N Z   Return 10 bytes serial number of the device. If you run WinDaq, you can also inqure the serial number from the About dialog box
Send NULL before any command, which can be sent out by keying in <Ctrl-2> under VT100 mode if you are using HyperTerminal

DI-170 Encryption Table (T170)

Byte7 D11 D10 D9 D8 D7 Dig 0 0
Byte8 D6 D5 D4 D3 D2 D1 D0 1
Commands
Command (Binary) Dependence Action
1ccc cccc None Burst count = 1ccc ccccm ranging from 0x80 to 0xFF.
0000 0000 None No operation.
0001 0000 None Reset.
0001 1000 None Stop scanning.
0001 1001 None Start scanning.
0001 110d None Set digital output pin to state d.
01eb ChGa None Enable/Bipolar/Channel/Gain.
0001 0001 Stopped Inquiry
bit 7 = 1 is PGH (gain = 1, 2, 4, 8)
bit 7 = 0 is PGL (gain = 1, 10, 100, 1000)

bits 5, 4, 3 are the range index as follows:

   000:  ± 5V
   001:  ± 10V
   010:  ± 2.5V
   011:  ± 2.048V
   100:  ± 1.28V
   101:  ± 500V
   110:  Reserved
   111:  ± 100%
If all four channels are running, then
A = Channel 0, B = Channel 1, C = Channel 2, D = Channel 3.

If channels 0, 2, and 3 are running, then
A = Channel 0, B = Channel 2, C = Channel 3 (" D" group will not exist).

The throughput rate = 307200/(65536 - burst count × 256), except when the burst count = 0xFF, in this case the data throughput rate = 800

The sample rate per channel = throughput rate / number of channels

When the data throughput rate is lower than 600 S/s, the data transmitted through the RS-232 port will be spread evenly.

The default data throughput rate from RESET is 2.5 S/s

DI-180 Encryption Table (T180)

  B7 B6 B5 B4 B3 B2 B1 B0
Byte1 0 A5 A6 A7 A8 A9 A10 A11
Byte2 1 0 Din A0 A1 A2 A3 A4
Ax is the xth bit of the ADC reading.
Din is the digital input bit.
Sample rate = baud rate/24.
