Connectors

12min

Power

The voltage of the supplied power is 24V DC.

Due to a protection diode at the input, the 24V that is available on a number of connectors will be a bit lower, please check when connecting 24V devices to that connector if they will operate correctly.

Although the 24V is also available on the box header connectors, it is advisable to use separate wiring for powering 24V devices that exceed 50mA of required current.

Check the polarity of the power connections, damage to the board may occur if the polarity is reversed.

Network

The board needs to be connected via a CAT5 or CAT5E cross cable. We advise using properly shielded SF/UTP network cables. The default IP address is 172.22.2.100.

Document image


Make sure that the PC that the board is connected to is correctly setup and has the correct IP address, make sure there is no IP address conflict.

RS485

Via the RS485 connector external hardware can be connected. RS485 is a balanced signal, this decreases susceptibility to interference. The protocol that is used is MODBUS RTU.
