The one-wide CAMAC 202 module described is the 1 st generation Kluge. This module is used to monitor the readiness of remote devices and facilitate inhibiting Beam Sync. Clock transfer events. The C202 provides a summation of 150 GeV, 120 GeV and 8 GeV permits to the companion C289 module. Each C202 can support two remote locations with up to six devices at each location (twelve channels). Multiple C202 modules may be serially connected as needed. All connections are via custom I/O assembly.
Each of the two remote locations is connected via a six pair cable. For each pair the module separately sources fused (1/2 amp) +24 volt DC (provided by the CAMAC crate). The remote device is required to return the +24 volt reference signal for a permit state, typically by rrrelay contact closure. The return signal is attenuated and clipped to 4.7 volt at the C202 input. The maximum external series DC resistance should not exceed 2K ohm total.
Channels can be forced true by CAMAC command and/or jumper blocks on the PC board. Normally the mutually exclusive jumpers are selected so that inputs connected to active devices can be forced true by CAMAC command. Normally the mutually exclusive jumpers are selected so that inputs connected to non-active devices are forced true by non-volatile hard connection. The forced true status is readable by CAMAC command.
The state of the twelve inputs can be read by CAMAC command. TCLK $ED (failed request) will latch the state of the inputs. The permit output status, latch status and the +24 volt source fuse status for each channel can be read by CAMAC command.
One unique PAL is programmed in a matrix to select which inputs are combined to generate the permit outputs to the following C202 or C289.
There are only two C202 modules. They are unique because of the 20211 PAL and selected jumper options. These modules are intended to be installed only in Main Injector crate $94 slots 18 and 19 as labeled on the modules.
As of 28 Oct 99 the C202 in slot 19 has only the following active devices assigned::
As of 28 Oct 99 the C202 in slot 18 has only the following active devices assigned.
All input/output connections are via custom rear viking
connector cable assemblies.
