Connecting The Power & Signal Connections For End Mounted Signs
It is recommended that the LD-IT SignalLED end mount sign installation tool is used to assist
the termination of the power and signal connections. The tool is designed to hold the sign
on the pre-tted wall mount plate leaving both hands free to make the connections, as
shown in Fig. 2-7.

To get access to the cable connection block and the mode switches, which are on the PCB
inside the sign, the door on the underside of the end plastic moulding must be opened.
To open the door push the clip towards the sign and pull
down on the small lip. See Fig 2-8. Do not attempt to
remove the door from the end moulding. Access to the
connection block and the mode switches is possible with
the door fully open.

Power Supply
The sign can be connected and powered either with the supplied DC power supply, or with
a regulated DC supply rated 5V to 7V DC, 0.5A minimum. Please note that the current that
a power supply can supply, will be aected by the type of wiring used and its length, i.e. it’s
total impedance. See website FAQs for more details. On the supplied DC power supply, the
+6V is indicated with a dashed white line on one of the cables.
Pin 1 (Signalling Input 1)
Pin 2 (+6V) @ 500mA
Pin 3 (0V)
Pin 4 (Signalling Input 2)
Please note it is essential that the ground pin (pin 3) is connected properly before powering
up the sign, or rmware corruption may occur. The signalling inputs are used to control the
