"500H" Series and the Model 24SII DAC Data Acquisition and
Control units connect between one host computer and multiple
peripheral devices. These models are often used in industrial
process-control environments (e.g., for allowing control of multiple
numerical or assembly-line machines), in exchanging data between
point-of-sale devices, or for operating a number of laboratory
instruments or business machines from a central computer. They are
especially effective in adapting small low-cost personal computers to
these applications. Each unit features six modes of operation which
may be easily configured to your application. The 500H series
models are available with either 5 or 9 ports. The Model 24SII DAC
unit is expandable from 4 to 24 ports in 4-port modular increments.
Telplex Models TX104 and TX108 are asynchronous statistical
multiplexers which multiplex and demultiplex four or eight
communications channels over a single channel. This single channel
is typically a telephone line or cable. The TX24 will multiplex and
demultiplex up to twenty channels. Programmable features include
serial port parameters (baud rate, word size, etc.), data flow control,
user-programmable strings to be sent to an external modem, and
remote diagnostics/configuration capability. These units must be
purchased in pairs.
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.
