2.2 DESCRIPTION
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.
