5.3.  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-B]
Set Alternative Frequency Band
0
 = USA operation.  (~2400 – 2472MHz) (default)
1
 = ~2448 – 2474MHz, avoids 11b channels 1 – 6 & 14
2
 = Spain (~2448 – 2474MHz), avoids 11b channels 1 – 6 & 14
3
 = Japan (~2471 – 2497MHz), avoids 11b channels 1 - 10
4 = Canada (~2452 – 2477MHz), avoids 11b channels 1 – 6 & 14
5 = ~2400 – 2425MHz, avoids 11b channels 6 - 14
6 = ~2409 – 2435MHz, avoids 11b channels 8 - 14
7 = ~2419 – 2445MHz, avoids 11b channels 1 & 10 – 14
8 = ~2430 – 2455MHz, avoids 11b channels 1, 2 & 12 – 14
9 = ~2440 – 2465MHz, avoids 11b channels 1 – 4 & 14
A = ~2449 – 2475MHz, avoids 11b channels 1 – 6 & 14
B = ~2459 – 2485MHz, avoids 11b channels 1 – 7
ph[?|00-fe]
(base only)
Set Hop Duration
90H
 = default (=10ms)
pk[?|00-d0]
Set Minimum Data Length
01
 = default
pl?
(remote only)
Get Maximum Data Length (read only)
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 only)
pt[?|00-ff]
Set Data Transmit Delay
00H
 = default
pv[?|0|1]
(base only)
Set Slot Assignment Mode
= 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.
Set Alternative Frequency Band
When set to 1, limits the operating RF channel set to the 2448 to 2473MHz frequency
band for compliance with French regulatory standards.  When set to 2, sets appropriate
