ALSO IT IS RECOMMENDED TO MAKE ANY
NECESSARY CONNECTIONS INSIDE THE
CABLE CONNECTOR TO BE MOUNTED ON
THE CMM. IT IS NOT RECOMMENDED TO
USE TERMINAL STRIPS OR OTHER TYPES
OF CONNECTORS ALONG THE LENGTH OF
THE TRANSMISSION LINE.
NOTE
WHEN WIRING RS-422 /485 MULTIDROP CABLES,
REFLECTIONS ON THE TRANSMISSION
LINE CAN BE REDUCED BY CONFIGURING THE
CABLE IN A DAISY CHAIN FASHION AS
SHOWN BELOW.
