LCD

   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.

The keys on the keypad allow commands to be entered and sent to the 5494, and include: 

REQ Initiates a request function 
PF1 Used for special requests 
PF2 Used for special requests 
Esc Used to cancel a request 
Alt Enables the alternate hexadecimal values of keys 4 through 9, to be used with keys PF1, PF2, and Esc for additional special functions. (Ed. Might be the SHFT key)
Enter Signals to the 5494 the end of an input string 
Clear  Clears a value being entered and allows you to begin again 
0 to 9 Numerics 0 to 9 
Alt+4 Hexadecimal A 
Alt+5 Hexadecimal B 
Alt+6 Hexadecimal C 
Alt+7 Hexadecimal D 
Alt+8 Hexadecimal E 
Alt+9 Hexadecimal F 
Up arrow Scroll up through several choices or panels of data 
Down arrow Scroll down through several choices or panels of data 
Left arrow Move the cursor left or scroll to additional fields of data 
Right arrow Move the cursor right or scroll to additional fields of data. 

   If you hose the refstamp, the 5494 will not boot up and the error code '003-04   1' is displayed on the Op Panel.
