Establishing Communication with a DX Controller
To establish communication with a DX controller:
1. Connect the serial cable between the display and the controller.
See the Installing the DX LCD Display chapter for details.
2. Connect the cord of the power supply adapter to the display and
plug the adapter into an AC wall socket. See the Installing the DX
LCD Display chapter for details.
Note: There is no power switch on the DX LCD Display. When
you supply power to it, it turns on and begins power on
diagnostic tests.
When the DX LCD Display unit is directly connected to a DX
controller, the diagnostic results shown in Figure 4-7 display.

Note: During initialization, the display attempts to match the DX
controller’s configuration code with one of the eight display
configuration codes stored in the display unit. If it finds a
match, the display uses the corresponding display
configuration. If it does not find a match, it uses the default
configuration if one has been defined. If the default
configuration feature is disabled, the display shows a
Configuration not found message.
