7.8 Data transmission RS interfaces
Two interface cards are available for data transmission in the UREG200, one RS232
interface (type code -1) or one RS485 interface (type code -2). Two major
considerations should be made when selecting the interface.
1. how many participants do I want to connect?
-
For more than one participant
→ RS485
-
For one participant
→ RS232 or RS485
2. how long is my overtagging distance?
-
Over 20m line path
→ RS485
-
Up to 20m line path
→ RS232 or RS485
