UTILITY

RS485 CTRL.

Remote control of Preset change, Delay time and Bypass is implemented in the D22 by using a RS485 controller.

All remote control capabilities are enabled/disabled by the REMOTE key. All displays and key states are updated according to incoming remote control info, i.e. the Delay time on the Recall page is always indicating the actual Delay.

The command structure for a Program change is: #AA,<PRE>,<NUM><CR>

The command structure for changing Delay time is: #AA,<DEL>,<delay in current mode><CR>

The command structure for changing Bypass mode is: #AA,<BYP>,<0/1><CR>

CR=ASCII 13
