APPENDIX C.0 REMOTE KEYPAD

C.1 REMOTE KEYPAD

Support for a remote keypad, that has the same functions as the 10 push buttons on the front dis-
play panel, is activated when datapoint

L72 (Remote Keypad Enable [RMTK]) is set to a 1. Key-

pad entries can be made by either the front display panel push buttons or remotely via 10 normally
open push buttons mounted on a board that is wired to the 6DI/4DO ITB. Figure C-1
illustrates the remote keypad wiring to the 6DI/4DO board. The 6DI/4DO signal cable (p/n

) is still connected from the ITB J5 to the controller J5. If a front display panel push

button and a remote keypad push button are both activated simultaneously, the front panel push
button will have precedence.
