Optical Isolated Input, 16 Channel Switched Input, EIA-232/422 4
serial I/O ports, or EIA 485/422 4 serial I/O ports. System
configuration and comprehensive data collection functions are
provided through module configuration menus.
Telplex Models TX102, TX104 and TX108 are asynchronous
statistical multiplexers which multiplex and demultiplex two, four, or
eight communications channels over a single channel. This single
channel is typically a telephone line or cable. The Telplex TX24,
TX28 and TX60 will multiplex and demultiplex up to 20, 28, and 60
ports respectively. The TX28 and TX60 support ethernet, taken ring,
EIA-232, EIA-422, V.35, and DDS communications. A Telplex pair
may be connected using high speed asynchronous or synchronous
modems or via cable up to 4000 feet. Telplex allows local and remote
configuration and diagnostics. A terminal connected to a local Telplex
may configure or perform diagnostics on the local unit. This same
terminal may also configure or perform diagnostics on a remote
Telplex if there is a communication link with the remote site. You may
use Telplex in point-to-point, multiple location, daisy chained, or star
configuration applications. The TX28 and TX60 allow for multiple
composite modules which offer simultaneous communications with
multiple remote locations.
Telplex Model TX104M is an asynchronous statistical multiplexer with
built-in modem. Four individual communications channels are
multiplexed into a single dial-up or leased telephone line, cutting
phone line costs to a minimum. The TX104M features a V.22 bis
internal modem which provides reliable communication at speeds up
to 4800 bps. With V.42 bis protocol, the TX104M provides error
correction and Classes 2-4 data compression. Compatible with most
computers, printers, or peripherals, the TX104M ensures rapid
throughput, and offers a variety of user-programmable features in
order to meet your specific application requirements.
The BX2448 is a V.22 bis external modem which uses deal-up or
leased telephone lines and comes equipped with many advantageous
features, such as MNP Class 5 data compression, which enables data
transmission at speeds to 4800 bps and, MNP Classes 2 - 4 error
correction. A wide selection of user-programmable features allows
you to customize the modem to your own individual application.
