ISM Radio
8.4.1 ISM Radio
The internal ISM radio of the DXM Controller is set at the factory to be Modbus device address 1 (Modbus ID 1).
For some applications, you may need to change this ID. The best way to adjust the Modbus device address is by using the
LCD menu system of the DXM Controller. Any other method may cause issues with the DXM Controller not knowing which
Modbus device address is assigned to the radio, which causes issues with running Binding or Site Survey from the LCD
menu.
To setting the Modbus ID on the internal radio, select the System > ISM Radio menu. There are two options: Modbus
ID and Advanced Options.
Modbus ID—Set the ISM Modbus ID to any number (1 through 247) not being used by the DXM system. Processor Local
Registers allocate ID 199, the I/O board is set to ID 200, and the display board is set to ID 201. With a DX80 Star
Gateway device, it's easy to choose a new ID. With a MultiHop network, remember that the master MultiHop radio
allocates a range of Modbus IDs for wireless devices, typically 11 through 110.
When setting the new ISM Modbus ID, the system changes the Modbus ID on the internal radio and changes the reference
to it on the DXM Controller. The reference Modbus ID is what the DXM Controller uses to access the internal radio when
running Binding or Site Survey.
Advanced Options— The Advanced Options menu is typically not used unless the Modbus ID is changed without the DXM
Controller being involved, such as when you write directly to the radio Modbus registers.
If the internal Modbus ID of the radio was changed, but not recorded, use Auto Detect Radio to determine the radio ID.
The auto detect routine broadcasts discovery messages and waits for a response. If devices are connected to the external
RS-485 ports, they may need to be disconnected for this process to work properly.
Reference Type selects the radio type between DX80 Star architecture radios and a MultiHop radio. The DXM Controller
uses this reference to determine how to communicate to the internal radio. If set incorrectly, the DXM Controller may not
be able to run Site Survey from the LCD menu. Unless you are changing or adding the internal radio device there should
no reason to change the radio type.
The Reference Modbus ID defines the Modbus ID the DXM Controller uses when communicating with the internal radio.
If this is set incorrectly the DXM Controller will not be able to run Binding or Site Survey through the LCD menu.
8.4.2 Ethernet
Use the System > Ethernet menu to set the IP Address, Gateway Address, and Subnet mask of the DXM Controller's
Ethernet interface. You may change these settings either from the LCD menu (System > Ethernet) or from the XML
configuration file created by the DXM Configuration Tool.
The network address settings from the LCD menu have the highest priority and override settings in the XML configuration
file. To use the parameter settings from the XML configuration file or use DHCP, execute the Reset under System >
Ethernet or use the LCD display to set the IP Address, Gateway Address, and Subnet Mask to 255.255.255.255. Reboot
the DXM Controller after changing the Ethernet parameters.
The Ethernet cable should be attached before powering up the DXM Controller.
8.4.3 Provision Cell
If the DXM Controller has a cellular modem installed, the modem must be provisioned on the network. This menu will
provision the cellular modem on the network. For step by step directions, see
on page 55.
