Heres the deal, the latest and greatest in the gas pump world [Linked Image] is networking with Cat 5 back to the oil compaines POS network. There by allowing the gas pumps to continue accepting credit cards if the cash register goes down. My problem is conduits under the cabinet. I have one for AC, I have one for leak detection, can I use one for both the intercom and Cat 5 or do I have to have seperate pipes? You can mix voice and Data, why not data and intercom?? I have a call into the manufacturer, just wondered what you guys think. 4- 3/4 pipes to run a pump seems ridiculous to me. I could use shielded cables if interference is an issue?
