Main Menu Option (0): Set Operation Mode
When item (0) is selected, the Operation Mode Menu appears as shown in figure 12. The Operation Mode option is used to
designate the method in which the particular DDAA1000/SRM will be used. The DDAA1000/SRM operates in a master to
remote configuration; therefore, any radio modems that are intended to operate together must be set up as such. In a point-
to-point setup, either the master or remote may be used on either end of the communications link. One consideration when
setting up the radio modems is that a number of parameters are controlled by the settings in the master; therefore, you may
wish to deploy the master on the communications end where you will have easier access to the radio modem.
Figure 12: Mode Menu
Shown below are example settings. Please refer to supplied configuration sheets for your modem’s configuration.
(0) Point-to-point Master
The DDAA1000/SRM operates in a master/remote configuration. When designated as a master in point-to-point
mode, the radio modem will call any or all remotes it is instructed to call in the call book. The master determines
the settings used for all Radio Transmission Characteristics, regardless of the settings in the remotes and/or repeaters.
(1) Point-to-Point Remote
When set up as a point-to-point remote, a DDAA1000/SRM will communicate with any master in its call book,
either directly or through one or two repeaters. When functioning as a remote, the Entry to Call feature in the
radio modem’s call book (Figure 13) is not operational. The remote will communicate with any master on the list that
calls.
(2) Point-to-Multi-Point Master
The DDAA1000/SRM may be set to run in multi-point mode, which allows one master to simultaneously be in
communication with numerous remotes. A point-to-multi-point master will communicate only with other radio
modems designated as point-to-multi-point remotes or point-to-multi-point repeaters.
(3) Point-to-Multi-Point Remote
Setting (3) allows the radio modem to operate as a remote in a multi-point network.
Please refer to the section entitled multi-point Operation, for more information on running a multi-point network.
