The Anti-Streaming RS-232/422 Multimode Line Terminating Transceiver from ComNet can be used as a terminator at the receiving end. It is designed for implementing full-duplex RS232 drop-and-repeat poll-and-respond traffic signalization/communications data networks utilizing two optical fibers. This environmentally-hardened unit is suitable for use in unconditioned out-of-plant or roadside installations. The master-configured transceiver unit may be located anywhere within the network. This makes it suitable for applications involving on-street master controllers with upstream and downstream communication requirements.
The Anti-Streaming RS-232/422 Drop-and-Repeat Data transceiver is compatible with the FDX50, FDX51 and FDX52 Series of optical modems (not included). Manually re-settable anti-streaming is included for unparalleled network protection. Plug-and-play design ensures ease of installation as no electrical or optical adjustments are required.
