Installation 2

The three basic communication connections for individual BASIC I/O ADs are:

Repeat

Used in RS-422 networks to extend range to 5000 feet between units. Sequential Display reads L1

Multidrop

Used in RS-422 or RS-485 networks.

Provides a total network range of 5000 feet.

Display reads L2

Last Unit

Must be used in RS-422 and RS-485 networks for the unit most distant from the host. Sequential display reads L3

If there is only one BASIC I/O AD in a network it is designated L3.

For the network layout, the sequential display indicates the letter “L” followed by “1", “2", or “3". As shipped, BASIC I/O ADs are setup as “l3", Last Unit. This parameter is not changed by push button but is displayed as “l1", “L2", or “L3" after the dip switches have been set and the unit has undergone a power cycle.
