6.4.1 ISM Radio
DX80/MultiHop ID—The ISM radio is set at the factory to be Modbus device address 1 (Modbus ID 1). For some
applications, you may need to change the Modbus ID. Adjust the Modbus device address using the LCD menu system. Any
other method may cause issues with the DXM1200 not knowing which Modbus device address is assigned to the radio,
which causes issues with running Binding or Site Survey from the LCD menu.
Set the radio Modbus ID to a valid number (1 through 247) that is 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 Gateway (star
network), 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 DXM1200. The reference Modbus ID is what the DXM1200 uses to access the internal radio when running
Binding or Site Survey.
Auto Detect Radio—If the internal Modbus ID of the radio was changed or the internal radio was changed, but not recorded,
use Auto Detect Radio to determine the radio ID and radio type. The auto-detect routine broadcasts discovery messages
and waits for a response. If other devices are connected to the external RS-485 ports, they may need to be disconnected
for this process to work properly.
Advanced Options—The Advanced Options menu is typically not used unless the Modbus ID is changed without the
DXM1200 being involved, such as when you write directly to the radio Modbus registers.
•
Reference Type selects the radio type between DX80 star architecture radios and a MultiHop radio. The DXM1200
uses this reference to determine how to communicate to the internal radio. If set incorrectly, the DXM1200 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.
•
Reference Modbus ID defines the Modbus ID the DXM1200 uses when communicating with the internal radio. If this
is set incorrectly, the DXM1200 will not be able to run Binding or Site Survey through the LCD menu.
Max Node Count—Defines the maximum number of devices for the DX80 wireless network.
Binding #—This parameter allows the user to define the Binding code within the ISM radio. Typically, you will not have to
adjust this number unless you are replacing an existing Gateway or master radio.
RF Ctrl—Displays the status of the ISM radio DIP switch 1 (off or on). The menu doesn't allow the user to change the DIP
switch setting through the display.
6.4.2 Ethernet
Use the Ethernet submenu to sets the IP Address, Gateway Address, and Subnet mask of the DXM1200's Ethernet
interface. You may change these settings either from the LCD menu (System Config > Ethernet) or from the XML
configuration file created by the DXM Configuration Software.
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 Config >
Ethernet or use the LCD display to set the IP Address, Gateway Address, and Subnet Mask to 255.255.255.255. Reboot the
DXM1200 after changing the Ethernet parameters.
The Ethernet cable should be attached before powering up the DXM1200.
6.4.3 LCD Contrast
Use the LCD Contrast option to adjust the LCD contrast. Adjust the starting number lower to decrease the display contrast.
The factory default is 28. Do not set a number less than 15 or the display may not be bright enough to see to change back.
6.4.4 Reset
Use the Restart menu to force the main processor to restart. This does not affect the other boards in the system.
