Monarch Instrument F2A1X - Manual (Page 4)

1.0 OVERVIEW
The F2A1X Frequency to Analog Module converts frequency input into an
analog voltage (0 to 5Vdc) or current (4 to 20mAdc) output. The output is
electrically isolated from the rest of the unit. The input signal may be from an
external sensor (measuring RPM for example) or any source of digital signal
not exceeding 12 volts.
The F2A1X may be factory preprogrammed or user programmed using an
optional USB programming cable (see Options and Accessories section) for
any full scale output and input scale factor to provide an output of mV or mA
out for a given input signal.
The device is powered from 12 to 24Vdc and consumes less than 100mA and
can be ooperated free standing or can be mounted to a panel using the fixing
wings on either end of the device. The F2A1X accepts input signals from
optical, infrared, laser or 3-wire proximity sensors, or direct TTL or external
ac inputs. User settings include sensor supply voltage, AC/DC coupling and
input termination.
When ordering the user needs to specify either a 4 to 20 mA current output
or 0 to 5 Vdc voltage output and whether isolated outputs are required.
2.0 INSTALLATION
The F2A1X Frequency to Analog Module is housed in a mountable ABS
enclosure 80 x 40 x 28 mm (3.2 x 1.6 x 1.2 inches) excluding the mounting
wings. There are screw terminal connections on both ends of the unit.

7.0 APPENDIX A - Serial programming Commands
Programming the unit requires the optional USB Programming Cable with
associated PM Remote software and a PC running Windows XP or later with
an available USB port.
All serial commands are @ then two or more characters or words separated
by a delimiter “/”. One or two numbers follow some commands. All valid
commands respond immediately with an “OK” or data, or “ERR” if incorrect.
Default Baud rate is 9600. Communication requires the User Programming
Cable.
@PI Product Information, Shows Product name \n Firmware revision \n
@C1 Shows all settings
@C2 Shows all settings with CR after each parameter
@D0 Sends current display value once
@D1 Sends display data continuously (at up to display update rate)
@D2 Stops sending data
@MX Sends Max reading
@MN Sends Min reading
@RE 32 Resets Max
@RE 64 Resets Min
@RE 96 Resets Max and Min
@CH_A/TYPE Shows current type
@CH_A/TYPE = RPM Sets scale to 60 so displays in RPM
@CH_A/TYPE = FREQ Sets scale to 1 so displays in hertz
@CH_A/TYPE = SCALE Scale mode. Enter Scale factor.
@CH_A/TYPE/SCALE = 30.00 This will set the SCALE factor to 30.00
@CH_A/INPUT Shows Sense of trigger input
@CH_A/INPUT = POS (or NEG) Sets the sense of the input trigger
@CH_A/LOEND
Sets how long (in secs) with no pulses
before the unit outputs 0
