While CP202-2CI device connects with the CAN-Bus network via
twisted pair, CANL connects with CANL, CANH connects with
CANH. According to the ISO11898 standard, to reduce signal
reflections on the CAN-Bus and enhance the reliability of
communication, terminal matching resistor is usually added to 2
endpoints of the bus. The size of terminal matching resistor is
decided by the characteristic impedance of cable transmission,
such as twisted pair's characteristic impedance is 120Ω, the 2
endpoints on the bus should be connected 120Ω terminating
resistor. CP202-2CI can set external terminating resistor, when the
device is connected with the CAN-BUS network via a twisted pair,
only use resistor to short circuit between the twisted pair ports
RES+ and RES- to achieve terminal resistor accession, as shown
below.
When the CP202-2CI converter is used as the CAN-Bus network
terminal, the two pin is connected to a resistance of 120Ω,
otherwise no need to install a 120Ω resistor.

【Installation】
Before installation, confirm that the work environment meet the
installation require, including the power needs and abundant
space. Whether it is close to the connection equipment and other
equipments are prepared or not.
1. Avoid in the sunshine, keep away from the heat fountainhead or
the area where in intense EMI.
2. Examine the cables and plugs that installation requirements.
3. Examine whether the cables be seemly or not (less than 100m)
according to reasonable scheme.
- 3 -
4. Power: 9 ~ 24VDC
5. Environment: working temperature: -40～75℃
Storage Temperature: -40～85℃
Relative humidity 5%～95%
6. Support wall mounted
Wiring Requirements
Cable laying need to meet the following requirements,
1. It is needed to check whether the type, quantity and
specification of cable match the requirement before cable
laying;
2. It is needed to check the cable is damaged or not, factory
records and quality assurance booklet before cable laying;
3. The required cable specification, quantity, direction and
laying position need to match construction requirements, and
cable length depends on actual position;
4. Cables should be straight in the hallways and turning;
5. All the cable cannot have break-down and terminal in the
middle.
6. Cable should be straight in the groove, and cannot beyond the
groove in case of holding back the inlet and outlet holes.
Cables should be banded and fixed when they are out of the
groove;
7. User cable should be separated from the power lines. Cables,
power lines and grounding lines cannot be overlapped and
mixed when they are in the same groove road. When cable is
too long, it cannot hold down other cable, but structure in the
middle of alignment rack;
