All bytes are converted to ASCII:
number of samples<CR>
channel mask<CR>
DIO data<CR> (If DIO lines are enabled<CR>
ADC channel Data<cr> <-This will repeat for every enabled ADC channel<CR>
<CR> (end of data noted by extra <CR>)
When operating in API mode (AP > 0), the command will immediately return an ‘OK’
response. The data will follow in the normal API format for DIO data.
IT (Samples before TX)
Command
<I/O Settings> The IT command is
used to set/read the number of
DIO and ADC samples to collect
before transmitting data.
One ADC sample is considered complete when all enabled ADC channels have been
read. The module can buffer up to 93 Bytes of sample data. Since the module uses a
10-bit A/D converter, each sample uses two Bytes. This leads to a maximum buffer
size of 46 samples or IT=0x2E.
When Sleep Modes are enabled and IR (Sample Rate) is set, the module will remain
awake until IT samples have been collected.
IU (I/O Output Enable) Command
<I/O Settings> The IU command is
used to disable/enable I/O UART
output. When enabled (IU = 1),
received I/O line data packets are
sent out the UART. The data is
sent using an API frame
regardless of the current AP
parameter value.
KY (AES Encryption Key)
Command
<Networking {Security}> The KY
command is used to set the 128-
bit AES (Advanced Encryption
Standard) key for
encrypting/decrypting data.
Once set, the key cannot be read
out of the module by any means.
