RS-232C Serial Connector
A serial cable is
provided with each
8TraXX.
This input is a standard DB-9 male RS-232C connector, intended to be connected to
a PC or control system using a straight-through (not null-modem) 9-pin cable. The
pinout appears below. Please refer to the Serial Protocol section for a list of control
commands.

5 GND
MIDI In and Thru
These 5-pin DIN connectors provide the MIDI control interface to the unit. The
8TraXX uses standard control change MIDI command protocol. Please refer to the
Serial Protocol section of the manual for a list of commands.
Configuration DIP Switches
There are two small switches near the power connector.
Ground Lift
In the event of AC hum or noise, this switch may be set to the off position to isolate
the 8TraXX circuit ground from the chassis.
Contacts/Voltage Inputs
Be sure to configure the
8TraXX’s switches
before connecting the
parallel control
interface.
This switch configures the parallel control inputs for either dry contact closure operation or
voltage input operation. For voltage input operation, the input voltage should be at least
12VDC and not more than 24VDC.
Power
The power input is a 2.5x5.5x10mm barrel connector with center pin (+) and the
outer rim (-). The 8TraXX requires a minimum of 9VDC at 1 Amp. It may be
operated from a vehicle battery or other DC source, as long as the input voltage does
not exceed 14VDC. An external 115 or 230 VAC power supply is provided with the
unit.
