IC-20 Network Controller

IC-20 Series Network Controllers

Accurate real-time data transmission for up to 99 remote data terminals over a radius of several miles is provided by one IC-20 wireless Network Controller. Data for each remote unit is individually buffered to provide flawless information transfer between the central unit and all the remotes.

Operating Information

Data is transferred synchronously over the radio link at 2400 or 4800 bps (depending upon model). Communication is over a single channel, so throughput depends on the length and frequency of messages for each remote unit. The PAD (Packet Assembly and Disassembly) interface provides full access to multiple portable units via the asynchronous RS-232 port, and the profile is configurable to match different types of terminal equipment.
