SERIAL PORT SETUP Display Mode
The SERIAL PORT SETUP display is useful during startup when the FEM-03 serial protocol (OPTOMUX) is
used for communication. Use this display to set the baud rate and unit number while in program mode,
or observe communications in display mode. To aid in startup and troubleshooting, the FEM-03 SERIAL
PORT SETUP screen displays any incoming strings in the RECEIVE line, and the FEM-03 response string in
the SEND line. When initiated, the FEM-03 SEND buffer contains the ASCII string “FEM.” To test
communications, the FEM-03 transmits the string shown in the SEND buffer plus a cr (carriage return)
each time you press the RESET DN key.
PRINTER SCR
The PRINTER SCReen displays the status of printer functions and the elapsed time since power was most
recently applied. The display indicates whether the PRINTER function is active and whether TIME PRINT
is operating. Whenever the display indicates active, the hardware print request input activates in
addition to any other print function. Although the display indicates active, the TIME PRINT function
defaults to a deactivated state whenever power to the FEM-03 is cycled. This prevents unexpected
printing activity. The operator must reactivate The TIME PRINT function after each power cycle. See
PRINT Functions/Operations on page 31 for complete information regarding FEM-03 printer functions.
Programming the FEM-03
Program all FEM-03 parameters from the corresponding display screen. For example, to program the A
Channel Rate scaling factor and engineering units, select RATE A PL or RATE A GT.
Most applications require programming of rate and total parameters, with additional parameters in
order to utilize limit outputs, serial communications, or the analog output (when applicable). In order to
program variables, the appropriate display mode must be active and on screen.
Basic Key Strokes
Using the UP key, first select the display mode for the area which you wish to edit or program. Press and
hold the ENT key. The display first shows a P in the lower left-hand corner and then displays the first
program variable for that mode. All parameters related to that display mode appear in order until you
