TX – 30 PROTOCOL TRANSLATOR
Revision 0.2 OWNERS MANUAL 03/02/2005
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.
DMX IN
OPERATION
The TX-30 translates and sends LMX-128 automatically when power is appli ed 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 th e
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.

TX192 OPTION
The TX-30 may be optionally supplied to transmit the AMX-192 protocol. This model transmits both LMX and
AMX simultaneously. An external power supply is included and is needed with this option. The AMX-192 output
signal is transmitted from a 4 pin, male, XLR connector located at the rear of the unit.
CAUTION: Some AMX dimmer equipment uses a 4 pin MINI-DIN connector for the control signal. That
connector is NOT wired the same as the 4 pin XLR connector. The following table provides the information
needed to make an adapter cable.

EXTERNAL POWER SUPPLY INFORMATION
Input Voltage: 120VAC
Output Voltage: 13.5 VAC
Output Current: 800 Milliamps
Connector: 2.1mm female connector
The TX-30 will operate using an alternative external power supply which can provide anywhere from 13 to 24
Volts AC or DC. The supply must be rated at 600 ma. If a DC supply is used, the center pin of the connector
MUST BE THE NEGATIVE output terminal of the supply.
MAINTENANCE AND REPAIR
TROUBLESHOOTING
Verify the cables (a very common source of problems!).
Ensure that a ll system units are powered - particularly the dimmer to which the translator is connected.
Check address settings at dimmers, console, and translator. Check console patch configuration.
REPAIR
There are no user servicable parts in the unit. Internal service by other than Lightronics authorized agents wi ll
void the warranty. If service is required, contact the dealer from whom you purchased the unit or contact the
Lightronics Service Dept..

ADDRESS SETTINGS TABLE
The DIP Switch Setting column shows the positions of the DIP switches on the TX-30. The Start Channel column
shows the resulting DMX channel assignment for the first TX-30 LMX output channel (channel 1). The left end
two DIP switches are not included in the table since they do not affect the address settings.
NOTE: Some control consoles and dimmers can be programmed or "patched" to alter their channel order. You
may get unexpected results if you are not aware of the patch condition when you set the TX-30 address switch es.
EXAMPLE: If the dimmer's DIP switches are set to ШШГШГШГГ : the first channel of the dimmer will respond
to console channel 87. The remaining dimmer channels will respond to console channels 88, 89, 90, …etc.
