OPERATION
Diagrams showing signal and power connections for
both the portable and wall mount units appear below
and on the following page.
Operation is automatic when the power supply and a
DMX input signal are connected. The front panel
contains a power indicator LED which is lighted when
power is applied. A "DMX VALID" LED indicator is
lighted when a DMX input signal is present.
POWER SUPPLY
The DI-104 will operate using any external power
supply which can provide 13 - 24 Volts AC or DC at
600 ma. The power supply provided with unit is
13VAC, 800 ma. The size of the power input
connector on the unit is 2.1mm. If an external DC
power supply is used, the center pin of the connector
MUST be the NEGATIVE side of the supply.
MAINTENANCE
There are no user servicable parts in the unit. The 1/8
Amp fuses are axial lead fuses soldered directly to the
internal circuit card. These fuses could be replaced by
a qualified technician but the warranty could be voided
if the circuit board is damaged during a repair by other
than a Lightronics authorized agent.
Dealer and Lightronics Factory personnel can help you
with operation or maintenance problems. Please read
the applicable parts of this manual before calling for
assistance.
If service is required - contact the dealer from whom
you purchased the unit or contact Lightronics, Service
