AD2B SEI to RS-232 Adapter (9-pin)
Descripción

The AD2B adapter allows the RS-485-like signal of SEI devices to interface to a standard RS-232 port (9-pin DB), such as those in IBM compatible PCs. The SEI (Serial Encoder Interface) bus is a simple, quick and convenient network of SEI devices interfacing to a RS-232 serial port. The SEI bus supports from 1 to 15 devices on a single 6-wire telephone-type cable, up to 1000 feet long.
