5494 Operator Panel Components
   The operator panel is located on the right-hand front side of the 5494 and consists of a keypad, an LCD, and four LEDs (Ready, Call 5494 Service, See PD Guide, and Test Mode) that indicate operating status.  An 8051 microprocessor controls the LCD, LEDs, and the keypad.  Communications between the planar and the operator panel are through a serial port. 

The LCD has 16 character positions. It is blank and displays a cursor in 
| the rightmost position when not in use. When the 5494 operator panel is in use, there will always be a message code (002-01 in the above example) displayed on the left-hand side of the LCD. The message codes are described in "Message Codes" in topic 3.1. When the 5494 is in use, the LCD can also contain, in the data field on the right-hand side of the LCD, a system reference code (SRC) or information as defined by the message code. In the example, the data field contains an SRC. 

If an error occurs before or during normal operation, both a message code and an SRC will be displayed on the LCD and an LED will be lit. If more than one error occurs during normal operation, the message codes and SRCs will cycle at 3-second intervals. If the error clears (a link is established after a failure, for example), the message code and SRC will be removed from the LCD by the 5494.
