Frequently Asked
Questions:
Commonly asked questions about APG, MMF, Logic Controls
and cash drawers in general:
Q: Why does the cash
drawer open with a key but does not open when using my software?
A: Make sure that your cash drawer is setup properly within
your software, the drawer will open on the bel character , ASCII (07) or
1C HEX.
Q: How can I test my
cash drawer to make sure it is working properly?
A: Go to a DOS prompt, and type the following command: echo
test^G>com1: or com2: or lpt1: ( the port you select has to be the
same port that your printer is on) [Enter].
Q: What do I do when
my CB-001 cash drawer does not open with a key and using software?
A: Sometimes in shipping, the money tray gets
wedged against the top cover. If you unscrew the 5 screws underneath the
drawer, the base will drop out and the money tray can be removed. Then
put the base back onto the cover, open drawer and place the money tray
back inside.
Q: I have a cash
drawer with a 12 (24) volt solenoid and a phone jack connector on the
end of the cable. How does this connect to my point of sale system?
A: The solenoid driven electronic cash drawers are individually
and specifically configured for a receipt printer interface. They are
non-intelligent drawers, totally dependent upon the printer to
"pop" them open when a receipt is printed.
Q: What are the "drawer
open" codes for my ECD 200 cash drawer?
A: The ECD 200 series are non-intelligent cash drawers, custom
wired for a specific 40 column receipt printer interface. The codes
required to "open the cash drawer" are printer codes found in
each printer manual. Example: Epson (RJ-11) HEX = 1B, 70, 0, 25, 250
ASCII = ESC, p, 0, 250
Q: Where are the "date of
manufacture" and "serial numbers" located on an MMF cash
drawer?
A: The numbers can be found on the "black and silver"
label located on the inside, front section of the cash drawer's chassis,
as well as on each shipping carton. Note: the inner drawer must be
removed to see it. On MediaPLUS drawers, just remove the tray as the
label is on the inner drawer
Q: Can I order additional
replacement keys for my cash drawer?
A: YES! MMF will custom cut any of their cash drawer keys. Call
to verify the "lock number" ( found on the face of each lock).
Master keys are also available for each series of locks. (exception;
MediaPlus).
Q: What are the electronic
specifications for an MMF 12 volt external power supply?
A: The correct power supply needed is a 117 volt, 60Hz,12 v.d.c.,
500 MA tip positive AC/DC adaptor
Q: I have a serial interface cash
drawer, with a 25 pin connector, but my COM port is a 9 pin. Can I use a
standard reducer?
A: NO! While a standard reducer, from 25 to 9 pin configuration
will transfer TXD and SG, it will not have the proper jumpers for
RTS/CTS and DSR/DCD/DTR, required for an MMF cash drawer.
Q: Do MMF cash drawers support
other interface connections besides "solenoid" or receipt
printer driven?
A: YES! The ECD 200 series has some basic characteristics. ECD
200 is printer driven. ECD 232ND is a "non-dedicated" or
addressable serial interface. ECD 232NP is a "No Power"
dedicated serial interface. ECD232 is a dedicated serial interface. ECD
230PL is a parallel interface drawer.
Q: My CR3001 does
not open from the SERIAL port through my application software.
A: Exit from your application software. Shell out to the MS-DOS command
prompt or restart computer in DOS mode.
At the DOS prompt, enter “MODE COMx 96,n,8,1” (excluding the
“” marks; x=1 or 2 depending upon which port you are hooked up to). On the next line enter “TYPE
CON>COMx”. After that,
on the next line hold down Ctrl and hit G. Then, hit Enter. The drawer should open if you
haven’t changed any of the default switch settings inside the drawer. If this still does not work,
make sure the switches are set to their default settings and that the
power supply adapter is working. If
you get a “Write fault error to COM port”, close any other software
that are set to use the same COM port and then try again (check
Autoexec.bat file to see if a LPT printer port is redirected to the COM
port).
If this test opened the drawer, go back to your application
software and check the port settings for COMx, 9600 baud, no parity, 8
bit data and 1 stop bit, and drawer opening code is Ctrl-G (hex 07). You may need to refer to your
software user manual or contact your software supplier for assistance.
Q: The cash drawer
sounds like it is trying to open, but it doesn’t open.
A: Make sure the lock is in the vertical position and
try again. If it doesn’t
open, use the key to open the drawer.
Slide out the cash tray and look inside. Check to see if there are
anything (coins or bills) blocking the solenoid at the back from moving
freely.
Q: What are the
control codes for opening a CR3000 printer driven drawer?
A: The control codes depends on model of printer
used. Refer to your POS printer manual for the correct command
code sequences. Following are examples for some common printers:
a.
Citizen IDP3540 / IDP3535
Star TSP2000 / TSP200 / SP312
Ithaca POSjet1000 / Model 181
Decimal:
07
Hexadecimal:
07h
ASCII Char:
^G (“Ctrl-G”)
b.
Citizen CBM1000 / IDP3210
Epson TM-U295 / TM-U200 / TM-L60II
Decimal:
27 112 48 55 121
Hexadecimal:
1Bh 70h 30h 37h 79h
ASCII Char:
^[ (“Ctrl-[“] p 0
7 y
Note that different POS software use different method for
entering the codes. Some
use 027 or \27 to enter decimal 27, some use 1BH, $1B, or &H1B to
enter hexadecimal 1Bh. Some
software use comma to separate entries, some just use a blank space to
separate entries. Refer to
your POS software manual or call your software vendor tech support for
the correct format.
Q: What is the CR3002 Self Powered Cash
Drawer?
A: Normally, a cash drawer needs power supplied
externally to open the drawer. The
power comes from the printer in case of CR3000 and from the AC power
adapter in case of CR3001. The
CR3002 is Logic Controls’ unique design “Self Powered” cash
drawer. There is no
external power supply needed and it connects to the DB25 serial port of
the computer directly. Power
is drawn from the COM port to open up the drawer. It can be opened with any
character send to the serial port and can use any communication protocol
with any bit rate from 150 bps up to 19.2K bps.
Q: The CR3002
opens through computer control at first trial but does not open the next
time. What should I do?
A: The CR3002 draws power from the COM port. Since the available power from
the COM port is very weak, it takes a few seconds for the cash drawer to
store up enough energy for kicking out the drawer. Wait for at least 5 seconds
before opening the drawer again.
Q:
I tested the CR3002 in DOS mode and it works beautifully. However, working with my POS
software, it doesn’t work. I
could hear a light clicking sound from the drawer each time I try to
open with the software but it just doesn’t pop out. What is the problem?
A:
Some Windows software keeps the
COM port closed all the time and only opens the COM port when trying to
send out data. Thus, the
CR3002 cannot get the necessary charging power. Make sure that the software
keeps the ports open all the time and have the handshake signals DTR and
RTS enabled.
Q:
I tried with the DOS functional test command to open the cash
drawer and get a “Write Fault Error”.
A:
There are several possible causes
to this problem:
a. Check
that no other software are set to use the same COM port. For example, you POS software
may be up and running, the UPS monitor software is resident, or the LPT
printer port is redirected to this COM port (check Autoexec.bat file).
b. Check
your connection to the PC, check that it is secure. Make sure the cash drawer is
connected to that port you used in the testing command.
c. Under
Windows, go to Control Panel -> System -> Device Manager. Double click on Ports, select
the port connected to the cash drawer.
Click on “Remove” to delete the port. Exit all Windows and restart the
computer. Windows should be
able to detect the port and set it up automatically. Shell out to DOS and try the
functional test again.
Q:
What are the default DIP switch settings for CR3001?
A:
Take out the cash tray and slide
out the drawer. Look inside
the drawer. At the back you
will see a printed circuit board (PCB).
On this PCB, you will see two switch blocks each with eight small
switches in a row.
The switch block on the left side should read from left to
right: Up Down Down Up Down Down Up Down.
This setting sets the baud rate to 9600 baud, no parity, 8 data
bits, 1 stop bit, Security Code Only mode. The switch block on the right
side should read: Down Down Down, Up Up Up Up Up. This setting sets the security
code to Ctrl-G (Hex 07).
Q:
I lost my drawer key, what can I do?
A:
For extra security reasons, Logic
Controls does not stock extra keys for the cash drawers. However, we do have some keys. So, give us a call. On the back or bottom of your
cash drawer is a number (Jxxx). Some
the drawers have the lock number imprinted on the lock itself. This number identifies your key. Give us the number and there
might be a slight chance we will have a particular key. If not, the key lock will have
to be replaced. Logic
Controls supplies each cash drawer with two keys. Be sure to keep at least one of
them in a safe place.
Q:
Does the CR3000 series cash drawers come with cables?
A:
The CR3000 comes with an
interface cable to plug into the kick out connector of your printer. When buying a CR3000, be sure to
specify which printer you will be using so that you will receive the
correct cable. Different
printers use different pin-out arrangements. You will also need to specify
the type of connector for connecting to the printer, they could be RJ11,
Molex, or BNC connectors.
The CR3001 comes with a serial interface cable to hook up your cash
drawer directly to the computer’s serial port. If you are planning to use the
cash drawer in a parallel interface configuration, you need to buy a
parallel straight through cable since it is not supplied with the cash
drawer.
The CR3002 comes with a serial DB25 to DB9 cable to connect your cash
drawer to the computer via the COM port.
Q:
Can I change the baud rate setting for the cash drawer?
A:
Yes, for CR3001, the baud rate is
user selectable via DIP switches located inside the cash drawer. The default baud rate setting
for CR3001 is 9600 bps, no parity, 8 data bits, 1 stop bit. The baud rate is selectable from
150 bps up to 19.2K bps. The
data bits are selectable between 7 and 8 bits string.
For CR3002, the drawer is able to work with baud rates from 150 bps up
to 19.2K bps automatically. No
setting is necessary.
Q:
Are Logic Controls cash drawers programmable?
A:
The cash drawers are
“programmable” in two ways. (1)
Signal Protocol. (2)
Security Code. If your cash
drawer is hooked up via the COM port, you have two options. The first option allows you to
change the security code to any ONE of the 255 ASCII characters. The second option allows you to
have the cash drawer open up with ANY character sent to it.
If your cash drawer is hooked up with parallel interface, you also have
the option to change the security code to any ONE of the 255 ASCII
characters. Parallel
connection does not have option to let ANY character to open the drawer.
