Logon to the equipment

Point to Equipment / Connect to open the Connect dialog box.
Select Logon, accepting the default value of 0 for the Equipment ID.
Select Local. If parameters have to be downloaded to the equipment,
uncheck Read access only. If a password has been downloaded into
the equipment previously and if Read/write access is desired, enter the
correct Write password. If immediately after logon, configuration
and/or status data are to be uploaded, check the boxes Upload
configuration and/or Upload status. Finally, click OK.

Communication media

4.4.3.1.1.

Modems

The phone modems should be capable of transmitting at least 9'600
bps. Modems compatible to ITU-T V.32 or higher fulfil this
requirement. The highest data rates are obtained with ITU-T V.90 (or
higher) modems. Also make sure that the modems data format can be
set to 8 data bits, even parity bit, one stop bit.
4.4.3.1.2.

Cables

For the connection between modem and ETL600, a 9 pin null modem
cable has to be used:

• Communication inactive (Off line mode)
• HMI600 waits for an answer from the equipment. By
clicking the red circle, the communication is interrupted.

When an unsupported COM port has been selected in the
previous step (refer to section 4.4.2.2), an error message
will pop up: "Could not open COM port".
