Extended System-Level Command Functions
Class Series 2 Programmer’s Manual 69
(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.
(GL) Gap Sensor Location
(MP Compact4 Mark II only)
– This command will tell the
printer which sensor to use when GAP mode is selected either by the <STX>KcSTG;
or by <STX>e. Outer Gap sensor is defined as the sensor 6.3mm from the edge of
the media, (Outer is default). Inner Gap sensor is defined as the sensor 17.2mm
from the edge of the media
(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.
