Cabling
The host c ompu ter , ter minal, or point of sale
de vice is connecte d to the c ash drawer thr ough
a stan dard RS232 c able , the same as those
common ly use d to connect serial printers. Two
DB-25 connectors are provide d on the rear pane l
of the cash drawer – one male an d one fe male .
Either connec tor may be use d to communi cate
with the h ost de vice and the other may be used
to option ally connec t a printer or additional
drawers in daisy chain fashion.
Important Note:
The DB-9 connector is becomin g increasingly
popu lar as a re place ment to th e DB-25 conn ector
for serial por t applications. I f you point of sale
de vice uses th e DB-9 connec tor f or serial por t
output, it may be nec essary to obtain an adapter
to the D B-25 for m. Th ese can be purch ase d from
M-S C ASH DR AWER , your compu ter store , or an
electronics parts h ou se such as R ADI O SHAC K.
See Appen dix A f or dif ferences in pin-out.
4. Testing
A si mple operation al check of the KLI C interface
can be done in pu lse mode . Se t the switch bank s
for pulse mode an d apply a signal of 5 VDC to
12 VDC momen tarily between pin 2 (positive) to
pin 7 (ne gative ) of the interface cable . The
voltage source may be from th e compu ter buss or
simply a small battery. This check will test the
KLI C’s compu ter , power circuitry, sole noid driver,
as we ll as the dr awer circuitry. (Make sur e the
12 VDC plu g-in adapter is connec ted and
powered.)
Important Note:
Be sure to close the dr awer when perf or min g
tests. The KLI C interface is smart enou gh not to
energize the solen oid if the drawer is alr eady
open .
