• If the settings are changed, they become effective when the BA-T500 is reset other power is turned
on again.
• The setting values can be checked by executing the self-test.

[Function] Sends the setting values of the memory switch specified with a
The contents of the transmit data are as follows:
Transmit data Hex Decimal Number of data
① Header 37H 55 1 byte
② Flag 21H 33 1 byte
③ Data 30H, 31H 48, 49 8 bytes
④ NUL 00H 0 1 byte
Contents of data shown in ③ above:
The on/off setting of the memory switch is defined as [Off: Hex=30H/Decimal=48] or [On: Hex=31H
/ Decimal=49]. Each 1 byte for 8 memory switches are transmitted from bit 8 to bit 1.
Example: Transmitted data: “10110001”
(31H, 30H, 31H, 31H, 30H, 30H, 30H, 31H)
Switch No. 8 7 6 5 4 3 2 1
Status On Off On On Off Off Off On
• If an unsupported memory switch number is selected, this command is ignored.
• If this command is ignored, the printer doesn’t send any data.
