There are three display variants available for an AK-CC55 controller:
AK-UI55 Set (keyboard version)
AK-UI55 Info (display only)
AK-UI55 Bluetooth (Bluetooth version)
Up to two displays can be connected to an AK-CC55 case controller via RJ12 connectors.
If only one display is connected to the controller, the maximum cable length is up to 100 meters.
If two displays are connected, their combined cable length can be up to maximum 100 meters from the controller.
Example with two displays:
If e.g. one display has a cable length of 20 meters and the second display has a cable length of 80 meters, the combined length is 20 + 80 = 100 meters, which is acceptable.
