YSI 6000UPG - Manual (Page 138)

9-10
This option identifies the string necessary for the modem to take the phone off-hook (answer). For
nearly every modem, this string is “ATA” and will not have to be changed from the default value.
After answering a call, the 6000
UPG
can prompt for a password before allowing the caller access.
When entering a password, the user will be prompted to verify the password before it will take
effect. Typing “NONE” at the prompt will remove password protection. If password protection is
enabled, the user will see the following screen upon connection.
After three unsuccessful attempts or after 30 seconds with no input, the 6000 UPG will hang up.
Otherwise the user will resume where they were when last connected.
NOTE: All sonde activity except for unattended sampling is suspended while the sonde is waiting
for a call.
Entering modem mode:
To enter modem mode, exit out of the menu system and return back to the command line. At the
“#” prompt, type “modem” and hit return. After connecting the 6000
UPG to the modem, the
6000 UPG will flash the modem’s DTR indicator light to acknowledge that the modem accepted the
initialization string and is ready to receive incoming connections. If the DTR light does not flash
and you see activity on the modem’s RX (receive) and TX (transmit) indicators, insure that the
modem answers “OK” to the initialization string and that all cables and adapters are firmly
connected.
Exiting modem mode:
To exit out of modem mode, disconnect the 6000 UPG from the modem, attach it with a YSI 6095
MS-8 to DB-9 field cable adapter to your PC and while holding down the Ctrl key type “X” (Ctrl-
X). At the prompt, Answer “Y” confirming the intention to exit modem mode.
