Main Connector
SBG Systems has selected a specific connector designed for high reliability. The main connector provides access to all Pulse-20 features through a modular way. It provides:
The main serial port (PORT A) that supports full-duplex communication. It operates in RS-
One CAN 2.0A/B connection that supports up to 1 Mbit/s data rate used to output data
The table below give manufacturer and model number of the recommended mating connector.
