CG3 Setup Instructions
Figure 1
The CG3 consists of the following components:
1.
CG3 taximeter display unit.
2.
Cable-and-bracket assembly, with attached RS-232 Serial communication cable.
3.
Seal-screw and hex-nut.
4.
(Optional) USB mini-B adaptor.
Figure 2: D9 Serial Connector. Used for RS-232 communication. You will need a male 9-pin
Connector if you are using a Black Cat adapter for sensing motion, or a female connector if you are
communicating with most Dispatch Terminals (MDT). IMPORTANT: See section 2.2

  • Page 2 IMPORTANT: While the CG3 Taximeter does contain internal protection against most catastrophic high-current instances, some precautions still need to be taken by the operator to protect the CG3 Taximeter roof light circuit against unforeseen extreme current surges that can occur in the often hostile automotive environment (with regards to sensitive electronics).

    To activate the Config Switch, you have to short the two plated holes together. This can be done, either with a programming pin (these are usually provided with CG3 upon purchase), or simply with a piece of wire (we find that a paper-clip works the best).

By default, the security code is 0: Figure 5: The Security Code Prompt, which locks against proceeding to programming mode when an optional security code has been previously set. If no passcode has been set, simply press to proceed to Section 4.0: Programming Menu.

    Calibrating Mileage This section is required if you are using Vehicle Speed Sensor (VSS) pulses to provide distance to the CG3 (as opposed to an OBDII interpreter device).Enter Configuration Mode (see section 4.4.1), and press...
  • Page 9 Set the Filter Value Upon entering Calibration Mode, you will first have the option to set the filter value, F1 (figure 15). The filter value is a feature that allows for re-sampling of individual mileage pulses to ensure that they are not noise “spikes” that could be interpreted as valid VSS pulses.
  • Page 10 Set the Signal-Conditioner Value (VSS Sensitivity) CG3 models with serial number 31,000 and up have a built-in signal conditioner that allow for adjusting the sensitivity of the VSS detector circuit. This is helpful in either eliminating noise which can lead to improper readings (i.e.

    View / Manually Set Calibration Value Next, the current calibration setting will be displayed (figure 16). You have the option to: a) manually change the current calibration setting, or b) skip changing the calibration value (in order to proceed to the calibration procedure).
