RS485/RS232

Note: Many laptop computers have external RS232 serial ports which require
converters to change to RS485 to connect to the Multi Unit. When using a self
powered RS485/RS232 converter (Telebyte #253-PP2 www.telebyteusa.com),
communication errors may occur due to the loss of power during communication to
large numbers of spindles. In this case, use a powered converter or direct RS485
communication.

If your laptop does not have a RS232 card, it is recommended that a PCMCIA Serial
RS232 or RS485 card be used. (ie. www.socketcom.com)

We do not recommend USB RS232 converters. Many of these converters in the
market will not operate correctly using this system.

Note: In order for the Multi Unit to communicate properly to the SAN (Servo) Units,
the spindle(s) address DIP Switch must be set correctly. No two units may share the
same address, however, unit addresses may be skipped or started from a number
besides #1. If units are skipped, the missing spindle addresses MUST be removed
from the programmed fastening sequence or an abnormal will result.
