RB – Packetization Threshold : Set/read character threshold. RF
transmission is begun after receiving RB bytes, or after receiving at
least 1 byte and seeing RO character times of silence on the UART.
RO – Packetization Timeout
: RF transmission begins after receiving
RB bytes, or after receiving at least 1 byte and seeing RO character
times of silence on the UART. If RO=0, then RB bytes must be received
before beginning transmission.
RANGE: 0x0 to 0xFFFF.
PK – Maximum RF Packet Size
: Set/read maximum RF packet size.
Must be 256 (0x100) or less for 9600 baud RF rate (BR=0), and 2048
(0x800) or less for 115200 baud RF rate (BR=1).The range is 0x1 to
0x800.
CS – Pin 9 Configuration
: Select behavior of serial Terminal Block
position 9 (CTS). This is a pull down option. Selections are:
0 – CTS Flow Control
1 – RS-485 Enable Low
2 – GP01 Static High
3 – RS-485 Enable High
4 – GP01 Static Low
RT – Pin 10 Configuration
: Select function for serial Terminal Block
position 8 (RTS).
This is a pull down option. Selections are:
0 – Unused
1 – Binary Command Indicator
2 – RTS Flow Control
FL – Software Flow Control
: Select flow control options. Enables
software flow control (XON/XOFF) between radio modem and host. This
is a pull down option.
0 – No Software Flow Control
1 – Use Software Flow Control
FT – Flow Control Threshold
: Set/read the flow control threshold. De-
assert CTS and/or send XOFF when FT bytes are in the UART receive
buffer. The range is 0x0 to 0xFFFF.
