1.0 OVERVIEW

7.0 APPENDIX A - Serial programming Commands

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.

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.

Before mounting the unit to a panel all user options should be set. See
Sections 3 and 4.

2.1 Power

Power to the unit is connected to the 4 way terminal block marked DC
INPUT 12 – 24Vdc. Refer to Figure 2.1 above. Note that these inputs

are polarity sensitive. Connect a supply of 12 to 24Vdc (with a 150mA
source capacity) ensuring that the positive wire goes to the + terminal
and the common or negative wire goes to the – terminal.

2.2 Analog Out

The Analog Out terminals are the source for the voltage or current
output as ordered. These terminals are polarity sensitive and are marked
+ and – accordingly.

The F2A1X Frequency to Analog Module may be equipped with either
a Current Output or a Voltage Output depending on how the unit was
ordered. The Analog Out terminals are the source for the voltage or
current output. These terminals are polarity sensitive and are marked +
and – accordingly.

The ANALOG OUT is an OUTPUT. DO NOT CONNECT THE
DC POWER TO THESE TERMINALS.

NOTE: The Full scale output settings must have been specified when

ordered or may be user programmed using the User
Programming Cable.

2.2.1 Current Output Option

The current output is 4 to 20 mA. This output is a current source
and has a 10 Vdc internal compliance voltage. The maximum load
that may be connected is 450 ohms.

Typical connections are as follows: (Shown
right)

Connections for current out are to the terminals
marked ANALOG OUT. Connect the Positive
side of the load to the terminal marked + and the
other side of the load to the terminal marked -.

2.2.2 Voltage Output Option

The voltage output is 0 to 5 Vdc.

Connections for voltage out are to the terminals
marked ANALOG OUT. Connect the Positive
side of the load to the terminal marked + and the
negative or common side of the load to the terminal marked -.

2.3 Sensor Input

The SENSOR INPUT is the input terminal used to connect an external
sensor or trigger source. There is a voltage output that may be used to
power an external sensor (5 or 12 Vdc – user selectable at 75mA max).
The system supports two wire inputs (Signal and Common) or three
wire sensors (Supply, Signal and Common). Three wire sensors can be
open collector types – NPN or PNP, TTL output or –ve output types.

4.0 USER PROGRAMMABLE SOFTWARE

SETTINGS

All the operational settings of the F2A1X
Frequency to Analog Module can be set remotely
using the PM Remote PC Software and the
optional User Programming Cable (UPC). This
cable plugs into the unit via the phone jack socket
below the SENSOR INPUT terminal block as
shown here and into a USB port on the PC.

Settings that can be programmed include input scaling, analog output full
scale and offset, input pulse polarity and update rate. In addition you can
view real time data on the PC – refer to the PM Remote manual and help
screen.

Connections and their functions are as follows:

+Vout Positive +5 or +10 Vdc (User selectable) to provide power to

optical, laser, infrared or amplified magnetic sensors. Maximum
load is 75 mA dc.

SIG IN Input signal from signal sources or speed sensor. Accepts

TTL pulses or ac signals, unipolar and bipolar, from +3 to
+12 Volts. Connect the signal wire from three wire sensors or
the positive side of two wire sources to this terminal. Typical
input impedance is 10 Kohms.

COM Common or Negative connection for both signal and power

from most sensors/sources.

Refer to the User Settings section for input option settings. Typical
connection for Monarch standard sensors is shown below:

3.0 USER PROGRAMMABLE HARDWARE

SETTINGS

There are several settings relating to the sensor input that can be set by the
user.

The settings are done by moving jumpers on the circuit board inside the
housing. To access these jumpers REMOVE ALL WIRING FROM THE
UNIT. Then remove the two screws on the bottom of the unit and remove the
base exposing the circuit board as shown below.

There are three jumpers as shown in Figure 4. These are:

3.1 Sensor Power Voltage

This jumper adjusts the supply voltage to the external sensor. Can be
set as +5Vdc or +10Vdc depending on the sensor used. Factory Default
is +5V.

3.2 Sensor Termination

This jumper sets the input termination. Can be set HI for 10k pull up
resistor (to sensor supply voltage) for NPN type open collector sensors
(factory default) or LO for 10k pull down resistor (to Common) for
PNP type open collector sensors or none (remove jumper altogether)
high impedance input for external termination.

3.3 Input Coupling

This jumper sets the input coupling for the external signal. Can be set to
DC (default) for most digital input sources or AC for sine wave and
bidirectional sources or sensors that provide negative going pulses.

Once the jumpers have been set, replace the base and the two screws.
