INSTALLATION

MODULE LAYOUT
The module has three ports at the bottom of the enclosure. The ports are used for Ethernet,
RS232 serial, and power.
The power port uses a three-way connector which is used for the DC power supply; positive
and negative (or ground) voltage, as well as the earth connection.
The RS232 port uses a four-way connector. This provides connection for the communication
transmit (TX), receive (RX), and ground (GND) conductors. The fourth connection is used for
shielding the cable in high-noise environments.
The Ethernet cable must be wired according to industry standards, which can be found in the
additional information section of this document.
