The Patton Model 1140A 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, the Model 1140A is the best choice for your most critical RS-232 links. With respect to communication integrity, optical fiber has some important advantages over twisted-pair copper. Copper wire requires shielding against RFI/EMI noise in many environments, whereas fiber is immune to RFI/EMI. In building-to-building applications, copper wire requires DC isolation to avoid ground looping. Fiber, on the other hand, does not have DC continuity, so it is not subject to ground looping. If a copper link passes through a field of energy created by a lightning strike, the transient energy will be conducted to the hardware at either end. But a fiber link will not pick up this harmful radiated energy-It is immune to transients. The Model 1140A brings all the advantages of fiber to your network, plus 100% compliant V.52 and V.54 diagnostics. Besides communication integrity, the Model 1140A offers substantial flexibility: Supporting distances to 5 miles (8 km) and data rates to 38.4 Kbps over two fibers, the Model 1140A operates Async or Sync-full or half duplex-with the carrier options of Continuously On or Controlled by RTS. The Model 1140A fiber modem draws all necessary operating power from the RS-232 interface and requires no AC power or batteries. While in synchronous mode, the Model 1140A supports three clocking methods: internal, external and receive recover. The 1140A is housed in a sturdy pop-open/snap-shut ABS plastic case that allows easy access to the configuration switches, and ridges for sure grip.
