Why does the LCD remain blank on the KBD300A In Matrix Mode, ASCii Mode, or Direct Mode.
- Matrix Switcher
- Installation and Service.
- Connecting the KBD300A to a matrix and is expecting the number on the KBD300A to display the camera number.
- The LCD doesn't default to 01 in direct mode.
The KBD300A or KBD200A will not display the camera number when connected to a matrix system when configured to Matrix Mode or ASCii Mode.
If the KBD300A is configured to Direct Mode then there is a short on one of the transmission leads. Check continuity accross PINs 1 and 2 on the KBDKIT be sure it is open or does not tone out.
