5.3.2 Connect-Login-Mode

If the code for the protection against unauthorized access to the data terminals is activated,

the device is in this mode after a successful connection set up via a call. In this case the

device retransmits the signals to the calling control station

as command for entering the code.

There are 3 options to change the mode:

1. Change-over to the Connect-Transparent-Mode

If now the 8-digit code (ComuCont – ID) with closedown <CR> is transferred to the

device, this results into a change-over into the Connect-Transparent-Mode.

2. Change-over into the Connect-Parameterization-Mode

Instead of the code, you can change-over into the Connect-Parameterization-Mode via

the signal sequence $$$ (see Disconnect-Transparent-Mode). When closing down this

Mode, the device returns into the Connect-Login-Mode.

3. Starting of call-notes

When the device receives the call-note command, it hangs up automaticallly and after a

short stop starts the required recall.

Call-note command: !Sncccccccc<CR>

n: Telephon number register 0-3 of the ComuCont Dual

cccccccc: Recall recognition in case of a call to the control station

Example:

ComuCont Dual transfers: Login:

Control station transfers: !S1abcdefgh<CR>

ComuCont Dual transfers: OK <CR><LF>

(in case of a default there will be no response)

After the OK, the device hangs up and starts the recall to the telephon number from

At a recall, the device is in the Connect-Transparent-Mode.

5.3.3 Connect-Transparent-Mode

This mode is reached,

- via a telephone connection by a recall (Call-note or recall automatic)

- via a telephone connection by a call, if the Transparent-Mode is not protected by a code

- via the Connect-Login-Mode.

In this mode, the control station can directly communicate with the terminal. Via the

sequence „$$$“ (see Disconnect-Transparent-Mode) one can change-over into the

Connect-Parameterization-Mode. However, this is only recommended with a 8.1,None

connection.

5.3.4 Connect-Parameterization-Mode / Disconnect-Parameterization-Mode

Regularly this mode is reached via the signal sequence „$$$“ (see Disconnect-Transparent-

Mode). In this mode, the following indicated commands can be transferred to the

ComuCont Dual. In case of remote parameterization, however, writing as well as reading

of the ComuCont-ID is disabled when the parameterization-code is activated. Disabling

can be opened via the command L.

Exit the mode via the command Q (see parameterization).
