7.7.1.1 Entering SID and Zone Numbers
The "SID" number cannot be changed and always shows as zero on the RDU. The left and
right arrow keys are used to move the cursor between the start zone and end zone fields.
The SET key is used to swap the cursor between the top and bottom line of the display. The
zone numbers are entered on the top line and the LED numbers are entered on the bottom
line. Zone numbers must be in the range 1 to 528.
When some, but not all, of the specified zones are already present in the database, then the
bottom line of the display indicates this with a "split range" (or "extend range") message as
shown in the examples following. When an existing range is being split, the "non-visible"
part of the existing range that is being kept, has its LED numbers adjusted to match the
reduced size of the zone range. This adjustment should be checked to ensure it gives the
desired mapping.
7.7.1.2 Entering a New Zone Range
If none of the zones in the range specified by the start and end zone are present in the
database, then the bottom line of the display shows “Zones not present, press ACK to
assign”. For example :
SID:0 Start zone:31 End zone:40
Zones not present, press ACK to assign
Pressing ACK will add this zone range to the database. To assign a single zone, the start
zone and end zone should be the same value.
When the zones specified by the start and end zone correspond exactly to an existing entry
in the database then the bottom line of the display shows the current LED mapping for those
zones. For example :
SID:0 Start zone:1 End zone:1
Start LED :5 End LED :5
NOTE
in “view mode”, the cursor cannot be moved to the bottom line of the display.
If some of the specified zones are present in the mapping database, but do not correspond
to an exact entry in the database, then an appropriate message is shown on the bottom line
of the display as shown in the examples below.
For example, if the database contained the following entries :
Start zone 5, End zone 12
Start zone 13, End zone 20
If the start zone is now set to 5 and the end zone is set to 20, then the bottom line of the
display will show “ACK:Extend range ZONE:Show existing” even though all of the zones are
actually already in the database, and the LED mapping for zones in the range 5 to 12 might
be different from zones in the range 13 to 20.
Existing entries in the database can be modified (extended, split or deleted) as shown in the
following examples.
