What is the number of

channels? in the General
screen
3
Controls both ALTGX
instance 1 and ALTGX
instance 2.
What is the starting channel
number? in the Reconfig
screen
Set this option to 0
The logical channel
addresses of the first to sixth
channels are 0, 1, 2, 3, 4, and
5, respectively.
Because the starting channel
number increments in steps
of 4, you must set the
starting channel number of
the next ALTGX instance as a
multiple of 4. Therefore, set
this option to 8.
The logical channel
addresses of the first to third
channels are 8, 9, and 10,
respectively.
For more information, refer
to Table 2–16 on page 2–37
for the ALTGX_RECONFIG
instance 1 settings.
1 For Case 2, do not set the What is the starting channel number? option to 4 for
ALTGX instance 2 (as in Case 1) because the logical channel addresses 4 and 5 are
used already for the fifth and sixth channels of ALTGX instance 1. Instead, use the
next multiple of 4 to assign it as the starting channel number of ALTGX instance 2.
