Matchcode
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 scanner 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: Some applications require the line worker to change the master symbol.
This can be done by installing a switch at the location of the scanner. 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 scanner to record the next decoded symbol(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.
