ATMOSPHERE VALUE
(Convection Boards) Sets the Atmosphere value to be used in Convection gauge calibra-
tion. See “Main Screen” on page 25 for the calibration procedure.
SERIAL MODE Select between RS232 and RS485 communications.
When RS232 or RS485 is selected, the communication protocol is
ASCII (see “ASCII Serial Commands” on page 67) and the only dif-
ference being the use of either the RS232 or RS485 transceivers.
With the XGS-600 BCD communication is a packed-BCD type
using only the RS232 transceiver. This protocol is described in
“BCD Serial Commands” on page 77 and is substantially back-
wards compatible with older Multigauge controllers running Px.x
EPROMs.
SERIAL BAUD RATE Selects between baud rate options: 9600 (default) and 19200.
RS485 ADDRESS Set the RS485 address (default 00) as used in the first two charac-
ters of all serial protocol commands (see “ASCII Serial Commands”
on page 67).
REMOTE INPUTS
ACTIVE WHEN Use this to select either active LO (default) or active HI logic for the
HFIG and IMG board on-off and degas (HFIG only) inputs. When
the input is in the active state, the gauge is turned on. The active HI
selection provides backwards compatibility with Multigauge and
Sentorr applications. See “XGS-600 vs MultiGauge and SenTorr
Backwards Compatibility Detail” on page 63 for a description of
differences.
RESET SCREEN Select to open the Software Versions screen which includes the sys-
tem reset function (page 40).
EXIT Select to return to the Main Screen (page 25).
