WLM

The Retry Odds parameter determines the probability that the remote will attempt to retransmit the packet to the
master; a low setting will assign low odds to the remote attempting to transmit and conversely a high setting will
assign high odds. An example of how this parameter might be used would be when considering two different remotes
in a multi-point network, one close in with a strong RF link and the other far from the master with a weak link. It may
be desirable to assign a higher Retry Odd to the remote with the weaker link to give it a better chance of competing
with the closer remote for the master’s attention.

Another parameter in a multi-point network is 

(4) DTR Connect

. This setting is not applicable in the WLM’s and

should not be changed from a factory default of 0.

The repeater’s hopping pattern must also be set in a multi-point network; this is accomplished with parameter 

(5)

Repeater Frequency. 

Setting this parameter is in contrast with point-to-point mode where the repeater

automatically uses the master’s hopping pattern. The repeater may be programmed to either use the master’s
hopping pattern selection (0) or its own selection (1).

Option 

(6) NetWork ID

 allows multi-point networks to be established without the use of the Call Book. If the

NetWork ID is set to any value lower than the default (255) the remotes in the multi-point network will communicate
with the first multi-point master or repeater heard with the same NetWork ID. When the NetWork ID is used multi-
point masters and repeaters may be replaced without reprogramming all of the remotes in the network. In addition,
this allows a remote to establish communications with different masters (though not at the same time) without
having the call book numbers in the Call Book. This is very useful in mobile multi-point applications. 

(8) Multi Master

Synch

 is reserved for multi-point applications with concentrations of master units where it is necessary to reduce

interference between the masters. Please contact the factory for more information on the use of this feature.

(9) 1PPS Enable/Delay

This setting is not applicable to the WLM and should not be changed from the factory default of 255.

(A) Remote/Repeater

The Remote/Repeater mode allows a WLM in a multi-point system to simultaneously act as a remote and a
repeater. When in this mode a WLM will repeat any packets sent from a master as well as send them out the
Ethernet port. This gives a WLM set as a repeater to act as a remote at the same time. 0 disables this mode, 1
enables it. For this feature to work, the modem must be configured as a point-to-multipoint repeater.

(B) Diagnostics

The WLM has the ability to run a diagnostic program while in normal operations. Contact the factory for
additional information.

(C)

 

SubNet ID

The default setting is “Disabled.” Please see the SubNet ID section of this manual.

(D) Radio ID

Used with the Diagnostics. Contact the factory for additional information.
