7.2. Diag Mode

The H212 Handheld can be used as a wireless data terminal to read useful
information from the C220 Controller. To enter Diag Mode, proceed as follows:
1. If the H212 Handheld has not been matched with the C220 Controller, match
it as described in the Quick Start Guide.
Interpretation
1. The controller is unable to communicate with its base
(ELR) board; or
2. The controller has detected an error with the PWM
driver chips.
This condition may occur while updating the firmware
of the base (ELR) board using the USB programming
cable, in which case there is no reason for concern. This
condition will clear by itself once the communications
and/or PWM driver has returned to normal.
1. The controller's radio module is not programmed; or
2. The controller's radio module has failed.
Programming or replacing the radio module is required
for the controller to operate.
1. The controller has not been assigned a radio key; or
2. The controller has been programmed with an
incorrect firmware image.
Configuration or reprogramming is required for the
controller to operate.
The controller has detected a hardware failure with its
base (ELR) board. Replace the controller.
1. The controller is not being fed power and ground
properly. The power and/or ground wire(s) is loose
or disconnected, or the 30-way connector is not
completely mated--check the 1/4" hexagonal-head
securing screw; or
2. The base ELR board's processor is not programmed.
The wiring or programming problem must be remedied
in order for the controller to operate.
