Guardian Co-Deposition Controller Operating Manual
7.3 Guardian Controller Direct Communications
If you prefer to control the Guardian without using the EIES-IV software, you can
create your own deposition control program using these same commands as
described in the following.
NOTE: The Guardian (V4+) only responds to commands received. It never
initiates communications.
7.3.1 Serial Interface
Connect a serial cable from the Guardian serial port to the computer’s serial port.
The cable required is a DB9 female-to-male.
Guardian baud rate is fixed at 115,200. Communications format is No Parity, 8 bits,
1 stop bit.
7.3.2 Ethernet Interface
Connect a cable from the Ethernet connector to your Ethernet network or
computer. Guardian’s default IP Address is 192.168.1.200.
The Ethernet connector on the Guardian controller has two status LEDs:
Top Left (yellow): Link Status
Extinguished: Link not detected. Illuminated: Link detected
Top Right (green): Data Status
Extinguished: No data. Blinking: Data being transmitted or received
7.3.3 Guardian Controller Firmware Versions
Version 4.XX of the Guardian controller is the current firmware version. It is
compatible only with version 4.xx and higher command set and CRC error
checking formatting.
Versions 1.XX and 2.XX are obsolete and must be upgraded to use the commands
documented here.
Version 3.XX and 4.XX use the same command set, but V 3.XX does not include
CRC error checking and is therefore not compatible with version 4.xx and higher
Guardian controller firmware.
Firmware versions 3.XX and 4.XX are covered by this document. See the @
command below for determining the controller version.
