– Configuration of a Mesh network site with a spare demodulator
The E7 interface configuration of the M7s at each remote site must be configured properly for the
network type and the size of the network.
The menu setting for the E7 interface in the M7 modulator and demodulator #1 would be:

<Intf: Send WAN Mode = >

<Intf: I/O Port 1 Mode = Data I/O>

<Intf: I/O Port 4 Mode = Dmd Input I/O>

<Intf: Rcv WAN Mode = >
The menu setting for the E7 interface in the M7 multi-demod #2 and #3 would be:

<Intf: Rcv WAN Mode = >

<Intf: I/O Port 4 Mode = Dmd Output I/O>
The physical connections shown in Figure 3 34 are specific to this example and are dependent on the
number of sites in the network. This example is a very simple Mesh network example and a more
complex network with more remote sites would require additional M7 hardware at each site and
careful attention to the E7 interface configuration on each M7.
