Antaira STS-1920SI RS-232 to RS-232 Repeater with Surge and Isolation Protection

Voltage spikes and current overload are not uncommon in electrically noisy environments found on the factory floor and heavy industrial areas. To protect your equipment, you need electrical isolation and surge attenuation. Many legacy machines and computers use serial communication to transmit information. The STS-1920SI from Antaira Technologies was designed to safely protect the RS-232 serial ports used by such devices.

The STS-1920SI is an RS-232 to RS-232 adapter offering electrical surge protection and isolation. It operates with PCs, workstations, thin clients, servers and machines that have standard a RS-232 connection. It is equipped with a DB-9 female connector configured as a DCE port. Pins for 3 RS-232 signals - TXD, RXD, GND - are isolated coupled to the male DB-9 connector which is configured as a DTE port. The repeater is powered directly from the RS-232 signals.
