7.3 Communication

When communication of either text or commands is interrupted, try the steps below.

• First, check the communication cable for continuity. If you don't have an ohm meter, try using a

different communication cable. If you are using a PC try using a different Com Port.

• Next, please ensure that the display module is set to communicate on the protocol that you are

using, by checking the Protocol Select Jumpers.

• In serial protocol, ensure that the host system and display module are both communicating on

the same baud rate. The display will communicate at either 9600bps or 19200bps only.

• Match Rx from the MOS-AL162F to the transmitting pin from your host and the Tx pin to the

receiving pin.

• Unlock the display. See the Set and Save Data Lock command for more info.
