Use the extended-local I/O cables. These cables have a single-end

connector on one end and a dual-end connector on the other. The

maximum cable length for an extended-local I/O system is 30.5 cable-m

(100 cable-ft). Connect extended-local I/O adapters by using any of these

cables (Table 2.B):

Cable Length: Catalog Number:

1 m (3.3 ft) 1771-CX1

2 m (6.6 ft) 1771-CX2

5 m (16.5 ft) 1771-CX5

Important: You cannot connect or splice extended-local I/O cables to

form a custom cable length. For example, if you have a distance of four

meters between two extended-local I/O adapters or between a processor

and an extended-local I/O adapter, you cannot connect two 2-m cables

together. You would have to use the 5-m cable and have the extra meter

as slack.

You must set switches on the extended-local I/O adapter module. For

information, see its installation data, publication 1771-2.200.
