RS485 Bus Termination
Figure 12 - RS485 Bus Termination Jumper
The insertion of jumper J1 terminates the RS485 bus. This should be done only for
the last STAR-Box™ device in the network and bus termination should not be made
inside the STARGATE™ device.
CAUTION
In RS485 networks, the termination resistance must be enabled
ONLY on the last device of the chain, the farthest away from the
Host (assuming the Host is the first device of the chain). On all the
other devices this resistance MUST NOT be enabled (J1 open).
