描述： Send RS-232 data four miles at 19.2 kbps or up to 15 miles over 24 AWG wire at 1200 bps! 规格：
Plug-and-play. Put one unit on each side of the dry copper pair, connect your T1 devices, and go. Use only two polarity-insensitive pins so you can connect either wire to either pin. Operate in Clear Channel mode to easily transport voice and data circuits (F-bit included.) Check status via the front-panel LEDs. Rackmount panels are also available.
Requiring zero configuration, this plug-and-play T1 extender communicates over voice-grade twisted-pair cabling, enabling you to get more distance with fewer copper pairs.
