To connect your control equipment to Pearl-2, you need a standard RS-232 cable.
To connect the serial port cable:

are:
l Baud rate set at 19200
l Parity set to none
l Stop bits set to one
To configure serial port flow control:
1. Login to the Admin panel as admin, see Connect to the Admin panel.
2. From the Configuration menu, click Serial Port . The serial port configuration page opens.
3. Select Hardware, Software, or None from the drop-down menu.
