Serial Communications Overview
ULTRA 100 Series drives communicate via a standard NRZ (non-
return to zero) asynchronous serial format, which supports either RS-
232 or four wire RS-485. The pin-out arrangement on the drive serial
ports provides self-sensing of the communication standard. To change
from RS-232 to four wire RS-485 requires a simple change of the
cable.
In multiple drive installations, a unique address must be assigned to
each drive through software. The factory default drive address is
setting is Address 0. All addresses changes are made through
ULTRA Master software selection. Up to 32 (1 through 32) are
supported.
Each drive may be assigned a unique name of up to 32 characters in
length; a name is often easier to remember than the address of a drive.
ULTRA Master software automatically associates a drive name with
the correct drive address.
RS-232 Connections
The address of each drive is set using ULTRA Master software. Refer
to the ULTRA Master on-line Help.
