3.8  INSTRUMENT : NETWORK MENU

A. 

Items in the Network menu include Protocol, Address and Baud Rate

B. Protocol: 

This is the data format for communication between the unit and the host 

computer. Available values are SPI CCP, Modbus RTU and CAMAC. SPI is the standard 

Society of Plastics Industry, Inc. protocol. CAC is the CAMAC protocol used on older 

Milacron machines. Modbus RTU is used in serial communication and is a common serial 

communications protocol for industrial equipment.
