Sequence Step
New Master Pin
After
New Master Pin has been enabled and the pin activated, decodes will be saved
in the master database beginning with master symbol #1. If the reader is configured
for a multisymbol read cycle (
Number of Symbols is greater than 1), the remaining
decodes will be saved in each consecutive master symbol location. For example, if
Number of Symbols is set to 3 and New Master Pin is then activated, at the end of
the next read cycle, the decoded symbols will be saved as master symbols 1, 2, and 3.
Usage:
Useful in applications in which it is desirable to count by intervals other
than 1.
Definition:
Sequencing in
Matchcode operations can occur in steps from 1 to
32,768.
Sequencing performs like a mechanical counter by displaying positive
integers and a specific number of digits after roll-overs. For example, 000
– 3 = 997 (not –3) and 999 + 3 = 002 (not 1002).

Default:

Options:
0 - 32768
Usage:
Some applications require the line worker to change the master symbol.
This can be done by installing a switch at the location of the reader. It is
very common to have a keyed switch so that accidental switching does
not occur.
Definition:
After
New Master Pin is enabled, a pulse can be received on the new
master pin which will cause the reader to record the next decoded sym-
bol(s) as the new master symbol(s).
It is important to note that the enabling
New Master Pin does not in
itself cause a master symbol to be recorded. The master pin must then
be activated momentarily (for a minimum of 10 mS) before a master
symbol can be scanned into memory. (See
"Electrical Specifications"
on page A-4.)
