Connecting to the PC using RS-232
• Locate your computer within 6 feet of the BLU servo 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 RS-232 jack on your drive. Secure the adapter to the
PC with the screws on the sides.
Never connect a BLU servo drive to a telephone circuit. It uses the same connectors and cords as
telephones and modems, but the voltages are not compatible.
If your PC does not have a serial port, you should purchase a “USB Serial Converter”. We
have had good results with the Port Authority “USB Serial DB9” Adapter from
CablesToGo.
com
and with the SW1301 from
SewellDirect.com
.
For laptops, a PCMCIA converter card is a good choice. Our applications engineers use the
SSP-100
from Sewell Direct.
Regeneration LED
This LED indicates when the drive is actively applying the regeneration clamp. The clamp is
the internal circuitry that shunts the DC bus to a power resistor. The power resistor can be
either internal or external. (See “
Servo Drive Regeneration
” in this manual for more details)
