GU-3900B series “General Function” Software Specification
4.7.4.69
US ( e 40h a [b c ]
(Display status send)
Code:
1Fh 28h 65h 40h a [ b c ]
Definable area:
a = 01h:
Boot version information (b, c not used)
a = 02h:
Firmware version information (b, c not used)
a = 10h:
2-byte character code information (b, c not used)
a = 11h:
Language type information (b, c not used)
a = 20h:
Memory checksum information
00h ≤ b ≤ FFh: Start address (Effective address = b×10000h)
00h ≤ c ≤ FFh: Data length (Effective data length = c×10000h)
a = 30h:
Product type information (b, c not used)
a = 40h:
Display x dot information (b, c not used)
a = 41h :
Display y dot information (b, c not used)
Function:
Send display status information.
The following data is transmitted from the RS-232 interface:
This command is valid in both User setup mode and Normal mode.
4.7.4.70
US ( i 10h a b
(RS-232 serial settings)
Code:
1Fh 28h 69h 10h a b
a:
Baud rate setting
b:
Parity setting
Definable area:
00h ≤ a ≤ 0Bh
a=00h: 19200 bps
a=01h: 4800 bps
a=02h: 9600 bps
a=03h: 19200 bps
a=04h: 38400 bps
a=05h: 57600 bps
a=06h: 115200 bps
07h ≤ a ≤ 0Bh: Setting prohibited
00h ≤ b ≤ 02h
b=00h: No parity
b=01h: Even parity
b=02h: Odd parity
Function:
Change the RS-232 serial interface communication parameters.
Operation is [DTR=MARK][Communication settings change][DTR=SPACE], so do not send the next
data until DTR=SPACE.
If unsent data is in the transmit buffer (due to DSR=MARK), this data may not be transmitted
correctly, so ensure the transmit buffer is clear before issuing this command.
For baud rate setting a = 07h – 0Bh, display operation is not guaranteed. Do not use this setting.
4.7.4.71
FS | M m d1...d6
(Memory re-write mode)
Code:
1Ch 7Ch 4Dh m d1 ... d6
Definable area:
m = D0h
d1...d6 = “MODEIN”
Function:
Shift to “Memory re-write mode” from “Normal mode”.
Memory re-write mode is used for changing the firmware and fonts, etc in FROM that cannot be
changed in User setup mode.
Changing this FROM requires special commands and tools.
Do not use this command.
