2 INSTALLATION MECHANICAL HF SSB TRANSMITTER T2130<br />

- When the power has been switched on at the RE2100, the RE2100 detects the existence of possible<br />

slaves.<br />

- When the T2130 has detected an error the T2130 has answered the previous message with the answer<br />

option (C). This results in a synchronized message from the RE2100.<br />

RECEIVER FREQUENCY<br />

Whenever the received frequency has been changed at the RE2100, the frequency is sent to the T2130.<br />

The T2130 ensures that a trans<strong>for</strong>mer is switched in at receiver frequencies below 4000 kHz and switched<br />

out at frequencies above 4000 kHz.<br />

KEY<br />

This command is sent continuously to the T2130 when the handset key is activated at the RE2100. The<br />

first time it is sent the command is followed by the actual transmitter frequency and the selected mode<br />

(telex etc.) at the RE2100. The answer is option (A). The following commands are sent without associated<br />

data. There are two different answers depending on the state of the T2130. In both states the T2130 has<br />

the full control of the step attenuator placed in the Exciter Unit (4) in the RE2100.<br />

- State one. Indicates that the T2130 and the AT2110 are NOT ready to transmit.<br />

The answers consist of the answer option (B) associated with an absolute step.<br />

The duration of this state is given by the duration of the automatic power setting and the tuning of the<br />

AT2110.<br />

- State two. The T2130 and the AT2110 are ready to transmit.<br />

The answers consist of the answer option (A) associated with an absolute step.<br />

This state continues until the key is released and the ‘Stop’ command is sent from the RE2100.<br />

TUNE<br />

This command is a subset of the ‘Key’ command. Only state one is per<strong>for</strong>med followed by the ‘Stop’<br />

command. The command is only sent from the RE2100 when the ‘TX’ and ‘Tune’ keys are activated.<br />

DUMMY LOAD KEY<br />

This command is equal to the ‘Key’ command except <strong>for</strong> the RF output power.<br />

The RF output power is delivered to the AT2110 built-in dummy load instead of the connected aerial.<br />

DUMMY LOAD TUNE<br />

This command is equal to the ‘Tune’ command except <strong>for</strong> the RF output power.<br />

The RF output power is delivered to the AT2110 built-in dummy load instead of the connected aerial.<br />

STOP TUNE/KEY<br />

This command always terminates the above mentioned 4 variants of the ‘Tune’ and ‘Key’ commands. The<br />

answer is option (A). The command is sent from the RE2100 at one of the following events:<br />
