Supervisor Set-up
The Supervisor menu provides facilities for programming settings. These are usually made
during installation as follows:
Important Note: A PIN protects the Supervisor menu against unauthorised use. Each
Alarms
An alarm can be set to trigger when the pressure exceeds the high alarm or falls below the
low alarm. A buzzer sounds when the alarm triggers and the alarm symbol (bell) appears on
the display.
Comms
Selects the communication port parameters and simultaneous operation of the RS232, IEEE
488 interface and Ethernet.
Note: PACE1000 Lab view drivers are available for download from:

The user can select appropriate settings for communicating with the control computer (PC)
and the required command protocol.
Referring to the PACE SCPI communications user manual there are three commands that
can be used to retrieve pressure readings from the PACE100X:
:INST:SENS[x]:READ?
:SENS:PRES?
:DISP[x]:WIND?
To obtain fastest readings you must use the following SCPI command :INST:SENS[x]:Read?
This command returns two readings, a filtered reading and a raw reading (unfiltered
reading) from internal sensors, thus giving the user a choice of which reading to use which is
most suitable for their application.
e.g.
TX> :Inst:Sens2:Read?
RX> :INST:SENS2:READ "993.539148733033 993.543837356372"
Note: Raw reading returned from IDOS sensors is "0" as a raw readings cannot be obtained
from IDOS sensors.
Data throughput. Baud rates slower than 115k2 baud will slow the new data update rate
pro-rata. Even at a 115k2 baud rate the readings are slower than using IEEE. IDOS is a slower
sensor than internal sensors.

protecting the supervisor set-up menu the PIN should be changed as soon
as possible.
