NOTES
MSW 8-5:
When Off is selected, a bit of the “paper end sensor” in each status that is transmitted from the printer is
changed every time the rear cover is open or closed. When On is selected, a bit of the “rear cover open /
close" in each status that is transmitted from the printer is changed every time the rear cover is open or
closed. When you replace a SRP-270 with a SRP-275II, you should adjust the MSW 8-5 to Off.
MSW 8-8:
When Off is selected, a bit of the “automatic recoverable error” in each status that is transmitted from
the printer is changed every time the rear cover is open. When On is selected, a bit of the “mechanical
error” in each status that is transmitted from the printer is changed every time the rear cover is open.

NOTES
There are two methods, DIP Switch and Memory Switch, to adjust the serial communication conditions.
DIP Switch 1-5 selects which is effective, DIP Switch or Memory Switch.
To enable the “Serial communication“ setting, you have to adjust the “Serial interface selection“ function
of DIP Switch 1-5 to “Memory Switch”.

3-2-1 Memory Switch setting for Star mode
•Settings
Memory Switches are from MSW 0 to MSW 8. They are stored in non-volatile memory (flash memory). To
change the settings, send the following commands from the host.
[Name] Set Memory Switch
[Code] ASCII ESC GS # m {n1 n2 n3 0n4}0... {n1 n2 n3 n4}8 LF NUL
Hexadecimal 1B 1D 23 m {n1 n2 n3 0n4}0... {n1 n2 n3 n4}8 0A 00
Decimal 27 29 35 m {n1 n2 n3 0n4}0... {n1 n2 n3 n4}810 0
[Defined Region] m = "W", "T", ",", "+", "-", "@"
"0" ≤n1,n2,n3,n4 ≤"9",
"A" ≤n1,n2,n3,n4 ≤"F"
[Function] Sends command to write after defining Memory Switch using the definition command
specified by the following classes to set the Memory Switch. The printer is automatically
reset after writing the setting defined by that command to the non-volatile memory.
Do not turn off the power to the printer while sending commands to the non volatile
memory. Doing so will destroy the Memory Switch setting. It is also possible for all Memory
Switch settings to become offset to their initial, default settings.
Consider the life of the non-volatile memory and avoid over-use of this command.
