IoE1 serial processing node - technical overview
As the serial processing node for the Callisto series of remotes, the IoE1 carries four serial data ports, which may be physically presented as either RS-485 or RS-232 circuits. Two IoE1 ports may be linked for operation via an on-board Bell 202, 1200-baud modem. Of these ports, one may be optionally configured for operation over the dial-up network. Communications options supported include both synchronous and asynchronous, byte or bit oriented protocols. The IoE1 may be utilized for serial data exchange with master station(s), intelligent meters, relays, or other intelligent electronic devices (IEDs) distributed across the Callisto system. Like all Callisto boards, the IoE1 utilizes ArcNET technology and DAQ Voyager protocol to interface to the high speed LAN. Additionally, the industry standard Nucleus real-time, multi-tasking operating system allows for user-defined applications and algorithms to be easily incorporated into the unit.
