##### To set the ExecB controller's custom IP address If your system's IP addresses are assigned by the network administrator, you can connect a laptop to a controller's Local Access Port and then use either of the following methods to set the controller's custom IP address so that the WebCTRL® server can communicate with it. Set the custom IP address in SiteBuilder Set the custom IP address using PuTTY

- ###### To set a controller's custom IP address in SiteBuilder PREREQUISITES A computer with a USB port A USB Link Kit. See the USB Link Kit Technical Instructions. NOTE The USB Link Kit driver is installed with a WebCTRL® v5 or later system. But if needed, you can get the latest driver from http://www.silabs.com/products/mcu/Pages/USBtoUARTBridgeVCPDrivers.aspx. Install the driver before you connect the USB Link Kit to your computer. The appropriate controller driver
  Local Access port | Product | ExecB driver requirement
  5-pin | LGR or ME line | v1.73a.038 or later
  Round 8-pin | LGE, LGRM-E | v2.00 or later
4. CAUTION If multiple controllers share power but polarity was not maintained when they were wired, the difference between the controller's ground and the computer's AC power ground could damage the USB Link Kit and the controller. If you are not sure of the wiring polarity, use a USB isolator between the computer and the USB Link Kit. Purchase a USB isolator online from a third-party manufacturer. Connect the computer to the controller using the appropriate USB Link Kit cable(s). NOTE If using a USB isolator, plug the isolator into your computer's USB port, and then plug the USB Link Kit cable into the isolator. LGR line or ME line controller only: Turn off the controller's power, set its Enhanced Access Port DIP switch to ON, then turn its power on again. Set the controller's IP Address DIP switch to Assigned. In SiteBuilder, set your Configure > Preferences > Connections tab settings.
   Field | Value
   Port | The laptop's Com port number that the USB Link Kit is connected to.
   Baud Rate | For LGR, ME line | 115200
   For LGE or LGRM-E | 38400
   Data Bits | 8
   Parity | None
   Stop Bits | 1
Click OK. Double-click the controller. On the Address tab, select Specify a custom or DHCP IP Address. Type the IP Address, Subnet Mask, and Default Gateway Address. Click Download Address. After the download is complete, click Module Status to verify the router's address. LGR line or ME line controller only: When finished, turn off the controller's power, set its Enhanced Access Port DIP switch to Off, then turn the power on again.

7. CAUTION If multiple controllers share power but polarity was not maintained when they were wired, the difference between the controller's ground and the computer's AC power ground could damage the USB Link Kit and the controller. If you are not sure of the wiring polarity, use a USB isolator between the computer and the USB Link Kit. Purchase a USB isolator online from a third-party manufacturer. Download and install PuTTY from the PuTTY website. Connect the computer to the controller using the appropriate USB Link Kit cable(s). NOTE If using a USB isolator, plug the isolator into your computer's USB port, and then plug the USB Link Kit cable into the isolator. LGR line or ME line controller only: Turn off the controller's power, set its Enhanced Access Port DIP switch to ON, then turn its power on again. Set the controller's IP Address DIP switch to Assigned. Start PuTTY. Under Category > Connection, select Serial. Under Options controlling local serial lines, enter the following settings:
   Field | Value
   Serial line to connect to | Replace X with the computer's port number that the USB Link Kit cable is connected to. NOTE To find the port number, select Start > Control Panel > System > Device Manager > Ports (Com & LPT). The COM port number is beside Silicon Labs CP210x USB to UART Bridge.
   Speed (baud) | Type the appropriate baud rate from the table below.
   For... | Speed
   LGR, ME | 115200 for Rnet 38400 for S2
   LGE, LGRM-E, WebPRTL | 38400
   Data Bits | 8
   Stop Bits | 1
   Parity | None
   Flow Control | None
Click Open. A window similar to the one below appears. Type the number of the address field, then press Enter. Type the new address, then press Enter. Type`1`, then press Enter to restart the controller. Close PuTTY. LGR line or ME line controller only: When finished, turn off the controller's power, set its Enhanced Access Port DIP switch to Off, then turn the power on again.
4. ###### To remotely change a controller's custom IP address Steps 1 through 5 below change the IP address in the controller. Steps 6 through 10 change it in the system database. Communication with the controller will be disrupted until all steps are performed. On the WebCTRL® Network tree, go to the controller's Driver > BACnet Router Properties page. Under IP Configuration, select Enable IP configuration changeover. NOTE The field Allow remote management of IP configuration is for future use. In the Next column, type the new IP Address, Subnet Mask, and Default Gateway Address. Type the UDP Port that your server is using to communicate to all controllers. NOTE You must enter values in all 4 fields, even if the values will not change. Do one of the following.
   Set the Changeover timeout field to... | To have the controller use the Next settings...
   --- | ---
   0:00 | As soon as the controller can communicate with the Next Default Gateway Address.
   A specific length of time | As soon as the controller can communicate with the Next Default Gateway Address, or when the timeout expires, whichever occurs first.
Click Accept. On the System Configuration tree, select Connections. On the Configure tab, select the BACnet/IP Connection, then click Stop. On the Network tree, go to the controller's Properties page. Make the necessary changes in the Address, Subnet mask, and Default Gateway fields. Click Accept. On the System Configuration tree, select Connections. On the Configure tab, select the BACnet/IP Connection, then click Start. On the Network tree, go to the controller's Properties page, then click Module Status to verify communication with the controller.
