DIP-switches 1, 2, 3, and 4 determine the machine number of the
VS-121HCA
.
DIP-switches 5 and 6 are not used.
DIP-switch 7 determines operation in tandem with the Kramer
VS-121HC
.
DIP-switch 8 determines the RS-485 bus termination for the
VS-121HCA
.
When several
product
units are connected, the machine number determines
the unique identity of the
VS-121HCA
in the sequence (see section
7.6
).
•
When using a standalone
product
unit, or when operating in tandem
with the
VS-121HC
, set the machine number to 1 (factory default)
•
When connecting more than one
VS-121HCA
, set the first machine
(only when connected via RS-232) to be machine number 1. The other
VS-121HCA
units must each be set to a unique machine number
between 2 and 16

connect to the PC, but each unit must be assigned a unique machine number.
