1.4 Manually Clearing Trend Graph History
For older versions of web server firmware that do not have the “Clear Log Data” button, follow the
procedure below.
Trend graph history can be cleared by first powering down the gumstix device, then moving the
microSD card into a microSD card reader on a Linux machine (or any other machine which can read
ext2 file systems) and removing every file except Cleanup.rb in the directory /espec/log/.
The following commands can be run to do this:
Mount [microSD device] [mount point]
cd [mount point]
rm espec/log/chamber_*
Unmount the micro SD card and return it to the gumstix device.
Note: Many modern Linux distributions will mount the microSD card for you and put a link
to it on your desktop.

1. Make sure that all cables and connections are made properly for the web server option.
2. Turn on power to the test chamber, which will apply control power to the SCP-220 controller and the
web server device.
3. Turn on the P-300 HMI.
4. After about 30 seconds, you should see the communications light under the P-300 HMI start to blink. It
should blink on and off once about every 60 seconds after RS232 communications has been estab-
lished between the SCP and the web server.
5. Connect a PC directly to the Ethernet port on the chamber, using a cross over cable.
6. Start the PC directly to the Ethernet port on the chamber, using a cross over cable.
7. After about another 30 seconds (following step 4), you should start to see the green LED on the Ether-
net connector for the gumstix turn on solid and the yellow LED should start to blink. If these LEDs are
not correct, turn off chamber power and go back to step 1 of this process (check all cables and connec-
tions). If you still can’t get the Ethernet port comms to work, call service for help.
8. Enter the following IP address into the web browser on your PC http://192.168.0.83/.
9. The web server should open up the main page, and it should show the status of the chamber on the
right status bar of the web page (as shown below).

2.1 Web Controller Configuration
2.1.1 Introduction
The web controller configuration screen is split into two main sections, as shown below. The top section of
the screen is used for manually entering the individual configurations, while the bottom section of the
screen can be used for loading standard preset configurations and other various functions. You have the
option of manually selecting the individual configurations that you need, or you can select a standard
preset; which will automatically load standard parameters that are used by many ENA standard test
chamber models. In order to use a preset, skip the instructions in section 2.1.1, and go directly to the Load
Preset Instructions in the “Web Controller Configuration Procedure” on page 11.
10 P-300 Web Controller Configuration and Troubleshooting Manual
The first step in the web controller configurations process is to find out the details for all of the various
configurations and record them for use during the config procedure. Fill in the following data chart for the

2.1.2 Web Controller Configuration Procedure
1. Navigate to the web controller setup page, and click on the “Configure web controller” button. When the
dialog box asks for the configuration password, enter “4141” and click the OK button.
2. The initial preference for configuration is to use a configuration “preset”. You need to know the model
type of your chamber (EP, EGN, EN, etc.). Click on the “Load Preset” dropdown (shown below) and
locate your chamber in the list. Make sure to select the correct line item, based on whether or not your
chamber has product temperature control and if it has low humidity or ultra low humidity options.
3. If your exact chamber is in the list, continue to step #4. If your chamber is not on the preset list, skip to
step #5 so that you can load the configurations manually in the “Edit config” area of the web page.
4. Click on the appropriate preset and wait for the web server to load the data. A message box that says
“Loaded preset to configuration file” will appear when the configuration data has been loaded. Click the
OK button to dismiss the box. Now, go to step #10 to complete the configuration process.
5. Using the “Polling interval” numeric data box, select the polling interval you wish to use for data collec-
tion with the web server. Manually type the data collection interval in the edit box, or use the plus and
minus buttons to change the value one second at a time. This interval time is directly related to the
amount of data that the web server can store, as detailed below.
10 second interval - 3 days of data storage
30 second interval - 9 days of data storage
60 second interval - 18 days of data storage
120 second interval - 36 days of data storage
6. Click the appropriate “on” or “off” radio button for “Product control”. This value corresponds to item #4
from the data chart that you filled in at the start of this process.
7. Click the appropriate “on” or “off” radio button for “Humidity control”. This value corresponds to item #2
from the data chart that you filled in at the start of this process.
12 P-300 Web Controller Configuration and Troubleshooting Manual
8. If your chamber does not have humidity, skip this step and go directly to step #10. If your chamber does
have humidity, you will need to select the appropriate temp-humidity graph file in the “Graph file” area,
which is found directly below the “Polling Interval” edit box. Click on the “Graphical selector” button to
bring up the graphical selection window shown below.
Click on the humidity graphic you want to use. The graphical selection window will automatically close,
and the graphic file you have chosen will be listed in the “Graph File” drop down box to the right of the
“Graphical Selector” button. Alternatively, you can select the graphic image file name directly by using
the graph file drop down box; if you can identify the graph file by name alone.
9. After verifying that all of the configurations are correct, click the “Save” button to send them to the web
controller. After a few moments, a message box will appear to confirm that the new configurations have
been saved to the web controller.
10. Click the “Reboot chamber controller” button at the bottom of the page to complete the process. After
waiting for a few minutes, the web controller should be booted back up with the new configuration; and
you can validate the changes you made by viewing the other standard web controller screen pages.
