DESCRIPTION
The TX-30 is a very compact in-line translator which receives USITT DMX-512 signals and transmits the
Lightronics (LMX-128) multiplex protocol. This is the industry standard multiplex protocol. The unit is powered by
the dimmer chain to which it is connected or may optionally be powered by an external plug-in power supply.
CONNECTIONS
DMX input is received via a 5 pin male XLR connector. LMX output is via a 3 pin female XLR connector. A 5 pin
female XLR is also provided for the DMX signal “pass thru”. LED indicators display power and input signal status.

OPERATION
The TX-30 translates and sends LMX-128 automatically when power is applied and a DMX signal is present.
LED indicators show the power and DMX incoming signal status.
CHANNEL ASSIGNMENT
The TX-30 translates 192 channels at a time. Eight of the DIP switches on the front of the unit are used to select
the starting channel of the 192 channel block. When all switches are down, channels 1 - 192 are selected.
Channel selection is incremented two channels at a time. A table of address switch settings is included at the
back of this manual.
HOLD FUNCTION
DIP switch number 2 activates a "hold" function. If this switch is in the up position, channel outputs will remain at
their current levels indefinitely upon loss of DMX signal.
DMX TERMINATOR
DIP switch number 1 will terminate the DMX input bus when it is in the DOWN position.
