2.2DESCRIPTION

The Model 1070 Series synchronous short range modem is equipped with a virtual wish list of “bells and whistles”: Point-to-point or multipoint applications are supported. Two separate control signals may be passed (one each way): RTS and DCD. Data lines are protected from ground loops and electrically volatile environments by optical isolation and Silicon Avalanche Diodes. System integrity can be evaluated using two test modes: local analog loopback and remote analog loopback. Tri-state LEDs monitor transmit data, receive data and control signals. Finally, 4-wire connections may be made using either an RJ-11 jack or terminal blocks—both are included.

In addition, the Model 1070 is perfect for low power RS-232 applications. The new Model 1070 is AC powered and recommended for low power RS-232 environments. The Model 1070 supports switch selectable data rates to 19.2 Kbps, and extends RS-232 transmission distances up to 10 miles over two twisted pair.

The Model 1070 is housed in a sturdy metal case, and comes with either 115 or 220V external transformers. This is the top-of-the-line in synchronous short range modems.

3.0 CONFIGURATION

The Model 1070 uses a set of eight external DIP switches that allow configuration to a wide range of synchronous applications. Because all eight switches are in one externally accessible DIP package, there is no need to open the Model 1070's case for configuration. The switches allow you to control line contention, clocking methods, RTS/CTS delay and data rates. Figures 1 and 2 (below) and Table 1 (opposite page) summarize the switch locations, positions and functions.
