The following info are provided absolutely "AS IS".
Warning: All commands to 710s are case sensitive, please do not try commands that you don't know, or it may totally ruin the device!
For USB models, the device can be accessed via the virtual COM port it connected to. For Ethernet models, the device can be accessed via port 10001 using TCP connection.
All commands should be started with a NULL (0x00) character.
Here are the commands we discovered

Returns "DATAQ" Returns Device name
Returns firmware revision
Returns SD operation flag (1 for scanning, 0 for not)
Returns device description
B 0...7 Baud rate selection, where 0 =4800, 1=9600, 2=19200, 3=38400, 4=57600, 5=115200, 6=230400, 7=460800. C 01...10 Set the number of channels D XX (the letter X) Read digital input if not scanning D 00...FF Set digital output d 00...FF Set digital port direction for corresponding bits (1 for input, 0 for output) F 0000....FFFF Set DAC0 output value f 0000....FFFF Set DAC1 output value L variable length The first two digits are the offset in scanlist, then 4 sets of scan configurations. For example
L030030FFF5680344040 will change the scanlist to
[unchanged, unchanged, unchanged, 0x0030, 0xFF56, 0x8034, 0x4040, unchanged....]
Each member of the scanlist is defined as
[000:Diff1:Gain4:Mux8]
Where a digital channel is enabled when Diff1=1, and Mux8=8. There is NO digital channel available in DI-148/158
M 0000....FFFF 16-bit sample rate divisor For DI-148/158, throughput rate = 14745600/divisor
For DI-710, throughput rate = NumberOfChannel*(14400/TimerScaler)/(NumberOfChannel+divisor)
N 0 Returns serial number + two digits to indicate PGA model S 0 1
Stop scanning Start scanning
T 0 Stop scanning X 00...FF TimerScaler for DI-71x's main 14400Hz clock. O 0 Read the real-time clock s 0 3
Stop recording to SD Start recording to SD
I yymm Update UTC Year/Month. No change is made to the clock yet J ddhh Update UTC Day/Hour. No change is made to the clock yet K mmss Update UTC Min/Sec, and apply all changes to the clock F X (the letter X) Format SD e 00000000....FFFFFFFF Specify an absolute address on SD m 0 Read 512 bytes from the SD, starting at the absolute address specified by e command Others Please do not try commands that you don't know, or it may totally ruin the device! A few of the above commands are used in this tech note
The data stream from DI-710 is like the following, which has three analog channels and a digital channel
