TEMPERATURE DISPLAYS
A sensor fault condition is identified by a display of
a clipping or clamping message. This usually
indicates that the sensor is open, disconnected or
shorted.
If a temperature reading is within the measurement
range of the instrument but is not within the
specified Sensor Calibration Curve, a display of
seven dot (.) characters is shown.
LED INDICATORS
There are three LED indicators below the display. They indicate the
following:
Alarm
(Red) – An enabled alarm condition is asserted.
Relay 1
(Green) and
Relay 2
(Green) - Relay asserted.
Latched alarms and relays are cleared by pressing the
Enter

ETHERNET COMMUNICATION
An Ethernet connection can be established by using a standard RJ-45
patch cable. The monitor acts as a server with a default IP and subnet
mask is
192.168.1.4
and
255.255.255.0
. The user can change this from
the front panel via a menu or from a web browser. DHCP can also be
selected.
To view the embedded web page, open a web browser and type the
default IP of 192.168.1.4 in the address bar.
The default port for the TCP server is 5000. The UDP server is at TCP+1.
WEB SERVER FUNCTIONS
Note:
The embedded web server's default user name is
admin
and default password is
cryocon
.
This secure server provides most of the functions required to view and
configure the instrument including the downloading of user-defined
sensors, real-time strip-charts, data-logging and firmware updates.
