Section 4.1 discusses terminal port operation, Section 4.2 discusses
composite port operation, Section 4.3 discusses the different
operating modes, Sections 4.4 and 4.5 discusses the LEDs and
SELECT switch functions, and Section 4.6 discusses data flow
control.

The TX102, TX104, and TX108 multiplex two, four, or eight lines of
data respectively. Multiplexed data is sent sequentially over a single
telephone communication line or cable. Data is then automatically
demultiplexed by a remote Telplex with distribution of data to
designated terminal ports. Individual terminal ports may be
programmed to allow the device connected to it access to System
mode for multi-drop units or Local mode for standard units.
NOTE: Standard units will only support a "point-to-point" application
as shown in Figure 1 on Page 2. Port 1 of the local unit will
communicate with Port 1 of the remote unit, Port 2 with Port 2, and so
on. Multi-drop units allow you to program the specific remote port a
local terminal port will communicate with once both units go into MUX
mode.

You may program the baud rate, word size, stop bits, parity,
XON/XOFF handshaking and RTS/DSR pass through for individual
terminal ports. Please see Section 2 for a list of available serial
parameters. The Telplex will translate for devices using different
configurations. The factory default Serial Port Configuration is
9600 baud, 8 bit word size, 1 stop bit, no parity, XON/XOFF
handshaking and RTS/DSR pass through disabled for all ports.
