hello forum, i don't see these zelio sr2/sr3 programmable relays mentioned much around the web but maybe someone has information about the (pn sr2 cbl01) data / programming cable? trying to find out : the cable pin-out, and/or is this purely a passive rs-232 cable or is there some level shifting done inside the plastic zelio end connector before it goes to the 6 pin pcb socket?, and lastly, are there any plc forums or groups that discuss these units on the web? thanx in advance for any possible help. bob gadget
