The ACT-1B is an economical and easy-to-use digital tachometer that
displays rotaonal speed directly in RPM or RPS on a 5-digit red 0.56"
high LED display using a speed sensor providing a single (or mulple)
pulse(s) per revoluon. The number of pulses per rev is factory set at
me of ordering and can be user programmed from 1 to 999 using the
oponal USB Programming Cable and PM Remote Soware. Power may
be either universal 100 to 240 V ac (50/60Hz), or oponally, 12 V dc or
24 V dc isolated. The ACT-1B accepts input signals from opcal, proximity,
magnec, infrared or laser sensors, or direct TTL or external ac inputs. The
ACT-1B is suitable for panel mounng or benchtop use with convenient
screw terminal connecons on the rear panel of the instrument.
If specied at me of order placement, the ACT-1B may be equipped with
either an oponal 4 to 20 mA current output (IO) or 0 to 5 V dc analog
output (AO) proporonal to speed, and/or a TTL pulse repeater output (PO).

the specicaon indicated on the rear panel. Refer to Figure 2 below.
If the unit is AC powered (100-240 V ac), connect the live (hot) wire

A speed sensor (not included) is connected to the terminals under the
secon labeled INPUT on the rear panel. Refer to Figures 2 and 3.
Connecons and their funcons are as follows:
 Posive +12 V dc to provide power to opcal, laser, infrared or
amplied magnec sensors. Maximum load is 75 mA dc.
Oponally 5 or 24 V dc supply may be ordered.
PX+ Posive +12 V dc supply for use with two-wire proximity sensors.
Maximum load for proper operaon with two-wire sensors is
25 mA.
SIG Posive input signal from the speed sensor. Accepts TTL pulses or
ac signals, unipolar and bipolar, from 1.5 V ac to 50 V ac. (Contact
the factory for increased sensivity.) Connect the signal wire from
three-wire sensors or the posive side of two-wire magnec
sensors to this terminal. Typical input impedance is 10 kilo ohms.
COM Common or Negave connecon for both signal and power from
most sensors.
Refer to Figure 3 (next page) for connecon of Monarch standard sensors.
The connecons are typical for these types of sensors.

Programming the unit requires the oponal USB Programming Cable with
associated PM Remote Soware 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.
Communicaon requires the USB Programming Cable.
@PI Product Informaon, Shows Product name \n Firmware revision \n
@C2 Shows all sengs
@D0 Sends current display value once
@D1 Sends display data connuously (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 the 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 tachometer shows 0.

11
@CH_A/LOEND = 12 (or 1_SEC, HALF) Sets low end me. This allows a
min reading of 5 RPM, 60 RPM, or
120 RPM
@CH_A/GATE Shows Gate Speed (default is 12)
@CH_A/GATE = STD (1/100 Second) or FAST (1/1000 second)
Sets Gate Speed (default is 1/100)
@DECPT Shows the number of decimal places displayed
@DECPT = NONE, 1, 2, or 3 Sets the maximum number of decimal
places
@DAC1/ FSCAL Shows Analog Out Full Scale
@DAC1/FSCAL = xxx.xx Sets the Reading value that the Analog output
will output Full Scale (5 V or 20 mA) depends
on TYPE
@DAC1/0SCAL Shows Analog Out Zero Scale
@DAC1/0SCAL = xxx.xx Sets the Reading value that the Analog output
will output Zero Scale (0 V or 4 mA);
depends on TYPE (default is 0.00)
@OUTPT Shows pulse output polarity
@OUTPT = POS or NEG Sets pulse output polarity
@DISPR Shows Display Update Rate
@DISPR = HALF or 1_SEC or 1.5_S. This sets the maximum display
update rate to one half a second, 1
second or 1 ½ seconds between
updates
@SERNO Shows unit Serial Number
