(1) Command is a word transfer from the 2132 to the HV4032A. Response is a word or block of words transferred from the
HV4032A to the 2132. It is always accompanied by one L2 (following the last word transferred if in a block).
(2) C = Channel address. CAMAC W16 to W11 for commands, R16 to R11 for responses.
X = Don't care. CAMAC W16 to W11 for commands, R16 to R11 for responses.
S = Switch, W11 (where W16 to W12 should be 0) for commands, R11 (where R16 to R12 are don't cares) for responses.
W11 or R11 equal to "1" is ON, equal to "0" is OFF.
M = Mainframe address, CAMAC W10 to W5 for commands, R10 to R5 for responses (addresses 0 to 63 possible for
HV4032, 0 to 16 must be used for the HV4032A, there should be no more than 16 mainframes per 2132).
V = Voltage, CAMAC W16 to W5 for commands, R16 to R5 for responses (0-4095 possible, HV4032A limits at 3300
for 3.3 kV pods and 3500 counts for 7 kV pods).
P = Pod type, 1 for 7 kV and 0 for 3.3 kV. Bit 2
0-15 = Tag (T), CAMAC W4 to W1 for commands, R4 to R1 for responses.
(3) HV must be OFF for command to be accepted.
(4) Expect 32 true voltages (actual rear panel output), channel 0 first, etc. with L2 on last (channel 32) data word only.
(5) Expect one T=9 word, no L2, for each failed channel in the module, followed by T=5 with an L2.
(6) Also can be transferred spontaneously at time of failure with an L2 and the high priority L1.
(7) Expect 32 demand values, channel 0 first, etc., with L2 on last data word only.
(8) Can be enabled or disabled by T=11 command.
(9) Status bits indicates:
0
2
= HV ON(1) / HV OFF(0)
1
2
= Calibrate(1) / Regulate(0)
2
2
= idle down(1) / Normal (0)

and 2
unused.
(10) Spontaneous transfer due to panic off or interlocking being asserted with L2 and the high priority L1.
(11) Failed channel responses are possible from channels 0 to 31. The 2 bit of C is set to indicate the initiator of a trip sequence.
(12) For 7 kV pods, the values entered and read through CAMAC correspond to the voltage or current according to: (CAMAC
voltage value) = (Actual/2); (CAMAC current value) = (Actual x8).
