Connector J1

1

CH1

Chassis connection 1. One of two independent connections to Chassis.

2

CH2

Chassis connection 2. One of two independent connections to Chassis.

Note: Signals CH1 and CH2 should have independent connections to Chassis. The SIM100 module continuously

monitors continuity between these two signals. This information is used for examination of the assured connection of

the SIM100 module to Chassis. Absence of solid Chassis connections is reported as a Fault; at that time the results of

the Isolation Measurements are not valid.

Connector J3

1

V

X1

To be connected to positive terminal of the Battery. The two pins in this

connector are shorted on the PCB; either one or both (redundant) pins can

be used for the electrical connection.

2

V

X1

Same as above.

Connector J4

1

V

X2

To be connected to negative terminal of the Battery. The two pins in this

connector are shorted on the PCB; either one or both (redundant) pins can

be used for the electrical connection.

2

V

X2

Same as above.

Connector P1

1

VCC

Positive power supply, can be any voltage within +4.8 V to +53 V.

2

CAN_L

One of two CAN communications lines. Termination resistor of 120 Ω is

installed between these two lines on the SIM100 module.

3

CAN_H

One of two CAN communications lines. Termination resistor of 120 Ω is

installed between these two lines on the SIM100 module.

4

GND

Common / GND connection, negative return for the power supply.

Note: Signal names for pins of connector P1 are labeled on the PCB. Signal GND is galvanically isolated from Chassis.
