Extended System-Level Command Functions
66
(GE) GPIO Equipped – This command is used to interface the printer to external
controlling devices (see Appendix J):
Value
Units /
Interpretation
GPIO Enable Definition
A Applicator
Enables the standard applicator mode, de-asserting DRDY
as soon as last label starts printing, allowing FEED any
time, and not de-asserting DRDY when PAUSED.
N Disabled Disables the GPIO Port.
V Verifier Enables the GPIO Port for a bar code verifier.
2 Applicator2
Enables the alternate applicator mode, where Data Ready
(DRDY) is extended to overlap the End Of Print (EOP) signal
by about 1 msec when printing the last label; and, where
PAUSE or FAULT de-asserts the DRDY signal and inhibits
the FEED operation.
(GM) Gap / Mark Value – This command sets threshold value for the media
sensor’s “gap” or “mark” parameter.
(GP) GPIO Error Pause – This command enables or disables the printer from
sending a service required fault to the GPIO output (Applicator Interface CCA, Type 2
only).
(GR) Gain Reflective Value – This command sets the sensitivity of the reflective
media sensor.
(GS) GPIO Slew – This command sets the GPIO slew function and control:
Value Slew Interpretation
0 Standard (Active Low)
1 Low Pulse *
2 High Pulse *
3 Slews while low (Active Low)
4 Slews while high (Active High)
* Pulse must be at least 60 milliseconds in length; functions as if pressing the Feed Key,
clearing alarms and advancing media.
