Connecting a Bus Stub to a Remote I/O Scanner

A bus stub must always be Belden 9182 or equivalent cable, regardless of the cable type used for the dual bus trunk.

BUS B

TERMINATING RESISTOR NEEDED IF REMOTE

I/O SCANNER IS AT END OF A BUS.

The total length of all stubs on a bus should be 100 feet or less. Within each 20% section of the actual bus length, the total maximum stub length is 20 feet. This can be divided into shorter stubs, provided that the total length in each 20% of the bus is 20 ft. or less.

1.Bus stub cable attaches to the upper four terminals on a Remote I/O Scanner.

2.Connect Serial 1 to Serial 1 of the next device. Connect Serial 2 to Serial 2 of the next device. Connect Shield Out to Shield In of the next device. Connect additional devices in the same way. If the Remote I/O Scanner is the bus switching device (directly connected to the dual bus), its Shield In terminal can be left unconnected. If it is the last device on the bus stub, the Shield Out terminal can be left unconnected. The bus stub does not require a terminating resistor.
