2.10 95T GPI BR Bridge.
The 95T GPI BR Bridge interface is used to connect two RS485 buses together ( see system diagram for
Multi-reader Systems chapter 1.2.2).
Connections:
The Bridge will always have address 00 on the second bus (Lower level).
Important note:
The Bus above (bus 00) and the bus below (bus xx) must
not
have the same 0 V. The
Bridge makes a galvanic separation (opto-coupler) between the 2 bus systems. If the 0 V from the 2 bus
systems are connected together it will create earth loops which can give electrical noise problems.
