RS485/RS232 Command Protocol Summary. (All values must be set in Torr)
Note: This protocol was designed to be 100% compatible with the Helix / Granville-Phillips Mini-Convectron
COMMAND BRIEF DESCRIPTION
READ Read the current pressure in
Torr
SET ADDR Set the communications
OFFSET (RS485) address offset
(upper nibble) *
SET SPAN Set the span or atmosphere
calibration point
SET ZERO Set the zero or vacuum
calibration point
SET TRIP Set the 'turns on below'
POINT #1 pressure point for relay #1
and set the 'turns off above'
pressure point for relay #1.
SET TRIP Set the 'turns on below'
POINT #2 pressure point for relay #2
and set the 'turns off above'
pressure point for relay #2.
READ TRIP Read the 'turns on below'
POINT #1 pressure point for relay #1
and read the 'turns off above'
pressure point for relay #1.
READ TRIP Read the 'turns on below'
POINT #2 pressure point for relay #2
and read the 'turns off above'
pressure point for relay #2.
READ SW Read the revision number of
VERSION the firmware.
SET Force unit to return ALL
FACTORY settings back to the way the
DEFAULTS factory programmed them
