Alpha indoor sign modem setup
Overview
Transmitting modem setup for Alpha signs
1. Set the DIP switches on the back of the transmitting modem as shown in Figure 1 on page 2.
2. Attach the transmitting modem to a computer that has AlphaNET version 3 or greater software installed
(see Figure 2 on page 2).
3. Start AlphaNET Diagnostics software.
4. When the Diagnostics screen appears, click Modem. Then make the selections as shown in Figure 3 on
page 3.
5. Click Configure Modem. One of the following two messages will appear:
• Modem Configured Properly — The transmitting modem is ready for use. It can now be connected to a
phone line. If the receiving modem has been set up and connected to a phone line, go to “Modem test”
on page 7. Otherwise, go to “Receiving modem setup for Alpha indoor signs” on page 6.
• Modem Failed To Configure — Make sure that the modem is on and is connected to the correct COM
port on the computer. Repeat step 4, but this time watch the RD and SD lights on the modem. These
lights should flash when you click Configure Modem. If the “Modem Configured Properly” message
still does not appear, contact Adaptive Technical Support (800-719-2838).
