can select a channel for GW-DS300N. If enabling
this mode, the PSM mode will NOT take effect and
the Preamble function will be enabled.
TX Power Choose the TX (transmission) Power according to
the real environment. If you want to lower the
transmit power of the adapter for saving the
power of the system, you can select the lower
p e r c e n t a g e s f r o m t h e l i s t . T h e l o w e r p o w e r
will cause the lower signal strength and the
coverage range. The default setting is “Auto”.
Preamble The preamble defines the length of the CRC (cyclic
redundancy check) block when communicating
among the wireless networks. There are two types
of preamble: Auto and Long Preamble. Intensive
network traffic areas should use the short preamble
type.
RTS Threshold Here it defines the minimum packet size required for
RTS (Request to Send). Select a value within a range
of 0 to 2347 bytes. Normally, if there are no hiding
nodes problems, the values no need to be altered.
Fragment Threshold The value defines the maximum size of packets; any
packet size larger than the value will be fragmented.
If you have decreased this value and experience
higher packet error rates, you can increase the value
again, but it will likely decrease the overall network
performance. Select a value within the range of 256
to 2346 bytes. The default value is 2346.
