Default
KY
AES Encryption Key
. Sets the 16 byte network security key
value. This command is write-only; it cannot be read. Attempts
to read KY will return an OK status. This command parameter
must be set the same on all devices for communication to
work. This value is passed in as hex characters when setting
from AT command mode, and as binary bytes when set in API
mode.

BD
Baud Rate
. The serial baud rate of the XLR PRO. This value only
affects the interface data rate for RS-232 and RS-485/422 data
through the serial port. Values from 1-9 select preset standard
rates. The values from 1 to 9 are interpreted as follows:
1
- 2,400b/s
5
- 38,400b/s
9
- 480,600b/s
2
- 4,800b/s
6
- 57,600b/s
3
- 9,600b/s
7
- 115,200b/s
4
- 19,200b/s
8
- 230,400b/s
If a non-standard baud rate is needed, a value above 0x5B9 can
be entered to select a specific baud rate. The BD parameter will
adjust to the closest supported baud rate if a non-standard
value is entered. After entering the specific baud rate, BD can be
queried to read the actual baud rate. Baud rates can go as high
as 6Mb/s, but the host and serial switching circuitry may not
support it.
1 to 9, and 0x5B9
to 0x5B8D80
3 (9600 b/s)
NB
Parity
. Set or read parity settings for serial communications.
The values from 0 to 2 are interpreted as follows:
0
No parity
1
Even parity
2
Odd parity
0-2 0
(No
parity)
SB
Stop Bits
. The number of stop bits for the UART.
0
- One stop bit
1
- Two stop bits
0-1
0
RO
Packetization Timeout
. The number of serial character times
of inter-character silence required before packetization in
transparent mode. Set (RO=0) to transmit characters as they
arrive instead of buffering them into one RF packet.
0 - 0xFF
