Wiring Instructions
1. Connect 2 wires to the two connections listed under "2-Wire" on the back of the VTO2000A-2
2. Connect 2 wires to the two connections listed under "2-Wire0" on the back of the VTH1550CHW-2
3. Connect the other end of the 2 wires from the VTO2000A-2 to the 2 connections listed under "CH1" on the VTNC3000A.
Connect the other end of the 2 wires from the VTH1550CHW-2 to the 2 connections listed under "CH2" on the VTNC3000A.
Connect a 24 VAC, 3 A power supply to the appropriate positive and negative connections on the VTNC3000A.
Connect a network cable to the "LAN" connection on the VTNC3000A.
VTO2000A-2 Setup Instructions
1. Connect your computer directly to the VTNC3000A, and set your computer's IP address to 192.168.1.x (x=any available IP), subnet mask 255.255.255.0. This will ensure you are using the same IP scheme as the VTO's factory defaults.
2. Launch Internet Explorer and enter the VTO's default IP address into the URL address bar: 192.168.1.110. If you cannot see the web page load on this default IP, then tap the tamper button located on the back side of the VTO 5 times, while the device is powered on, until you here a beep and the device reboots. Once at the login page please enter the default username (admin) and password (admin).
3. After the login page please select Network Config on the left side. Under the TCP/IP tab please input the desired network configuration. For this exercise, the network uses a 192.168.2.x scheme, and on a static IP address on the LAN (DCHP-Off). After the settings have been entered, select OK. Changing network schemes will disconnect the device when directly connected. From here the VTNC3000A can now be plugged into the network, and accessed from the network.
VTH1550CHW-2 Setup Instructions
1. Once the VTH has booted up please tap the screen to wake up the main menu.
Press and hold Setting until a login menu appears on the screen.
Tap the area next to Password: and enter 888888 to get into the main settings of the device.
2. At the Network area of the VTH tap Wired IP.
3. Here you can set a static LAN IP, then select OK.
Alternatively you can use DHCP to grab an address from your Routers DHCP server, then select OK.
4. To setup the Room No. tap the field and enter a four digit room number (or the number that had been added on the VTO) then select OK.
5. Tap VTO Set on the left and enter the VTO IP Address, username, and password that you configured in the VTO setup process.
Then Enable Status to ON.
Note:If the VTO not Connected symbol in the upper right corner does not go away, then you will need to reboot the device through Setting -> Reboot. If this does not work repeat this step. If that does not work, reboot the VTO and repeat this step.
6. Once the VTO not Connected status is cleared, attempt to make a call from the VTO by pressing the silver door bell button.
