Overview
DPS's 8 Port Serial Switch allows you to connect up to eight
data sources to one port on a collection device , such as the Net
Dog 82IP. Commands from an interrogating ASCII terminal
control the switch to route data to the appropriate port. Each
channel has a 16K buffer that allows data to be moved between
ports at different data rates.
Variable Data Rates
In addition to switching between multiple ports, the 8 Port
Serial Switch will select a preset data rate for each port. Avail-
able data rates are 300, 1200, 2400 and 9600 Baud.
T/MUX Software
The MUX is programmed for various parameters with
T/ASCMUX software, running under T/Config software on a
personal computer. The craft port on the front panel is easily
accessed any time the configuration needs changing.
Downloadable Firmware
Future product upgrades will be easy to install with the
downloadable firmware. Simply connect a P.C to the craft port
and load the new firmware from a diskette.

Operation Guide
The 8 Port Serial Switch is available with wire-wrap pins for
external connection or with DB9 connectors.
The Switch consists of nine interface ports interconnected
and controlled by a processor. Associated with each port is a
"docking module" socket that allows the physical interface to
the outside world to be configured to match the associated com-
munications channel or device. This model of the 8 Port Serial
Switch is equipped with RS 232 interfaces on each port.
The 8 Port Serial Switch is housed on a plug-in board that fits
in a 1-3/4" rack-mount housing. The back of the housing pro-
vides DB9 connectors for connecting the associated devices.
The P.C. board can be changed rapidly without removing any
of the connections.
The front panel of the 8 Port Serial Switch provides LEDs for
monitoring unit activity and a craft port for configuration.
There is a fuse alarm indicator on the front panel and a fuse
alarm output relay that activates when the fuse blows.
The 8 Port Serial Switch operates on either -24 or -48 Volts
DC, depending on the option. (Options are described in the Op-
tions and Model Numbers section on page 8.)
