Ethernet port settings
Ethernet based communications have one setting for an IP Address in the format:
XXX.XXX.XXX.XXX:PPPP, where PPPP is the port number. The unofficial Port assigned for Modbus TCP is
502.
Serial Port settings
Serial port based communications have the usual settings which must be set to the same value as in the
communication device:
• COM Port – The PC COM port number or virtual COM port number.
• Baud Rate – Device Baud rate sets the data rate in bits per second.
• Stop Bits – Stop bits allow the receiver to synchronise with each data bit. Most applications only re-
quire 1 stop bit.
• Parity - the most common parity setting is "none", with error detection handled by the communica-
tion protocol.
• Number of Bits - 8 data bits is almost universally used in newer applications. Change your device to
8-bits if it is not already.
Note: For virtual COM ports the serial parameters are often set in the converter hardware. Alternatively they
may be set in Windows Control Panel. The most reliable method is to set the same parameters in PV
Clinics; Control Panel and the Converter driver (if possible).
