Configuring the outputs to operate with Transmitter Encoders

The principle of operation is as previously described in the operation of the RF600D.

Note that the on board RF600D will only operate the digital outputs of ‘pre-learnt’ transmitter

encoders. Upto 48 unique transmitters may be learnt. The Serial output will be valid whenever a

transmitter encoder is operated within range of the RF / IR receiver as long as the transmitter

encoder has a matching Manufacturers Key.

(For a unique manufacturers key please contact our

sales Department) No ‘pre-learning’ of the transmitter encoder is required for the serial data output.

Therefore if a serial output is required from a pre-learnt transmitter encoder the digital and serial

outputs must be logically gated together (using a simple logic gate).

Using HyperTerminal to view the Serial Data

The data can be viewed using any PC running Windows HyperTerminal using the following configuration.

(Assume Com 1 is the port being used:)

To start HyperTerminal go to :-

Start > Programs > Accessories > Communications > HyperTerminal.

Select Hypertrm.exe

Enter a name and select an Icon.

The ‘Connect To’ dialog box should now be open.

Select “Direct to COM1” in the ‘Connect Using’ Field and select OK.

In the COM1 Properties Dialog Box set the fields with the following parameters:

Bits per Second:

9600

Data Bits:

8

Parity:

None

Stop bits:

1

Flow control:

None
