Notes for connecting the RS-232 communication cable:
• Connect the shield to the ground of the host (PC). Usually, this connection is soldered
internally inside the connector at the PC end. You can use the drain wire to facilitate
connection.
• The RS-232 communication port is non-isolated.
Ensure that the shield of the cable is connected to the shield of the connector used for RS-232
communications. The drain wire can be used to facilitate the connection.
