Configuring the HTTP Interface
To change the parameters in the HTTP Interface, select the Configure button at the bottom of the
HTTP Interface home page. Figure 6 shows the Configuration page in the HTTP Interface.
To Configuring the HTTP Interface:
1. Connect to the BACnet Communication Module via the Ethernet port for configuration.
2. Browse to the HTTP Interface page Figure 6
3. Select the Configure button. The HTTP Configuration page opens (see Figure 9.)
4. Enter the password. Default password is 1234.
5. Adjust the parameters for particular network.
Note: The factory default setting for the BACnet Communication Module’s MS/TP data
transmission rate is 38400 bps. If this is the data transmission rate you want for your
network, skip step 6.
6. To install the BACnet Communication Module on an MS/TP network, set the Data Transmission
Rate switch to the data transmission rate of your network. (see Changing the MS/TP Data
Transmission Rate section.) Select the Change or Reboot button to set the changes into the
BACnet Communication Module. You only need to reboot for the parameters that indicate a
reboot is necessary.
7. Select the Home button to return to the HTTP Interface page.
8. Verify that the changes were made. If the changes were not made, verify that the LAN Settings
are not selected in Internet Explorer.
9. Close your browser.
10. Remove the connection to Ethernet port you made in Step 1.
Changing the MS/TP Data Transmission Rate
The MS/TP Data Transmission Rate is changed with a switch inside BACnet Communication
Module. The switch has two positions: one for 9600 bps and 19200 bps and one for 38400 bps. The
switch is shipped from the factory in the 38400 bps position. You do not have to change this switch
if your network uses 38400 bps. In addition to setting this switch, you must also set the transmission
rate on the HTTP interface. After you set the data transmission rate, verify that you have removed the
Ethernet cable from the BACnet Communication Module so that MS/TP communications can proceed
efficiently.
