External Communications
The computer will need a terminal emulation program to communicate with the remote
multiprobe. Setup the program to provide ANSI terminal emulation, 19200 baud, no parity,
8 data bits, and 1 stop bit for Series 5 Multiprobes. Setup the software to provide a direct
connection to the COM port connected to the modem.
Operating the Modem
Check if the modem is communicating with PC by typing AT and pressing
ENTER. The
modem should respond with OK. To access a remote site from the office, type ATD
followed by the phone number, for example, ATD15122558841. Add the proper prefixes to
the phone number such as 9 (for PBX office systems) or 1 (for long distance). Press
ENTER. The modem should starting dialing the number and negotiating the connection.
Series 5 Mulitprobes may require as long as 15 seconds to show the startup screen. If the
startup screen is not displayed, send a Break by typing
ALT-B. Telephone noise and delay
may prevent the Series 5 Multiprobe from properly determining the presence of an ANSI
terminal. You will not be able to access a Series 5 Multiprobe if logging event is currently
active. This can be avoided by setting the interval to no less than 2 minutes to allow
enough time to call the modem between logging events (a logging event occurring during
a call will not cause a problem).
