With the Site List dialog box open, click on Add and enter the required
information. Insure that the Site Name, Site Location, Site Phone,
Site ID, Site ID 2, Instrument Access Code and Mercury Modem
Port are correct. Click OK , then click EXIT when completed.
Next select Communications under Setup on the main menu line.
Insure that the Modem Connection Baud Rate is set for 2400 baud.
Check to see if the correct Connector is selected and that it matches
the port on the computer. Initially, try making the first call with the
Modem Init String blank. If the call fails, most likely the host
modem's profile is incompatible. Refer to Need Help on page 47 for
further information.
Select Transfer on the main menu line or click on the "Phone" Icon
on the productivity bar. With the Modem Link dialog box open,
single click on the site to call, then click on Start Modem Link.
The message at the bottom right hand side of the screen should read;
Dialing XXXXXXX (X=phone number). Once the modems connect,
the message will change to; Linking to Instrument. If the modems
were properly installed, the message will change to green and read;
Linked (Modem).
Both the DOS and Windows verification will activate the LEDs on the
Mercury Modem. The LEDs provide visual feedback for the
following modem operations; Power, Off Hook, Carrier Detect, Tx
to Host, Rx from Host, Port "A" Select and Alarm. To conserve
battery power, the LEDs are not illuminated when the modem switches
to its low-power, standby mode. If configured for alarm call-in, the
modem can call a computer running alarm monitoring software to
report instrument alarms as they occur. If a call fails to connect to the
host system, a call-retry scheme will be executed. An on-board timer
is used to regulate how often the modem tests for low-battery voltage
and alarm retries. Alarm signals from up to four instruments (or
devices) may be connected to the modem using the optional expansion
board.
