SW4 – Switches 1,2, 4-6
These switches are reserved for Technical Support personnel.
Do not use.
SW4 - Switch 3
Switch 3 on SW4 is used for signal termination for Port 0 on the
PB3. Termination is important whenever multiple PB3 units are
interconnected via the unit’s built-in RS485 network and the
length between the PB3’s is more than 2000 feet. The default
termination setting on the ProBridge 3 unit is with termination set
to OFF. Whenever there are more than two PB3’s, termination
on some of the PB3 units will change. The first PB3 and the last
PB3 on the RS485 network will have termination set to ON
(Down), all others between these two units will have their
termination set to OFF (Up).
SW4 - Switches 7-8
Switches 7 and 8 on SW4 controls the Network protocol of Port 1
on the PB3. In other words, Port 1 on the PB3 can communicate
as an RS232 or RS485 port depending on the needs on the
Network environment.
