Controller Address Setting
The rotary switches set the hardware address which the software uses to identify each
particular display. Each controller in a network needs a unique address.
To set the rotary address switches, rotate them until the arrow points to the desired
number. The display’s power must be turned off and then turned back on to activate the
test mode or to change an address.
Note: Setting both rotary switches to address 0 will activate Test Mode. Turn the
display’s power off and back on to activate testing.
After testing, reset the rotary switches to an address other than 0/0 and repower
the controller (the software will not recognize an address of 0).
Power Supply Replacement
VL-35X0 Series displays use 135-watt power supplies. Each module is connected to a wire
harness on the power supply by a Mate-n-Lok
®
cable. Refer to Figure 16 for an example.
Complete the following steps to replace a power supply:
1. Turn off power to the display.
2. Remove the module directly in front of the appropriate power supply.
3. Disconnect the Mate-n-Lok
®
connectors from the power source as well as those
going to the modules. Be sure to label each connector so that it can be properly
reconnected.
4. Loosen the screw holding the power supply bracket to the cabinet upright and lift it
off the hooks.
5. Carefully pull the power supply out of the cabinet.
