Solution:

I think the PCI-1751 is no problem to drive those relays on PCLD-885. However, due to the different type connector, the key point is the wire connection between ADAM-3968 and ADAM-3950, and the +12V power supply for PCLD-885. I don't know the customer's wire connection, following information just for your reference. ADAM-3968 (SCSI-II connector) ------ (SCSI-II cable) ------ (SCSI-II connector) PCI-1751 (Terminal Block : 1, 2, 3, 4, 5, 6, 7, 8, 9(GND), 10, 11, 12, 13, 14, 15, 16, 17, 18(GND)) | | | (Terminal Block : 47, 45, 43, 41, 39, 37, 35, 33, 50(GND), 31, 29, 27, 25, 23, 21, 19, 17, 50(GND)) ADAM-3950 (50 pin Flat Cable connector) ------ 50 pin Flat Cable ------ (CN2) PCLD-885 Using a external Power Supply to offering +5V and +12V to PCLD-885, because the PCI-1751 don't support +12V.
