Connecting to the PC using RS-232
• Locate your computer within 8 feet of the drive.
• Your drive was shipped with a communication cable. Plug the large end into the serial port of your PC
and the small end into the PC/MMI jack on your drive. Secure the cable to the PC with the screws on the
sides.
CAUTION
1. Never connect a drive to a telephone circuit. It uses the same connectors and cords as
telephones and modems, but the voltages are not compatible.
2. Drive ground and PC ground should be at the same potential. Different ground potentials
for the drive and PC can result in excessive current through the ground pin of the RS-232
port, resulting in failure of the port.
If your PC does not have a serial port, you should purchase a USB-serial converter to convert one of your
PC’s USB ports into an RS-232 (COM) port.
For 32-bit Windows operating systems, we have had good results with the Port Authority “USB Serial DB9”
Adapter from
and with the SW1301 from
For 64-bit Windows operating systems, namely Windows Vista 64 and Windows 7 64, the Prolific-based
adapters listed above do not work. For these PCs we suggest the USB-COMi-M or USB-CBL from Byterun-
ner.com. These adapters also work the 32-bit operating systems.
For USB choices, refer to page 52.
