Each PC Link Unit must be given a unit number. This number will determine
the LR words allocated to it. The Unit assigned number 0 is the polling unit.
All other Units are polled units. Do not use the same unit number more than
once in any one Subsystem. Do not set a number higher than one less than
the maximum number of PC Link Units allowed in the System. Remove the
DIP switch cover with a screwdriver and adjust the DIP switch according to
the following tables. Confirm that all switches have been properly set and
that the PC power is off before mounting the PC Link Unit to the PC. Exam-
ple DIP switch settings are presented at the end of this section.
