2. Confirm DIP SW 1-2.
Printer serial communication condition can be set by DIP SW and memory switch. When the
printer is powered on, DIP SW 1-2 selects DIP SW setting or memory switch setting as initial
communication condition. Selected setting is printed by self-test.
DIP SW1-2 OFF: Used communication condition set by memory switch.
3. Set communication condition
When DIP SW1-2 is ON
Follow the procedure (page 42) and set.
When DIP SW1-2 is OFF
Follow the serial communication conditions (page 44). There are two ways to set it. Refer to
"Memory Switch Settings" on page 44 or "Memory Switch Setting Utility" on page 91.
Note:
TM-L90 4** models or TM-L90 Peeler 39* models do not have the DIP switches; however, various
functions can be set with memory switches. For detailed information about the memory switches, see
"Memory Switch Settings" on page 44.
Q: Drawer Kick does not operate properly.
A: Drawer specifications differ depending on the manufacturer and the part number.
Refer to "Connecting to the Drawer" on page 74 and confirm connector pin assignments.
Make sure that the specifications of the drawer to be used meet the following conditions before
connecting it to the drawer kick connector. These conditions also apply to any other devices that
use the drawer kick connector.
Any devices that do not satisfy all the following conditions must not be used.
[Conditions]
• A load must be provided between drawer kick connector pins 4 and 2 or between pins 4
and 5. (*1)
• When the drawer open/close signal is used, a switch must be provided between drawer
kick connector pins 3 and 6. (*2)
• The input current must be 1 A or less. (*3)
NOTES
(*1) Operating the printer with incorrectly installed devices voids the warranty.
(*2) Connecting devices other than the drawer open/close switch voids the warranty.
(*3) Using with an input current of over 1A over current may cause a damage to the device.
Q: Unable to print a part of Page 0 (for example
A: When programming with Visual Basic, limitations prevent data from 81h through 9Fh and
E0h through FEh from being sent as characters. However, you can use the following
procedure to send this data.
Dim Send_ data(0) As Byte
Send_data(0) = &h81 '1 byte of sending data
MSComm1.Output = Send_data
