This is the KEETEC TAXI CAN v1 CAN-Bus Speed Pulse Generator

Please see below for further details:

The KEETEC TAXI CAN is an electronic module designed to read the current vehicle speed through OBD2 and transform it into PWM signal which is used as input signal for taximeters.

Current speed of vehicle is converted from km per hour to impulse per second in three ratio of conversion.
Moreover, the TAXI CAN module provides information about status of ignition* and low speed status signal. A detailed list of analog outputs can be found in the instructions for use.

* Information about ignition is based on the OBD2 communication through the vehicle data link. The module connects to the ignition and the communication control is carried out within approximately 2 s after the power supply is activated, the activation of the output is slightly delayed. Therefore, the possibility to use this function must be verified on a particular vehicle!

Note: The module connects to the ignition of the vehicle.

Technical parameters:

• range from 0 to 254 km/h
• it is possible to choose from the 1800 impulses, 3600 impulses or 7200 impulses per km
