Chapter 2 Software Overview 23

Terminal Emulator Screen

This screen acts as a simple terminal emulator to communicate directly with the controller. It has two main

uses:

1) You can view serial transmissions from the controller. This can be useful in several instances:

• When you apply power to the controller, you can make sure that it’s working by looking for

the serial transmissions from it. If you see nothing, something is not set up properly. If you

see only unrecognizable characters, the PC’s baud rate setting is probably incorrect.

• When testing your schedule, you can include commands for the controller to transmit serial

messages. You can view these messages with the terminal emulator and verify things are

happening as you expect.

2) You can send commands directly to the controller. You probably won’t need to use this capability,

as the other control screens can handle almost every command you’ll want. However, if you’re

writing your own program to control the controller, you can use this screen to test out the command

format and make sure you know exactly how it works.

Several points should be noted about this terminal emulator:

• To send commands to the controller, enter ASCII text in the top text box, then press the carriage

return. The entire string of text, including the carriage return, will be sent at one time when you

press the carriage return. You can use the backspace key or edit the text to get it right before you

send it. Refer to chapter 16, Serial Interface, for more details.

• The large window displays the data received from the controller. It does not show the data you send

to the controller.

• The normal command response from the controller includes some unprintable characters. These

are shown in the window as a square box.

You can also use any standard terminal emulator or communications program to communicate with the

controller if you wish.

IR Learn Screen

Use this screen to teach infrared signals to the controller. It can then transmit them to control your

audio/video equipment

IR Test Screen

With this screen, you can:

• Transmit any infrared signal that is currently loaded in the controller.

• Transmit any “standard” format IR signal. You can transmit a signal with any Device Code and Key

Code. You can use this to “train” a “learning” remote, which can then be used to control

HomeVision.

• When transmitting signals through a Multifunction Expansion Board, you can select which zone(s)

you want to transmit out of.

• Determine the Device Code and Key Code of any standard format IR signal that you transmit to the

controller. The screen displays this information for infrared signals that the controller receives.
