How to use this manual
We encourage you to first skim through this guide so that you can familiarize yourself
with the content. Then, carefully read through the sections that are specific to your
requirements.
1.0 CG3 Components
Figure 1
The CG3 consists of the following components, as shown in Figure 1:
1. CG3 taximeter display unit.
2. Cable and bracket assembly, with attached RS-232 serial cable and connector
(see Figure 2 below).
3. Seal-screw and hex-nut.
4. (Optional) USB mini-B adaptor.

1.1 A Note Concerning the RS-232 Cable Connector
In Figure 2, the connector shown above is a female connector which is used with
many third-party dispatch terminals, and was the original default option provided
with early models of the Record CG3. Nowadays, the CG3 comes with a male
connector by default for communicating with the BlackCat OBDII device for
measuring automobile speed.
If you require a female connector, please contact us for a male-to-female adaptor,
which we provide for a nominal cost, plus shipping.

2.1 Grounding
We recommend that you ground the CG3 taximeter at the automotive battery, in order
to:
properly detect the vehicle motion signal, and
to aid in ensuring that vehicle noise is not induced into the taximeter
motion circuit (from nearby circuits, motors, etc.).
This can’t be over emphasized. In our experience, 90% of problems having to do
with detecting motion signals and/or noise are directly attributable to where
the taximeter is grounded. Grounding the taximeter to the frame, body or some
other intermediary point raises the potential for two main difficulties:
1) By introducing a small, but significant circuit resistance at the motion
detection circuit within the taximeter. This interferes with the capability of
the taximeter to detect a signal that is often already low in voltage
strength.
1
2) By creating ground loop problems, which are essentially circuits of
electromagnetic signals (noise). By grounding the taximeter to an
intermediary point, you risk having the taximeter act as a path to ground
for this noise.
On the other hand, Grounding at the battery helps to isolate the taximeter from noise,
by ensuring that it is not sharing a ground with other circuits. By grounding the

We have even encountered occasions where this small resistance produces voltage, which in turn generates current, which can then
flow back into the vehicle speed sensor, causing all sorts of problems such as improper automobile transmission shifting.

taximeter to the car battery, you effectively eliminate possible problems from
installation onward.

.
Finally, while the taximeter does provide filtering of noise signals (see section’s 4.4.6,
4.4.7 and 4.4.10 for more information), it is our experience that grounding to the
battery is your best protection against noise being interpreted as motion signals, and
ensuring that the proper motion signal is detected.
If by chance, you still encounter noise issues with your installation (i.e. the taximeter
registers distance while the vehicle is stationary) we have an inexpensive signal
conditioner device that will help you clean up and/or detect very weak signals. If this
is something that you require, you may call us or go to our website to purchase the
device:

be used to help detect weak signals.
2.2 Vehicle Speed Signal (VSS)
The CG3 will detect motion signals with the following minimum strength:
1) Analog (sine-wave): 700 mV peak-to-peak
2
Often, where the taximeter has been grounded to the frame or body, the taximeter will appear to operate fine in
the early going, but as time goes on, mileage-detection deteriorates.

6
2) Digital (square-wave): 300 mV peak-to-peak
Also, the taximeter will detect signals with frequencies up to 15 kHz (15,000 cycles,
or, pulses per second). Signals that are weaker than the parameters above can still be
detected with the help of our Signal Conditioner (see above).
2.3 DC Power Requirements
The Record CG3 requires a minimum of +5 Volts DC to operate. Further, the built in
voltage-regulator and surge-suppression will ensure that over-voltage or over-current
conditions will not interrupt its operation.
2.4 Fusing
As mentioned above, the taximeter has a built in power regulation. However, we
recommend that you still provide in-line fusing for the roof-light circuit, as the
taximeter does not provide protection. For bulbs, you should use a 3 Amp in-line
fuse, connected between the ignition/accessory power and the CG3 Green
wire. For LED top-lights a maximum of 1 Amp fusing should be used.
2.5 Relays
Internally, the Record CG3 has a large transistor sufficient to switch bulb or LED roof
lights without issue, and provides sufficient protection for the taximeter with regards to
large surges in electrical current. However, we see in odd occasions where, despite our
best efforts and recommendations, the internal transistor is somehow damaged and no
longer able to switch the roof light state. This results in downtime for the user where
they are required to send us the taximeter for repair.
To eliminate this possibility from happening, we recommend using an external relay for
switching the roof light circuit, particularly when using bulbs.
Further, some customers require compatibility with third-party dispatch systems that
require a +12Vdc signal to be provided externally whenever the taximeter is in the
HIRED state. Such configurations will require a SPDT type relay for providing a
signal which is inverse to the state of the roof light (which is off when the taximeter is
HIRED).
In either case, a good candidate relay is the Cole-Hersee RC-400112-NN, which can
be purchased either from us or from multiple third-party dealers.
