Advanced Setup

Modbus Communication Parameters

Setting up the Network and Device IDs, powering up the devices, and conducting the Site Survey for a host-connected network is the same as
for the standard DX80 wireless system. All device I/O for the network is accessed using the host/master device.
To access the Modbus device, you may first need to configure system-level communication parameters on the DX80 Gateway, in addition to the
serial hookups shown below. The following procedure is necessary to change the Gateway Slave ID, Baud Rate, and Parity.

Parameter

Default Value

Description

Slave ID

1

Defines the slave number (01-99) for the serial Modbus RTU protocol. When operating more than one
network with a Modbus Master device, change the Slave IDs.

Baud Rate

19200

Defines communication data rate (19.2, 38.4 or 9.6 kbps) between the Gateway and the Host through the
serial interface.

Parity

None

Defines serial parity (none, even, or odd) between Gateway and Host.

Setting the Slave ID, Baud Rate, and Parity

Similar to Network ID, the Slave ID, Baud Rate, and Parity parameters can be changed in the Device Configuration (*DVCFG) system menu
option. Follow the top level system menu through *DVCFG to the Slave ID (SLID) parameter. The LCD displays an alternating current value and
new value for the parameter.
On the Gateway or GatewayPro, single-click button 1 to move across the top level menu options to the *DVCFG (Device Configuration) menu

Setting the Slave ID

1. Press button 2 once to enter the Device Configuration (DVCFG) menu.
2. Press button 1 to move to advance through the items in the DVCFG menu. Stop advancing when you’ve reached the setting to the

slave ID (SLID).

3. Press button 2 once.

The screen displays the current slave ID number.

4. Press button 1 to advance across the three digit slave ID while using the right rotary dial to select the number. To make a change,

rotate the right rotary dial to zero, then to the desired number.
As you press button 1 to select the digit, the digit changes to reflect the position of the right rotary dial. To set the slave ID to 3, the
display should read 003.

5. Press button 2 once to save the new slave ID.

The display reads SAVED.

Setting the Baud Rate

Continuing from the previous menu position, follow these steps to set the baud rate.

1. Press button 1 once to move to the next menu option, the BAUD rate.
2. Press button 2 once to enter the BAUD rate submenu and display the current setting. Single-click Gateway push button 1 to cycle

through the available options. Stop on the desired setting.
The options are 9600, 19200, 38400. The factory default is 19200.

3. Press button 2 once to save the new setting.
