RS232 to RS422/RS485 Serial Converter-CQR1218

RS232 to RS422/RS485 Serial Converter

Description

RS232 to RS485/RS42 convertor is specifically designed for extending the distance of RS232 and RS485/RS422 bus transmission. It owns a number of independent innovation technology, which including built in data anti-collision; charger and LED indicator light; TVS momentary voltage suppression. To adapt the numerical bus of RS485/RS422, there are many terminal, DB9, RJ45 interface which can satisfied the various wiring modal. The multidirectional bus can contact well and use expediently. The sand blasted aluminum shell can shield of foreign interference effectively and has great heat dissipation.

Lightning protection and against surge, RS232 to RS485/RS422 bidirectional converter. Built-in data collision protection control DCPC function.
Supports transparent transmission and two-way conversion of data.
Super shield, anti-interference, aluminum material, excellent heat dissipation.

CQR-1218 is a universal RS232 to RS485/RS422 bidirectional converter, designed to extend the RS232 transmission distance and the interface converter designed for the RS485/RS422 bus, which consists of a number of CQRobot independent innovation technology. It Includes built-in data collision protection control, the power supply and signal lights and inhibition of TVS transient voltages protection. In order to adapt to RS422 / RS485 with much bus wiring, it provides a terminal at port, DB9 and RJ45 physical interface, that effectively adapt to a variety of connection mode, making the bus from multiple directions to be better contacted and more convenient to be implemented. The equipment adopts the aluminum shell of sandblasting and anti-oxidation, which can effectively shield the external interference and have good heat dissipation.

To prevent the reflection and interference of the signal, a matching resistor is needed at the terminal of the line (the parameter is 120 ohm 1/4w) when the converter is used as full duplex or half duplex wiring.
