1. Press and hold the ENT key to access the parameters for the serial port. A “P” appears in the
lower left hand corner and SELECT SPEED appears in the second line of the display.
2. Use the SEL key to select from the four available choices:
9600 (default) 19200 38400 57600
3. When the desired baud is displayed, press ENT to store. UNIT NUMBER appears next in the
second line with the blinking cursor highlighting the left-most digit. The initial value is 001.
4. Select the digit to edit using the SEL key. Use UP or DN to increase or decrease the value.
5. When the desired value displays, press ENT to store and exit the SERIAL PORT SETUP program
mode.
The FEM can have a unit number from 1 to 200 although only one unit can be addressed at a time on the
serial line with RS232 communication. If RS422 or RS485 communications are accomplished using
converters, up to 200 units can be addressed and accessed individually using the OPTO22 Company
OPTOMUX serial protocol.
FEM-03 Printer Functions/Operation
The FEM-03 supports some basic print functions when connected to a standard parallel printer using a
serial-to-parallel converter. The FEM-03 generates a printout of the current elapsed time since power-
on, a sequential printout number, Rate A
PL , Rate B PL , Job TOTAL A, and Job TOTAL B. You can initiate
these on a timed basis or single printouts via the touch-keys or a hardware input. In addition, the FEM-
03 can generate a printout of all the programmed values.
The PRINTER SCReen displays the status of the FEM-03 printer functions (see PRINTER SCReen on page
21) and is used to activate and deactivate printer functions. Once you activate any PRINTER function, the
hardware print request input also activates and remains active (even when power is reapplied to the
FEM-03) until the PRINTER is deactivated through the programming screen. The display indicates
PRINTER ACTIVE after a power cycle to show that the hardware print request input is still active.
However, TIME PRINT operation halts whenever power to the FEM is removed; and it must be
reactivated after each power cycle.
While any PRINTER Function is activated, the OPTO-22 protocol for the serial port is disabled.
Printer Modes
There are four PRINTER operating modes:
