RS-232 to RS-422/RS-485 Converter with Surge Protection, Port Powered or Optional Power Adapter

Antaira Technologies STS-1915S is an RS-232 to RS-422/485 serial converter. Designed to work as either a client or server, the STS-1915S is able to provide RS-422/485 serial communication through the standard RS-232 port. The STS-1915S is equipped with a standard DB-9 female connector and serial terminal block for flexible wiring. The serial converter can be either powered by the RS-232 line voltage or a USB to barrel 5VDC input jack.

The STS-1915S can convert between unbalanced RS-232 full-duplex signals to balanced RS-422/485 full or half-duplex signals. The RS-485 serial is able to be configured in either a two or four-wire configuration. The serial converter is compatible with both new and legacy RS-422 and RS-485 devices. The STS-1915S is easy to install and does not require the user to power cycle the computer, preventing downtime.
