Slim Industrial RS232 to RS485 Adapter

Model: CVT-485A-1

The CVT-485A-1 is a slim, rugged, industrial-grade, port-powered RS232 RS485 converter, which can be used to convert any standard RS232C port into a two-wire half-duplex RS485 port and vice versa. This industrial RS232 to RS485 converter supports multi-drop RS485 networks and can be used to communicate with one loop of up to 128 units of RS485 devices. The device is efficiently powered from the RS232 data line (less than 8mA of power consumption), and it supports data direction auto-turnaround, which automatically enables the RS485 transceiver when data is present on the RS232 side. Therefore, it requires no external power, software drivers or flow control.

This slim RS232 to RS485 converter comes with a 5-way terminal block which can be attached to the converter securely without using screws and nuts, and the innovative 120-Ohm end-of-line terminator design makes the termination easier than ever before, thus making the unit an ideal solution for quick installation and space-restricted applications.
