2.8.16 MISCELLANEOUS JUMPERS

The following jumpers are installed in the factory as required. This explanation is provided in case they are accidentally removed and must be replaced.

Security Option Jumpers on J5. Unless a Security Option Interface Cable is plugged into J5 on the Main Board, jumper plugs must be installed at J5 pins 4&5 and pins 7&8.

Option Jumpers on J10. If the Option tray is not installed, a jumper must be placed at pins 13&14 of J10. This jumper allows normal operation of the unit when the Options Tray and the Options Interface Board are not installed.
