When the system is in Pass-Throughmode [CC98], commands and responses are sent between the transmitter and receiver. If the system is not in Pass-Throughmode, all of the receiver responses to the transmitter’s button commands are buffered until you return the system to mode, at which time the buffered responses are sent back to the controlling device. In this way, the controller can track the activity that has occurred.

After you are finished programming the transmitter, always terminate the session by sending an address packet to another unit with a different address. This prevents the transmitter from responding to commands meant for another unit.

Transmitter responses

When a command is valid, the transmitter performs the command and sends the following response:

[R0•{address}•{echo of the command sent}•]

When a command is invalid, either because the command is not recognized or it contains invalid parameters, the transmitter sends the following response:

[R1•{address}•{echo of the command sent}•]

Using the command/response table

The command/response table begins on page 4-14. The command set is case sensitive and commands must be entered as shown. The table below shows the hexadecimal equivalent of each ASCII command.

ASCII to HEX Conversion Table

Space

Symbols, defined below, are used throughout the command/response table to represent variables in the command/response fields. Command and response examples are shown throughout the table.

Symbols

•= Space

X1

= Address number 00 – 97

00 addresses all units, but individual units do not respond.

97 is the factory-installed default for the transmitter.

Transmitter address + 1 is defined as the device connected to the receiver’s RS-232 port.

The very first command that you send to the transmitter must be the connect, [CC X1 ], command, where X1 is the transmitter’s address. The transmitter will not accept other commands or respond until it has been addressed.

The very last command that you send to the transmitter should be the connect, [CC X1 ], command, where X1 is a different address. This prevents the transmitter from accepting and responding to commands meant for other devices.
