The CVT-485_422-4 is a high-speed (300 to 115,200bps), optically-isolated, externally-powered RS232 to RS485 converter / RS232 to RS422 converter, which can be used to convert any standard RS232C port into a two-wire half-duplex RS485 port or a four-wire full-duplex RS485 / RS422 port and vice versa. This industrial externally-powered opto-isolated RS232 to RS485 / RS422 converter supports multi-drop RS485 / RS422 networks and can be used to communicate with one loop of up to 128 units of RS485 / RS422 devices. It operates within a temperature range of -40ºF to 185ºF (-40ºC to 85ºC), features 600W surge protection, 15kV ESD static protection and 2500V opto-isolation circuitry, which effectively protect your RS232 devices from ground loops, noise problems, transient surges, remote lightning and spikes. The unit is powered from an external 9 to 30VDC power supply, so you do not have to worry about the power ability of your RS232 device; it also supports data direction auto-turnaround, which automatically enables the RS485 transceiver when data is present on the RS232 side. Therefore, it requires no port power, software drivers, or DIP switch settings. The built-in 120-Ohm terminator can be turned ON or OFF through a simple jumper wire, thus making the unit an ideal solution for all types of installations. A separate external power supply is included in the package, and, thanks to the professional and unique casing design, the product can be mounted directly on a wall, panel or DIN Rail, without a need of using any unsecured DIN-Rail or wall-mount brackets.
