Frequency channel of the module can be set by
”/c [number]”
command, where value 0, 1, or 2 means number
of frequency channel to be tuned. Change of frequency channel is effective only after module reset. Example of
sequence of commands for module setting to the frequency channel ”1”:
sysmon>/c 1
sysmon>/W
sysmon>/x
The
”
SLRF Hop Count”
parameter is a maximum number of re-transmissions of the messages, broadcasted by
the module. If, as an example, the parameter is set to value ”3”, each message originated by the module will be
discarded after three re-transmissions (it is repeated no more than 3 times). This mechanism prevents the system
from uncontrolled circulation of the message within the network. It is recommended to set the parameter to ”n”
or n+1” value, where ”n” is the least number of re-transmissions which is necessary to get the massage to its
destination. If the
”
SLRF Hop Count” value is too low, the message is discarded before reaching of its destination.
If the
”
SLRF Hop Count” value is too high, capacity of the network is loaded by useless repeating of the messages.
The
”
SLRF Hop Count” parameter can be set by
”/h [number]”
command, where the value from 0 - 15 interval
means the maximum number of re-transmissions (”hops”) of the messages, broadcasted by the module. Example
of command for setting of
”
SLRF Hop Count” parameter to value of 3 ”hops”:
sysmon>/h 3
The
”
SLRF Repeater flags”
parameter is intended for setting of repeating (re-transmission) mode. Repeating
mode can be set by using of
”/f[+-] [flags]”
command, where the required mode is chosen by entering of one of
following pre-defined symbols (
”
flags”):
- value
” ”
(without flag) - none of below mentioned functions is involved
- value
”e”
- setting of basic repeating mode (without back transfer suppression)
- hodnota
”Z”
- setting of advanced repeating mode with back transfer suppression (AZRA)
- value
”m”
- designating of the module as a
”
Master” of virtual bus
Example of command for setting of the module as a repeater with
”
Advanced repeating mode AZRA” (recommended
setting):
sysmon>/f e Z
The
”
RF Driver flags”
parameter is intended for setting of module transceiver mode. The mode can be set by
using of
”/F[+-] [flags]”
command, where the required transceiver mode is chosen by entering of one or more of
following pre-defined symbols (
”
flags”):
- value
”C”
- full anti-collision protection (carrier and frame transmission detect) enabled
- value
”R”
- limited anti-collision protection (carrier detect) enabled
- hodnota
”W”
-
”
Wake On Radio” (WOR) function of the receiver enabled
- hodnota
”G”
-
”
High Gain” function enabled (it has no effect for WM868-MS-LP-H module)
Important notice:
The
”C”
and
”R”
functions are alternative options and their setting works as a
change-over switch
(when one
of them is enabled, second one is automatically switched off). The
”W”
and
”G”
functions are independent. Their
flags can be added or removed
individually
by using of +/- symbol before the flag.
Example of command for common setting of
”
Full anti-collision protection” and
”
Wake On Radio” functions and
corresponding record in the module configuration summary:
RF Driver flags:
R
sysmon>/F C +W
RF Driver flags:
CW
Example of command for switching of protection to
”
Limited anti-collision protection” mode and corresponding
record in the module configuration summary:
RF Driver flags:
CW
sysmon>/F R
RF Driver flags:
RW
