UBI EasyCoder 501 – Technical Manual
Connector configuration
The connector is the standard female 36-pole Centronics type. The
mounting holes are connected to chassis ground.
Note:
The PE signal (Paper End) on pin 12 requires an error-trapping
routine to be included in the UBI Fingerprint software, activating
the
BUSY
and
READY
statements. Here is an example on how such
a routine may be written:
10
IF (PRSTAT AND 4) THEN GOSUB 1000
20
IF (PRSTAT AND 4) = 0 THEN GOSUB 2000
. . . .
. . . .
. . . .
1000 BUSY4
1010 RETURN
2000 READY4
2010 RETURN
Also see
BUSY
and
READY
statements and
PRSTAT
function in the
UBI Fingerprint manuals.
