24. Your configuration of the AP is complete. Return to the Starting Information screen
(Step 1 above) and repeat all steps with the remote unit. All of the settings/values are the
same.
MDLC over IP Port
iNET radios can be configured to work with the MDLC over IP port on ACE3600 RTUs (see
Configurations 4-7 above.)
MDLC over IP supports:

IP Gateway 4.xx configured with MDLC over IP over Ethernet port.

ACE3600 RTU Ethernet port

ACE3600 RTU RS232 port configured as MDLC over IP over PPP connected to
Standard modem.
When using an RTU with EP Ethernet port, connect the RTU Ethernet port to the iNET
Ethernet port. The IP Port should be on the same subnet as the iNET. Its Subnet mask and IP
Gateway should be the same. The rest of the configuration should be the same as an MDLC
over IP port (i.e. configuring the port and setting the appropriate baud rate and Link ID, and
downloading the IP Conversion Table.) The P Conversion Table is needed to communicate
with other RTUs connected over PPP or Ethernet.
The rest of the configuration should be the same as an MDLC over IP port (as above). All IP
settings are obtained dynamically from the modem when connecting to it. The RTU PPP port
should be connected to COM2 on the iNET radio using a computer adapter. The following
describes how to configure iNET COM2 modem for PPP.
After configuring the IP Gateway, EPIB for Ethernet, and RTU (for PPP) with MDLC over IP
port, they can all communicate on the iNET network as if they all reside on a LAN. All routing
between them is done via the iNET network, and if a LAN is involved, using other routers as
well. Any RTU can communicate with any other RTU or IP Gateway. A single Link ID should
be set for all RTUs/ IP Gateways on these ports.
Note however, that if the MDS radio was connected via External Modem port (serial), or via a
Terminal Server (e.g. Equinox) over serial port, it is a completely different MDLC
link/protocol. A different Link ID should be set in the RTU/IP Gateway when using this
configuration. If both coexist on the same iNET network, each should have its own Link ID
with MDLC network configuration downloaded to all units.
Use the iNET radio programming software to program the AP (Access Point) and then the
remote with the following settings.
Note:

Radio firmware should be 4.4.0 or above.

IP Address refers to the Ethernet port IP and not the “over the air” IP.
The following shows Access point configuration for MDLC over IP but it is exactly the same
for Remote.
