Connect and configure the RS-232 port
To connect your control equipment to Pearl Mini, you need a standard RS-232 null-modem cable and a USB to
RS-232 serial adapter cable. Adapter cables are not included with Pearl Mini.
Only certain adapter chipsets are supported, Epiphan recommends this adapter cable from Startech.
To connect the serial port cable:
1. Attach the cable to the control interface.
2. Connect the USB to RS-232 serial adapter to the null-modem cable.
3. Connect the USB to RS-232 serial adapter to one of the system’s USB ports.
The only configuration available for the serial port is flow control. Flow control changes the rate of data
transfer over the cable. Some communication settings are static and cannot be changed. The static settings
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.
