Guralp Systems CMG-DM24 - Manual (Page 59)

Operator's guide
If you have already configured a telephone number, the command will
print out the current setting and ask if you want to change it.
+MODEM
Phone# 00441189819056 New number? y/n y
Enter phone# 00441189819943
Phone# 00441189819943 Flash FIFO : Circular Configuration for
dial out ok_DEMO00
+MODEM also changes the transmission mode of the digitizer to
FILING, so that all incoming data is stored in Flash memory ready to
be downloaded. When the dial-out takes place, all new data in Flash
memory is transmitted. By configuring the DM24 to transmit only
triggered streams, you can create a system which “wakes up” on a
trigger, connects to a data centre using the modem, and delivers the
triggered data in near real time.
–MODEM
Syntax: -MODEM
Disables automatic modem dial-out. Note that this command does not
change the current transmission mode so, if you have previously
issued +MODEM, the DM24 will be left in FILING mode.
If you issue -MODEM over a dial-out modem link, you should make sure
you have arrangements already in place for contacting the DM24 by
other means, since the command will cause the connection to close.
+GCFIN
Syntax: input-port +GCFIN
Instructs the digitizer to accept GCF input on either the GPS or the
DATA IN port. input-port can be:
•
1, for the GPS port; or
•
2, for the DATA IN port.
The GCF streams received will be combined with the DM24's own
streams and output with them through the DATA OUT port or saved to
Flash memory, according to the current transmission mode.
Whilst GCF input is active, the normal function of each port (GPS or
console access) is disabled.
