I. Modbus TCP/IP - Setup Procedures for dap4 Ethernet Card
Note: When connecting to the Ethernet card, a crossover cable must be used
1. Configure BMS PORT 1 into “BACnet TCP IP” protocol in menu G: Network Config of the
dap4 controller.
2. All Ethernet cards were set up for a DHCP server. You must give the card its factory IP
address to access the card and then switch it to the Ethernet protocol.
3. To do a factory reboot of the card, shut of power to the dap4 controller. Next, press and hold
the button on the card. Now, power on the dap4 controller. Wait approximately 20 seconds
until the status LED begins to blink red 3 times slowly. After the first Red blink, release the
push button. After releasing the button, wait approximately 50 seconds and the card is now
able to be communicated to.
4. The default settings for the card are as follows.
IP address – 172.16.0.1 Net Mask – 255.255.0.0 Device Inst - 77000
5. Once you have reset the Ethernet card, you must now configure your network card in your
PC to 172.16.0.*
* any value other then 1.
6. After your PC’s network card is configured, open Internet Explorer and enter the card’s IP
address (172.16.0.1.)
7. The following prompt will be displayed on your PC’s Screen (user name – admin, password –
fadmin)


8. After entering the correct information to log on to the Ethernet card, you will be taken to the
following screen.
9. Click the configuration tab on the left. Then click on the BACnet tab across the top of the screen.
10. This field is where you can change the settings for the card. The device instance of the card is
changed beside the pCOWeb Device Inst text. Each card must have its own unique device
instance.

11. The variable ranges can be set on the same page. Scroll to the bottom to change these ranges.
12. After you have set up your card, click Submit.
13. After your changes have been accepted, you may now change you IP address (if applicable.)
While still under the configuration tab, click network across the top of the screen.
14.
15. Under Eth0, change the IP address and Netmask to your desired values.
16. Scroll to the bottom of the screen and click submit.
17. It will take approximately 5 minutes for the IP address change to take
18. If there is no communication between the card and the BMS network, the Push Button can be
used to recall the factory setting configuration of the card: With the controller powered OFF,
turn the power ON while pressing and holding the push button. The status LED will blink red
and green rapidly for about 3 seconds, after that, it will stay as green. Wait for about 15
seconds, the LED will turn red. At this point, release the Push Button immediately. Lastly,
wait another 30 seconds for the controller to start up and establish the connection. When
started in this mode, the BMS card is reset to original factory setting temporarily; it will revert
to custom configuration (if any) after a reboot.
