Table of Contents

^General Description

This single width module contains a 12-bit register for holding output data. Twelve relays, whose states are determined by the bits in the register, each supply an isolated normally open contact to the I/O connector. The relays may be energized and de-energized singly or in combination. The register can be written, cleared, set, selectably cleared, selectively set, and read. Individual bits may be set or cleared bia command subaddress.

^Interrupt Capability

A LAM flip flop is privided which, when enabled, may be set by a negative-going transition of an external input, by a command, or by a front panel switch. The LAM is cleared by direct command or by any command that affects the contents of the 12-bit register. Sequences of programmed outputs can thus respond to internal or external control.

^CAMAC Commands

C014 CAMAC Commands
F(0)A(0)Reads state (open/closed) of output relay contacts
F(6)A(0)Reads module number
F(8)A(0)Returns Q if LAM is set
F(9)A(0)Clears 12-bit register and clears LAM
F(10)A(0)Clears LAM
F(11)A(0)Presets 12-bit register and clears LAM
F(14)A(0)Sets LAM
F(16)A(0)Writes 12-bit register and clears LAM
F(20)A(0)Selectively clears 12-bit register and clears LAM
(e.g. a "1" to bit i (i=12..1) clears bit i only)
F(22)A(0)Selectively sets 12-bit register and clears LAM
(e.g. a "1" to bit i (i=12..1) sets bit i only)
F(24)A(0)Disables setting of the LAM flip flop
F(26)A(0)Enables setting of the LAM flip flop
F(28)A(11..0)Clears bit defined by subaddress and clears LAM. A(0) corresponds to output bit 1, A(1) to bit 2, etc.
F(30)A(11..0)Sets bit defined by subaddress and clears LAM. A(0) corresponds to output bit 1, A(1) to bit 2, etc.
C*S2Clears LAM and 12-bit register and disables LAM flip-flop
Z*S2Clears LAM and 12-bit register and disables LAM flip-flop

^Front Panel

The following lights and switches are provided on the front panel:
Module Select LightFlashes whenever module is addressed.
LAM Enable LightOn whenever LAM is enabled.
LAM LightOn whenever a LAM request is pending.
LAM SwitchSets LAM if LAM is enabled

^Modifications

In order to return X for valid CAMAC operations, the following modification is done:

  1. Cut ground trace from WW pin 1.
  2. Connect WW pin 1 to TT pins 9,10.
  3. Connect WW pin 2 to 6L.
