The SER-COMi-SI-M is used to convert RS-232 signals to RS-422/485 signals. The converters provide instant connectivity to RS-422/485 communication devices for factory automation equipment, multi-drop data collection devices, barcode readers, time clocks, scales, data entry terminals, PC to PC long distance communications (up to 1.3KM) and serial communication in harsh environments.
The SER-COMi-SI-M provide an industrial solution for applications requiring single node or multi-drop communications over short and long distances. In RS-485 half-duplex mode, SER-COMi-M and SER-COMi-SI-M also provides automatic data transmit/receive control.
The SER-COMi-SI-M converter is optically isolated with 2000 Volt DC optical isolation. The optical isolation protects your PC from spikes and surges on the RS-422/485 network, by converting the electrical pulse into an optical signal and then changing it back into an electrical pulse. Your computer is well protected, since the surges and spikes cannot cross the optical link. The SER-COMi-SI-M is protected by surge protector to withstand electrostatic discharge and power surges up to 25kV ESD. Surge suppression on all signals prevent from damages caused by lightning or high voltage.
