•
Autoanswer: enable
(otherwise a connection will never be established)
•
Connect timeout: enable
(otherwise the modem will keep MONITOR awake,
increasing power consumption)
•
Command echo: disable
(otherwise the modem and MONITOR will forever talk
to each other, preventing further connections and increasing power consumption)
•
Telnet mode: enable
(this is required only if using a modem over TCP/IP – if not
enabled, log downloads may fail, especially if using HyperTerminal)
•
Carrier Detect: always on
(also know as LSD Action, DCD, and CD)
•
Baud rate, parity, etc:
set this up to match the settings of MONITOR (defaults
are 115200 Baud, no parity, 8 data bits, 1 stop bit)
Xpert-Xlite Modem 8080-0005
Sutron manufactures a modem (Xpert-Xlite Modem part number 8080-0005) that is
suitable for use with MONITOR. When connecting this modem, make sure to set the
modem's internal jumper for external power AND for either 5V or 12V depending on
which you provide. A null modem is needed between MONITOR and the modem. The
default settings from Sutron for the modem will work. If the settings have been changed,
issue these commands to the modem:
AT&F
ATS0=1
ATE0Q1&D0&W
This is what the commands mean:
AT&F set to factory defaults
S0=1 answer on first ring
E0 don't echo characters
Q1 don't send result codes
&D0 ignore DTR
&W save settings into profile.
Raven Modem
A Raven modem allows you to access the system through the internet. The Raven should
be ordered with a fixed IP address. Using that IP address, you will be able to use
HyperTerminal or other TCP/IP aware communications programs to use the command
line interface. Make sure to place a null modem adapter between the Raven and the
station.
The Raven modem must be configured as follows:
Device Port
3001
Configure Serial Port 115200,8N1
Command Echo
