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)

Byte1	0	A5	A6	A7	A8	A9	A10	A11
Byte2	1	0	D_in	A0	A1	A2	A3	A4
Ax is the xth bit of the ADC reading. D_in is the digital input bit. Sample rate = baud rate/24.
