CAS NT-302A - Current Loop Interface; Communication with Other Devices; Current Loop Circuit

35 / 44
4. Current Loop Interface
“Current Loop” Interface is stronger for Electric Noise than “RS-232C” interface.
So, it can be used for long distance communication.(About 100m long distance).
※ Current Loop Interface supports, up to 9,600 Communication Speed, only.
1. Signal Format
As same as “RS-232C” Interface
