UDP Upload (UDP XFER <- P3)
A UDP Upload transfers a parameter file from the host computer to the 590 Digital drive. This information is written
directly to EEPROM, so all the drive’s current settings will be overwritten.
1. Connect the 590 Digital drive P3 port using the appropriate lead to the host computer.
2. Ensure that the drive's P3 MODE is set to DISABLE.
3. Using a standard communications package, prepare the host computer to send an ASCII file. Set the host
computer's communications port parameters to the settings listed above. Be sure the baud rate setting at both
ends of the serial communications setup match.
4. Start uploading to the 590 Digital drive by selecting “UDP XFER <- P3”
5. When the 590 Digital drive says “RECEIVING”, begin the file transmission at the host computer.
6. The file ends in a :00000001FF which the 590 Digital drive uses to close the file.
7. As the MMI should indicate, reset the 590 Digital drive by pressing the ‘E’ key.

Caution
There is 24 volts on Pin 2 of the P3 Port. This may damage your PC or the 590 Digital drive if
connected to the serial port.
5703 (PEER-TO-PEER COMMUNICATIONS OPTION) SUPPORT
The 5703 Peer-to-Peer Communications Option (catalog No. 655-RS232) passes a 16-bit signal between drives
through a fiber-optic link and the P3 port on each 590 Digital drive. Otherwise, port P3 is used off-line for uploading
and downloading of configuration data. The drive's P3 port operates at RS232 compatible signal levels and the 5703
converts the electrical RS232 signals to fiber optic for transmission over plastic fiber optic cable to a 5703 located at
another drive, then back again for RS232 reception.
Normally, an analog signal setpoint is a used to speed coordinate several drives. The 5703 allows one signal to be
digitally transmitted from drive-to-drive over fiber optic cable. This introduces highly accurate speed setpoint
tracking between drive sections without the signal drift and induced noise problems inherent with analog control. For
accurate speed tracking, encoder speed feedback is required.
