The BayTech Model 24H is a user-programmable, multifunction device
that allows serial port expansion/sharing, time division multiplexing, and
message multiplexing. This solution is ideal for adapting small
computers like the IBM PC to industrial process control and data
gathering applications. Up to twenty-three peripheral devices may be
multiplexed to a single host computer or terminal.

You may select from six modes of operation. Other programmable
features include the serial port configuration for each individual port,
the data block length, the message terminating character, and the port
select code. These features are programmed by accessing the menu-
driven configuration mode.

The Model 24H will translate for devices using different serial
configurations. You may set the baud rate, word size, stop bits, parity
and XON/XOFF handshaking for each individual port.
Factory default configuration on serial ports is 9600 baud rate, 8
bit word size, 1 stop bit, no parity and XON/XOFF disabled.

You may configure parallel ports on the Model 24H to be either input or
output. For parallel ports defined as input, data will flow from the
peripheral device to the host device only. For parallel ports defined as
output, data will from the host device to the parallel peripheral device
only when the host device selects the parallel peripheral port.
Factory default parallel port destination is input for all parallel
ports.
