Protocol Commands

These commands can be used to tune the transceiver for optimum transmission of
data across the RF link. For most applications, the default values are adequate.

Command

Description

pe[?|0-4]

Set Alternative Frequency Band

0 = FCC/ETSI operation. (~2401 – 2471MHz) (default)

1 = France (~2448 – 2473MHz)

2 = Spain (~2448 – 2473MHz)

3 = Japan (~2473 – 2495MHz)

4 = Canada (~2452 – 2478MHz)

ph[?|00-fe]

(base only)

Set Hop Duration

90H = default (=10ms)

pk[?|00-d0]

Set Minimum Data Length

01 = default

pl?

Get Maximum Data Length

D4 = default (=212 bytes)

pn[?|01-3e]

(base only)

Set Maximum Number of Remotes

3e = default (=62 remotes)

pr[?|00-ff]

Set Packet Attempts Limit

10H = default

FFH = Infinite retry

(RF flow control point-to-point

nly)

pt[?|00-ff]

Set Data Transmit Delay

00H = default

pv[?|0|1]

(base only)

Set Slot Assignment Mode

0 = default (dynamic slot assignment)

1 = static slot assignment

pw[?|00-34]

(base only)

Set Base Slot Size

08H = default (=32 bytes)

px[?|0|1]

Set ARQ mode.

0 = ARQ enabled (default)

1 = ARQ disabled (redundant transmission)

Note: Incorrect setting of these parameters may result in reduced throughput or loss of data
packets.
