parameter is a non-zero value, the Config pin is configured as an output and set low

until the first RF packet is received. With a non-zero RP parameter, the Config pin is

an input for RP ms after power up.

RR (Retries) Command

<Networking & Security> The

RR command is used to set/read

the maximum number of retries

sent for a given RF packet.

When RR Command is enabled

(RR>0), RF packet retries and

ACKs (acknowledgements) are

enabled.

Exceptions: If the MT command in enabled (MT>0) or if a broadcast Destination

Address is used (DT = 0xFFFF); RF packet retries and ACKs are disabled.

After transmitting a packet, the transmitting RF module waits to receive an

acknowledgement from a receiving module. If the acknowledgement is not received in

the period of time specified by RN (Delay Slots) Command, the original packet is

transmitted again. The RF packet is transmitted repeatedly until an acknowledgement

is received or until the packet is sent RR times.

RT (GPI1 Configuration)

Command

<Serial Interfacing> The RT

command is used to set/read the

behavior of the GPI1 pin (pin 10)

of the OEM RF Module. The pin

can be configured to enable

binary programming or RTS flow

control.

SB (Stop Bits) Command

<Serial Interfacing> The SB

Command is used to set/read

the number of stop bits in the

data packet.
