Value Definition
3
Auto fallback high (11, 5.5, 2, 1)
4
Fixed medium rate (5.5)
5
Fixed high rate (11)
6
Auto fallback standard (2, 1)
7
Auto fallback medium (5.5, 2, 1)
Important:
For Multicast mode, use transmit rates of 1 or 2 Mbps for best results.
RTS Threshold
60 to 2347
RTS/CTS handshake threshold byte count. Less than 60 will interfere with control
packets.
WEP Key Rollover
Yes or No
WEP (Wireless Encryption Protocol) is an encryption method that allows devices
on a wireless network to transmit data securely.
This parameter interacts with the WATTCP parameter "Enable Encryption", and
the values for WEP Keys 1 through 4. When the WEP Key Rollover parameter is
enabled, the module will randomly change the WEP key.
2.5.2 [Radio SNTP Client]
The [Radio SNTP Client] section specifies the parameters for the Simple Network
Time Protocol (SNTP) client provided with the protocol driver. This client is
required in order to keep the driver's internal clock set correctly. This version of
the driver supports the unicast implementation of the SNTP Revision 3 and
stratum between 1 and 14.
The module can be configured to periodically synchronize its clock with a remote
SNTP server. Approximately every 6 minutes the module sends 10 consecutive
requests to the remote SNTP client (at approximately 6 second intervals). You
can check these requests and responses by looking at the SNTP Client
Configuration Menu (press the N key at the Configuration/Debug Main Menu). If
the module receives a valid response from the SNTP server, the computations
value will be also be incremented. After 10 consecutive successful requests and
responses, the module will synchronize its internal clock (an average is
performed based on all 10 responses for better accuracy). The Time Set Cnt
value is incremented every time the clock is synchronized.
After the synchronization is performed, the time valid register is set to Yes. If the
module cannot connect to the remote SNTP server after 3 consecutive attempts,
the time valid register is set to No. You can also configure the GMT settings to
use, and the database address where the date and time information can be
copied.
