RS-485 WIRELESS BRIDGE USER’S MANAUL REV. 02 12
Fig. 9 Terminal Session Command Example
Configuring Two-wire or Four-Wire Mode
The default setting for the RS-485 Wireless Bridge is two-wire mode. The communications mode is
controlled by the uart.mode command. To change to four-wire mode set the uart.mode to 3.
RS485> set uart.mode 3
Use the store command to write any changed parameters to non-volatile memory.
Changing the Baud Rate
The Wireless Bridge device is made up of two main components:
1. The host processor
2. XBee radio module
The host processor manages the USB interface, the information menu and communication to and from
the XBee radio module. Changing the device’s baud rate is a two-step process. In order to change the
baud rate successfully, the following steps must be followed in order.
1. Change the baud rate on the XBee module through the data COM port using AT commands or
the X-CTU program. Write the parameter to non-volatile memory.
2. Change the Wireless Bridge device baud rate through the information COM port using the set
uart.rate command. Write to non-volatile memory using the set store command.
