GENERAL DESCRIPTION

The Bi Ra Model 5332 is a single-width CAMAC module with 32 differential front panel two-wire inputs. Connectors may be Type DC 37 or DD50P or S. Analog inputs are scanned and converted digital data stored in RAM. Data may be read without interrupting the scan. Channel scan rate is variable from approximately 200 to 750 . Removable analog return terminators and OVP diodes allow alteration of terminations and installation of capacitor mounted headers for single-pole input filters. A two-level multiplexer is followed by a high input impedance Programmable Gain Instrument amplifier, a Sample/Hold (SH) and a 12-bit ADC. ADC full- scale is strappable for unipolar +5V, +10V and bipolar 2.5V, 5V, and 10V. Straps allow data to be presented to the dataway as a 16-bit 2’s complement word. For bipolar, the sign is extended to 16 bits; bits 13 through 16 are zero for unipolar.

Individual channel gains may be any of nine from 1 through 1024 or set manually so all channel gains are identical. A scan Sequence register allows a sequential or random channel sequence to be scanned. The number of channels scanned are selectable in increments of 1 up to 32.

X is returned for all commands. Q is conditional.

FUNCTION CODES:

COMMAND	ACTION
(F0+F1)An	Read last converted Channel data from RAM for selected channel R1-R16, Gain R17-R20. R21-R24=0. Channels 0 through 15 read with respective F0 A0 throug Fo A15; channels 16 through 31 via F1 A0 through F1 A15. Q returned for valid data.
F2 A0	Read last converted data channel selected by sequence register. R1-R16 data, R17-R22 channel address. Advance sequence counter one count and start convert cycle on next channel at sequence counter address. Valid and Q for (RUN)(EOC).
F2 A1	Read converted data R1-R16 of channel R17-R22 selected by sequence register. Start new convert on same channel. Valid and Q for (RUN)(EOC).
F3 A0	Read sequence register R1-R5, Fault select R6-R10, R11=0, R12=1 if manual, 0 if Auto, Gain R13-R16 of channel R17-R21, Q returned and valid for (RUN)(EOC).
F5 A0	Read last converted data R1-R16 for channels R17-R21. Q if (RUN)(EOC)
F9 A0	Clear Sequence Register count to zero. Q if (RUN)(EOC)
F16 A0	Load Sequence Register W1-W5 and start conversion on selected channel with respective gain. Q for (RUN)(EOC) and valid.
F17 A0	Load Sequence Register W1-W5. Q if (RUN)(EOC) and valid.
F17 A1	Load RAM data. Channel W1-W5, Gain W6-W9 at address determine by Sequence Register. Advance Sequence Register address one count. Maximum Sequence Register address is determined by FAULT SELswitch seting. Q if (RUN)(EOC).
F24 A0	Disable RUN mode.
F26 A0	Enable RUN mode.
F27 A0	Test End-of-Convert(EOC). Q if (RUN)(EOC).
(Z+C)S2	Clear module Sequence Register to zero and Run FF.
