RS-232C isolation and distribution amplifiers
The main purpose of the ES-250 and ES-251 are to improve the distribution capabilities of RS-232C or provide isolation between users of RS-232C. Three 1x8 amplifier circuits allow the incoming signal to be distributed via 24 outputs. The units receive RS-232C and buffer the signal so that each of the 24 outputs can drive a single user at a distance of up to 50' (per output). All inputs and outputs for the ES-250 are via rear mounted terminal block connectors; the ES-251 inputs and outputs are via rear mounted 9-pin D-sub connectors.
