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.

Interfaces

Q:
How does the keyboard wedge work?
A:
The
keyboard wedge interface is a chain, like daisy-chaining
(e.g. SCSI), or serial pass-thru. It does not require a
terminator or terminating device at the end of the chain
(the farthest device from the keyboard port). The last
device on the chain can be a keyboard wedge device or a
standard AT keyboard. This type of keyboard can only exist
as the last device on the chain. Keyboard wedge devices
are generally input devices such as keyboards, bar code
scanners, and magnetic stripe readers (MSRs). Each device
acts like a keyboard and sends the same keyboard scan
codes to the computer. Because of this, no driver is
required; everything is controlled by hardware. If any
device on the chain is locked, such as a Posiflex keyboard
on L0, that device and all devices after it on the chain
(farther from the computer) will be disabled. To use these
devices set the key position away from L0 (LP or L1-L4).
See also “How does the serial pass-thru work?”
Q:
How does the serial pass-thru work?
A:
Serial pass-thru is a chain interface, like SCSI or
keyboard wedge. It requires a terminator or terminating
device at the end of the chain (the farthest device from
the COM port). Pass-thru devices are usually output
devices, and the choice of destination is controlled by
pass-thru codes sent to all the devices before (closer to
the COM port than) the destination device. Then those
devices with pass-thru enabled will filter incoming data
for the code to disable pass-thru, and if that code is not
received, the data will be sent to the next device in the
chain until it reaches a device without pass-thru enabled.
Cash Drawers (CR3xxx)
Q:
My cash drawer won’t open!
A:
That’s not even a question.
Q:
Okay, why doesn’t my cash drawer open?
A:
Make sure it’s not locked. For computer-controlled
opening, the key must be in the middle position (up). Then
check the cable connection. Then make sure it works. Try
going to the DOS prompt and kicking it out manually. Set
the port settings using MODE:
mode com[n] 9600,n,8,1
where n is the
COM port number (1 through 4). If the drawer is connected
to the CR, CR1, or CR2 port of a Posiflex terminal, use
COM1:
mode com1 9600,n,8,1
To send the
opening code, use the ECHO command, send Ctrl-G, and
redirect it to the COM port:
echo ^G>com[n]
where you would
hold Ctrl and press G for ^G. Again, for COM1 or CR1, use:
echo ^G>com1
If the drawer is
connected to CR2, use code ^W:
echo ^W>com1
