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).
