5: Configuration via Serial Mode or Telnet Port
Fixed or Automatic Data Rate
MatchPort permits the control of the transmission rate. Select
0
to set a fixed data
rate or select
1
to set an automatic data rate. The default is
1
(auto fallback).
TX Data rate: 0=fixed, 1=auto fallback (1) ?
Transmission Data Rate
If the above
TX Data rate
is set to
fixed
, the selected data rate is the MatchPort’s
fixed transmission rate. If the above
TX Data rate
is set to
auto fallback
, the
selected data rate is the MatchPort’s maximum data rate. Lower data rates allow for
larger distances. It may also be required when communicating with older devices.
The default is
54
Mbps
.
TX Data rate 0=1, 1=2, 2=5.5, 3=11
4=18, 5=24, 6=36, 7=54 Mbps (0) ? _
Minimum TX Data Rate
Selects the minimum data rate the device will use when auto-fallback is enabled. The
default is
1 Mbps
.
Minimum TX Data Rate 0=1, 1=2, 2=5.5, 3=11, 4=18, 5=24, 6=36,
7=54 Mbps <0> ? _
Note:
If Auto Rate Fallback is enabled and a minimum TX data rate other than
1Mbps is configured, the radio will operate in Single Rate Drop mode. This means
that if a rate drop becomes necessary, the radio will drop from the maximum rate to
the lowest rate, ignoring all rates in between. This reduces the potential number of
packet retransmission attempts, because the radio attempts to transmit a packet
three times before transitioning to the next lowest TX rate.
Note:
If the Minimum TX Data Rate is set for 54 Mbps for the minimum and
maximum, the auto fallback capability is eliminated.
Max TX Failures
Determines the maximum number of consecutive transmit packet failures before the
device will drop its association with the AP and attempt to establish a new one. The
range of attempts is 6 to 64; 255 equals disabled. The default is
6
failed attempts.
Max failed packets <6 – 64; 255=disable>: <6> ? _

This allows the software to turn off the radio when expecting not to receive or
transmit soon. This feature reduces the power consumption by up to 140 mA.
