Chapter 5: Programming 5-37
Check Digit
The Check Digit parameter permits you to control the transmission of
UPC-A, UPC-E, EAN-8, and EAN-13 check digits. Scan the appropriate
Hex
0 through Hex 3 tags to enable or disable UPC-A, UPC-E, EAN-8,
and EAN-13 check digits. The default is Enable UPC-A, EAN-8, and
EAN-13 and Disable UPC-E. This option also affects OCIA Long on
later versions of the firmware (497-0301339 and higher).
Retransmit On ACK Timer Expiration
This parameter is used with the Interface Control ACK/NAK
parameter to cause the 7892 scanner to automatically resend the
message to the host terminal or PC when the ACK Timer has expired.
Scan the Hex 0 tag to disable the Retransmit On ACK Timer Expiration
option, or scan the Hex 1 tag to enable it. The default is enabled.
Parameter Shortcuts
The RS-232 Parameters - 2 Programming mode contains four shortcuts:
A, B, C, and D. After entering this programming mode you can go
directly to a specific parameter by scanning the appropriate shortcut
Hex tag (Hex A through Hex D). This eliminates the need to enter all
parameters when only one needs changing.
