycles are needed to move the 16-bit data to/from the serial link. Once a byte of data is available at the output of the TX FIFO, the transmit EPLD outputs a start bit and begins transmission. This means that both bytes of a word must be successively written to the TX FIFO without interruption. The TX circuit will not output data unless the TREQ input is asserted. When the RX FIFO becomes full, the RRDY line is de-asserted, stopping any further reception of serial data. Transmit and receive status lines are available for vectored interrupts (only receive interrupts presently supported).
3. RS 232 Interface
The Signetics 2681 Dual Asynchronous Transceiver (DUART) is configured by firmware for 8 data bits, 1 stop bit, no parity, 9600 baud, no CTS/RTS handshaking. The DUART generates a non-vectored interrupt when RX data is available. Since only the RS-232 transmit and receive signals are present, the X_ON/X_OFF protocol is supported in software. RS-232 signals are buffered with a MAX233 interface chip. Channel 1 is available at a front panel 4-pin LEMO connector. Both channels of RS 232 are present at the rear Viking connector. Both channel signals TBE (transmit buffer empty) and DAV (data available) are capable of generating vectored-interrupts (though currently not supported).
Output lines OP3-OP0 are used for status and control of the following information. OP2 and OP3 respectively provide software-generated IN/OUT status of the SWIC motor position. OP0 and OP1 are NOT direct status of the START/CLEAR outputs. The following table shows the allocated address space for the 2681 registers:

4. Z8036 CIO Counter/Timer
The Z8036 is a multi-function chip which provides system counters, status and vectored-interrupt handling. It has a total of 20 I/O lines available for control and status monitoring. These signal lines are described in more detail below. The PCLOCK input is a 5 MHz square wave. The Z8036 is initialized to the following settings upon reset and power on. CT1 is set up in a 1 KHz repetitive one-shot mode with interrupt vector #6H. CT1 triggers CT2, which then divides by 100 to get a 10 Hz interrupt rate on vector #2H. CT3 is available for use by applications programs. The following tables show the address space allocated to the Z8036 CIO Counter/Timer and PIO Unit.

bit 1 SERDY H = xmt fifo has data in it (status) (input)
bit 0 LANIRQ H = ARCnet IRQ (vec. 10H) (input)
5. TEV CLOCK DECODER
The Tev clock decoder circuit is capable of decoding any of 256 possible events. TCLK and TDATA are fed by P1 and P2 respectively from the CAMAC Dataway. A 256 x 1 bit (word boundary) RAM provides a decode-enable mask for each event. Writing a "1" to the desired event location enables that event. An EPM5032 EPLD detects and outputs a decoded event which forms an address for the RAM mask. If that particular address (event) contains a "1", an interrupt (16H) is generated, and the address (event) is loaded into a FIFO where it can be read out by the processor. A "read" of the FIFO clears the interrupt. Interrupts will be generated as long as the FIFO contains events.
6. TIMER INTERRUPTS
Timer CT3 is available for user applications. Timer CT1 interrupts every millisecond. The processor re-enables the interrupt and returns from the service routine. Timer CT2 is set to interrupt at a 100 Hz rate. The timer interrupt is used to perform several low-priority tasks:
1) increment the time of day clock
2) check for Tev events and update associated LED
3) output data from circular buffer to serial-link FIFO
4) do heart-beat LED
5) if either serial-link FIFO is full, set LAM
6) re-issue request for Scanner data if necessary
Any time the LAM source or mask register is changed through CAMAC, as well as every time the 100 Hz timer-interrupt occurs, LAM will be set or reset according to whether LAMEN is asserted and the contents of the source and mask registers.
7. CAMAC INTERFACE OPERATION
The CAMAC slave interface is implemented using a PROM for encoding the FNA code and generation of the "Q" response and a 50C32 EPLD providing sequencer control of the operation. The 50C32 outputs an encoded interrupt vector corresponding to the valid CAMAC operation that occurred. Invalid CAMAC operations are ignored, a "no Q" is returned to the Dataway, and no interrupt occurs.
CAMAC read functions always require at least two cycles before a "Q" is returned. This is because the processor cannot respond with the requested data in the 200 nsec required by the CAMAC Dataway protocol. An interrupt does not occur when "Q" is returned.
In the 032, when the F16 buffer is full, or the F0 buffer is empty, a "no Q" is returned for the respective operations. The 1032 differs from the 032 in that when all F0 data has been read out, a "Q" is still returned with data equal to zero. A "Q" is also returned for an F16 write even when the serial link TX buffer is full. Data is thrown away. When CAMAC requests Scanner data while the data pool is being updated, FF's are returned with "Q". Other quirks regarding CAMAC operations are discussed in the section on Scanner protocols.
The C1032 supports the full 24-bit Dataway. The lower 16 bits are on a word boundary (low byte = R/W 1-8, high byte = R/W 9-16). The topmost byte is also on a word boundary (low byte = don't care, high byte = R/W 17-24).
Current valid CAMAC operations are as follows:
CAMAC Functions ( see appendix C.1 )
7.1 CAMAC Timing Diagrams
This module conforms to the ANSI 583 1982 spec. for Dataway cycle timing as described in the standard and as shown in figures 9 and 10 on page 54.
8. C1032 to SWIC Scanner Protocol
The C1032 module communicates with the SWIC Scanner by sending it 16 bits at a time. Data to be sent to the Scanner is kept in a circular buffer which is loaded by CAMAC, ARCnet, or by the TCLKINT interrupt routine at event T6. The circular buffer is examined and emptied to the TX FIFO during the 10 Hz interrupt service routine. Should the buffer become full, a bit in the LAM status register will be set.
The module uses the existing Scanner command and setup codes. Setup data is stored in NV ram on the c1032 board. When data byte 07 is written over camac this signals the code to stored this and the following data as setup data for the scanner. Upon future reboots this data is then loaded to the scanner.
If datapool request for SWIC data is active the data will be returned when ready or worst case after T6 goes inactive. If invalid data is returned by the Scanner, all data is thrown away and a new request is made until T6 goes inactive.
There are only three types of Scanner data requests currently supported: group 1 (scans 1-5), group 2 (scans 6-10), and test pattern data. The module requests group 1 and group 2 types. These requests are prioritized by the 1032 in the order above. This is important to note, as there is no header information describing the Scanner data being returned. The test pattern is read after each reboot. Camac request for the test pattern data will force and update by setting a flag. This update will happen along with the normal data update after the next T5 interrupt.
9. SWIC Scanner to C1032 Protocol
The SWIC Scanner communicates with the C1032 module by sending it two bytes of data at a time. The block of data being sent out corresponds to whatever request was first made. The data block continues to be sent until all data is transmitted. When group 1 request is successful, then the request for group 2 begins. The first transmitted byte of a block of data is the total byte count for that block. The total block length is determined by the number of scans that the Scanner was set up to do. A group of 5 scans is 494 bytes long. If no scans were done in a group, only a header containing the Scanner name is returned. If the total bytes received is greater than the maximum byte count, all further received data is ignored, and a new request is sent to the Scanner.
Routine SERINT handles the serial link data input. Presently, no interrupt occur after each two bytes of data received. The status is polled at a 1ms rate and if data is available then this data is read (upto 250 bytes/polling).
Returned data from the serial link is stored in one of three 512-byte pages of ARCnet RAM and mirrored in system ram. Before being stored, the bytes in the data word are exchanged to conform to Intel byte-ordering. Presently no in-module analysis is done on the received data. This data is in the correct order for transmitting via ARCnet. This is later done later as a background task.
10. SWIC MOTOR DRIVE INTERFACE
The C1032 provides two relays, each with NO and NC contacts available for controlling a SWIC motor drive. This permits flexible interfacing to existing 154 or 014 type drive devices. Active-low isolated status inputs and common are provided for the "in" and "out" limit positions. These inputs are optically-coupled to the CIO. An on-board isolated VCC supply (40mA max.) provides active pull-up to the receiver LEDs. Motor "in" and "out" status LEDs are driven by the OP2 and OP3 lines of the 2681 DUART respectively, which is controlled by software.
11. BROADCAST DATA LINK (LAN)
This data link (ARCnet) is capable of supporting up to 255 nodes. The network supports a length limit of not less than one mile. Nodes are able to interconnect by way of a single coax cable running from node to node. ARCnet uses a token-based protocol and will employ a VME Bridge to connect the Intrahouse LAN to the Interhouse network.
The C1032 uses the a highly-integrated IC released by Standard Microsystems, the COM20020. Details of the ARCnet controller can be found in the COM20020 specifications, but a brief description follows. The ARCnet controller accesses an internal dual-ported 2Kx8 RAM organized as four 512-byte pages. A GAL20V8 provides signal translation between the COM chip and the processor for access to the RAM and COM registers, which are mapped as eight sequential registers beginning at location F701H. RAM is accessed by setting a pointer register to the desired address. An auto-increment feature allows sequential byte-wide accesses without the processor having to increment the pointer register.
The network connects to the C1032 via a ground-isolated front panel LEMO connector which must be adapted to RG-59 coax. Each ARCnet node must have its own unique address. The 8-bit ARCnet node address is software-selectable. When enabled, the COM20020 will generate interrupt LANIRQ* (vector 10H) to indicate the receipt of a message or the completion of a transmission. The COM chip passes and receives tokens transparently to the processor. When a token is received, the COM chip is allowed to transmit messages.
Re-configuration is also transparent to the processor. If the COM chip has undergone re-configuration, it will set a bit in the LAN status register (FC00H). The re-configuration and response times are software-selectable. An ARCnet hybrid contains the discrete cable-interface logic. The hybrid is transformer-coupled to the network and is protected from cable transients by an RC network.

As noted above, all accesses to the COM registers and RAM are made on odd address boundaries.
Address range F780-F7FF is mapped to an 8-bit latch into which the current ARCnet Node Address is written (odd byte only). The address needs to be written during system initialization or after any change is made to the ARCnet Address.
12. BACKGROUND DEBUGGER

16. MECHANICAL SPECIFICATIONS
This module complies with ANSI Std 583 1982 Mechanical specs. as shown in Fig.4 page 48 and Fig.8, page 53.
16.1 Typical CAMAC Dataway Connector
As described in Fig K4.2.2 of ANSI Std 583 1982 page 16.
16.2 CAMAC Board Specifications
16.3 CAMAC Board Layout
The parts selected fit on a single-wide CAMAC module. The CAMAC board has 6.57in x 11in (72 sq. in.) of usable space. The P.C. card is a 6-layer board composed of separate power and ground layers with four signal layers.
17. ELECTRICAL SPECIFICATIONS
17.1 CAMAC Dataway
This module complies with all the CAMAC signal requirements as specified in the ANSI Std 583 1982, page 39, Table 6, and all specifications as stated in the standard under section 7, Signal Standards.
17.2 Power Requirements
This module conforms to ANSI Std 583 1982 as stated in section 8, Power line standards. This board uses +/- 6v CAMAC power connections and is fused at 4A for +6v, and 1A for -6v. The input power connections have bypass capacitors and tranzorbs for transient protection. Pico-fuses provide protection against damage to the printed circuit board in the event of component failure or improper installation.
A preliminary initialization program can be examined by referring to Warner::USR$DISKS:[HDWDOCS.C1032.SOFT] files C32VXX.80K (XX==LATEST VERSION NUMBER).
The C1032 module should have jumpers configured according to previously described specifications. While the C1032 is compatible with existing 032 I/O connector wiring harnesses, it is best to also install a new wiring harness that includes the START and CLEAR signals.
The front panel ARCnet LEMO connector does not require connection to a network for the module to function properly. After turning on the power, the +/- Vcc LEDs should be lit, indicating that the fuses are intact and there is power to the module. At this time, the module should also have reset itself and performed it's initialization routines. The heart-beat LED should be blinking.
