Brief description of CAN2.0 data bus
A modern noise-resistant CAN2.02 standard bus is used for UCP 02
operation. Correct operation depends on many factors.
For distances more than 25 meters, it is mandatory to use a Cat5e or Cat6
twisted pair. Total electrical resistance of CP DC power supply wire should not
exceed 50 Ohms.
If this requirement cannot be met, additional 12V/100mA PSU can be
installed at the CP place (minimum operating voltage of PSU is 7.5 V). At the
same time, 3 wires from the turnstile (CL, CH, GND) are enough for correct
operation.
Two control panels can be connected to one turnstile.
An important feature of the CAN2.0 bus is the presence of 120 Ohm
resistors at the ends of the bus. In a standard CP, such a resistor is already
installed.
