Verification (via MasterLink)
To verify that the installation of the integral modem was successful and the instrument is working properly,
obtain a modem link with the instrument using MasterLink software.
• Start MasterLink and select Instrument | Establish Link on the main menu line
• Click the appropriate check box in the Instrument Type above the Site List.
• With the Site List dialog box open, click on Add and enter the required information
• Insure the Site Name, Site Location, Site ID, Site ID 2, Instrument Access Code, Site Phone, and
Modem Port are correct. (Modem Port must be set to “None”)
• Click OK , then click EXIT when completed
• Select Setup | Communications on the main menu line
• Ensure Modem Connection Baud Rate is set to 2400 baud
• Check to see if the correct Connector (Com Port) is selected
• Try making a call to the remote site, even if the Modem Init String blank. If the call fails, most likely the
host modem's profile is incompatible. Refer to Need Help on page 27 for further information on determining
the Modem Init String
• After the Modem Init String has been determined and inserted, select Instrument | Establish Link on the
main menu line
• Select the site entered above (click to highlight)
• Click on the Modem button in the lower left corner Site List window to start the call
• Follow the progress by watching the Traffic Light in the lower left corner of the MasterLink screen
Red indicates: Not Linked to Instrument
Yellow indicates: Trying to Link to Instrument
Green indicates: Established a Link to Instrument
• When the Traffic Light goes green, the status box to the right of the light will indicate the instrument type
and the name of the site. If Site Unknown is displayed, the site ID numbers at item 200 & 201 did not match
any of the Site List entries
• Once linked, click on the red bell (upper right corner) to Display and Clear Alarms.
• To complete the call, select Instrument | Disconnect Link. Verify the Traffic Light goes red
