Note that incorrect setting of the ID byte DIP switches will cause
an incorrect module ID to be reported to the user in response to
a PDATAOUT command. All other module functionality is
unaffected by the setting of the ID byte switches.
Relay Bank
Configuration
If two banks of DC relays are to be used, various internal
jumpers must be installed. Examples of four possible
configurations are shown in Figures 4-3 through 4-6. The card is
shipped from the factory without any jumpers installed.
To access the jumpers, remove the right side cover from the
module. The jumpers are located on the large PCB Assembly.
There are two banks of relays. Each bank is configured
independently, and the two configurations do not have to match.
The banks are designated Bank A and Bank B.
Sink/Source
Configuration
A sink driver connects its output to ground to energize a load; a
source connects its output to B+ to energize a load. Eight push-
on jumpers are to be installed as shown below:
Bank A Source Driver:W5
Bank A Sink Driver: W6
Bank B Source Driver:W11
Bank B Sink Driver: W12
Power - Bank A
If an external supply is to be used, the jumpers at locations W3
and W4 are to be removed. If the VXI +5 V supply is to be used,
eight jumpers are to be installed at location W3 (1-2, 3-4, 5-6,
etc.). If the VXI +12 V supply is to be used, three jumpers are to
be installed at location W4 (1-2, 3-4, and 5-6). If the VXI +24 V
supply is to be used, the three jumpers are to be installed at
location W4 (11-12, 13-14, 15-16).
Power - Bank B
If an external supply is to be used, the jumpers at locations W8
and W9 are to be removed. If the VXI +5 V supply is to be used,
eight jumpers are to be installed at location W8 (1-2, 3-4, 5-6,
etc.). If the VXI +12 V supply is to be used, three jumpers are to
be installed at location W9 (1-2, 3-4, and 5-6). If the VXI +24 V
supply is to be used, three jumpers are to be installed at location
W9 (11-12, 13-14, 15-16).
