2.12 Daughter Board Connection
The PCI-9112 can be connected with five different daughter boards, ACLD-8125, 9137, 9138, 9182, 9185, and 9188. The functionality and connections are specified in the following sections.
The cPCI-9112 is equipped with 100 pin SCSI-II type connector, the DIN- 100S is a general purpose terminal board for connecting the external devices.
2.12.1 Connect with ACLD-8125
The ACLD-8125 has a 37-pin D-sub connector, which can connect with PCI-9112 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. The CJC only suitable for High Gain version board.
2.12.2 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.
2.12.3 Connect with ACLD-9182
The ACLD-9182 is a 16 channel isolated digital input board. This board is connected with CN1 of PCI-9112 via 20-pin flat cable. The advantage of board is a 500Vdc isolation voltage is provided, and it can protect your PC
system from damage when an abnormal input signal is occurred.
