(4) Point-to-Point Remote/Repeater
Option 4 allows you to designate the radio modem to act as either a remote or a repeater, depending upon the
instructions received from the master for the specific communications session. When a radio modem is placed
in an ideal location, this setting offers the flexibility of using that radio modem as an end point in the
communications link (remote) or to extend the link to a further point (repeater). These functions are not, however,
available simultaneously (the radio modem cannot act as both a remote and a repeater at the same time).
Note:
Configured as a repeater, a radio modem has no security features as explained below. When a radio
modem is designated as a Point-to-Point Remote/Repeater, it will allow any master to use it as a repeater.
(5) Point-to-Point Repeater
WLM radio modems allow the use of up to two repeaters in a communications link, significantly extending the
operating range. When designated as a repeater, a radio modem behaves as a pass-through link. All settings for
the call book, baud rates, and radio transmission characteristics are disabled. A repeater will connect with any
master that calls it (the repeater must still be set up in the master’s call book).
The use of one repeater in a communications link will reduce the top data throughput available when compared
to a direct master to remote link (generally on the order of 50%). The throughput does not decrease further if two
repeaters are used.
(6) Point-to-Point Remote/Master Switchable
Mode 6 is not applicable to the WLM radio modems.
(7) Point-to-Multi-Point Repeater
Setting (7) allows the radio modem to operate as a repeater in a multi-point network.
Please refer to the section entitled, multi-point operation, for more information on running a multi-point network.
(F) Ethernet options
