SHORT DESCRIPTION OF DATA TRANSFER BUS
CAN2.0
For the operation of the RC panel, an advanced CAN2.0 standard
interference-free bus is used. According to CAN2.0 standard, the signal cable
length may reach the above one kilometer values. However, the correct operation
at such distances depends on many factors.
At distances above 25 m – using of Cat5e or Cat6 twisted pair is obligatory.
The total DC resistance of the RC panel
power supply wire shall not exceed 50 Ω.
In case this requirement fails to be met where the panel is installed, an
auxiliary 12V/100мА PSU (RC panel’s minimum operating power supply voltage is
7.5V) can be installed. At that, 3 wires from the turnstile – CL, CH, GND - are
sufficient for correct operation.
Two panels can be connected to one turnstile.
The available 120 Ω resistors on the bus ends is the essential feature of
CAN2.0 bus. Such resistor has been already installed in standard RC panel.
