IoE2 communications processor - technical guide

The IoE2 is the 2nd generation Serial Processing Node for the Callisto series of remotes. It carries four serial data ports, and an IP Ethernet connection. Serial Ports may be physically presented as either RS-485 or RS-232 circuits. Communications options supported include both byte and bit oriented protocols. When used to replace or upgrade an IoE1, a Bell 202 modem may be plugged into port 1. The IoE2 may be utilized for serial data exchange with master station(s), intelligent meters, relays or other intelligent electronic devices (IED) distributed across the Callisto system.
