The Model 1003 Async., 2-Wire, Carrier Sense Short Range Modem combines the 2-wire capabilities of the Model 1002 with the carrier sense capabilities of the Model 1005. The result is a versatile short haul that allows RS-232 UNIX systems (and similar systems that require carrier sense handshaking) to communicate over coax or a single twisted pair.
The Model 1003 is particularly applicable to environments where coax cable is already installed, or where there is a desire to double the carrying capacity of existing twisted pair lines. Besides its usefulness in UNIX environments (where the host must see carrier to send a logon screen to a terminal), the Model 1003 is also tailored for troubleshooting in systems where the presence or absence of carrier indicates positive or negative line integrity.
The Model 1003S incorporates 600 Watts per wire of Silicon Avalanche Diode surge protection on the line side.
