Pins 1 through 34 are the same with the exception that pins 8, 26, 28 and 30 are tri-state as opposed to open collector. This means that ytou'll need to connect 10 Kohm pull=up resisters from these pins to +5v. Pins 37 through 40 are ground +5v, ground and +12v respectively. This maps to a 'standard' power connector as 37-------------------- 2 (ground) 38-------------------- 4 (+5v) 39-------------------- 3 (ground) 40-------------------- 1 (+12v) I pulled this info from CIS a while back. It seems to work fine. Hope this helps. Barry King bking@ersys.edmonton.ab.ca Edmonton Remote Systems: Serving Northern Alberta since 1982
