4 SERIAL PORT to E1 Converter

4 Serial port to E1 converter takes data from four different serial ports and converts into single E1 line and vice verse. Equipments like Data logger, RTU’s, PC. etc., can be connected to single E1 network. No. of E1 networks used will be decreased by using this device because at a time data coming from 4 equipments can be routed to single E1 line. Supports up to 30dB attenuation and distance up to 1.5km.

User selectable test modes are used for both line and converter checking. BERT switch activates Pseudo random pattern for complete end to end testing and ERR LED indicates for certain count of errors.
