The Model 1140F-ST miniature fiber optic modem goes all out to ensure RS-232 communication integrity. Combining the inviolability of fiber with the troubleshooting capabilities of V.52 and V.54 diagnostics, these modems are the best choice for your most critical RS-232 links. Besides communication integrity, this model offers substantial flexibility. Supporting distances to 2 miles (3.2 km) and data rates to 19.2 Kbps over two fibers, it operates Async or Sync, full or half duplex, with the carrier options of "Continuously On" or "Controlled by RTS". This fiber modem draws all necessary operating power from the RS-232 interface requiring no AC power or batteries. While in synchronous mode, the Model 1140F-ST supports three clocking methods: internal, external and receive recover. The modem is housed in a sturdy pop-open/snap-shut ABS plastic case that allows easy access to the configuration switches. Specifications - Transmission Line: Dual multi-mode optical cable
