2.13 Daughter Board Connection
The ACL-8216 can be connected with five different daughter boards,
ACLD-8125, ACLD-9137, 9182, 9185, and 9188. The functionality
and connections are specified as follows.
2.13.1 Connect with ACLD-8125
The ACLD-8125 has a 37-pin D-sub connector, which can connect
with ACL-8216 through 37-pin assemble cable. The most
outstanding feature of this daughter board is a CJC ( cold junction
compensation) circuit on board. You can directly connect the
thermocouple on the ACL-8125 board.
2.13.2 Connect with ACLD-9137
The ACLD-9137 is a direct connector for the card which is equipped
with 37-pin D-sub connector. This board provides a simple way for
connection. It is very suitable for the simple applications that do not
need complex signal condition before the A/D conversion is
performed.
2.13.3 Connect with ACLD-9182
The ACLD-9182 is a 16 channel isolated digital input board. This
board is connected with CN1 of ACL-8216 via 20-pin flat cable. The
