Passthru Mode - Sierra Wireless Raven EDGE User Manual

Data Communication and Host Modes

PassThru Mode

In PassThru mode, the Raven does not behave normally, all
port communication is passed directly between the internal
hardware and the computer connected directly to the modem.
This mode can be used to configure hardware‐specific settings.
For example, provisioning, troubleshooting, communicating
with legacy equipment, etc.
Caution: ALEOS is disabled in PassThru Mode. You cannot use
most ALEOS specific commands while the modem is in PassThru
Mode. While in PassThru mode, you also cannot use AceManager to
connect with the PinPoint.
Issuing the "AT\APASSTHRU" from a terminal emulation
enters this mode. The modem responds with OK, at which
point a direct connection to the internal hardware is estab‐
lished. You can also configure the modem to enter PassThru
mode on start up using MD.
Tip: PassThru can only be exited by resetting or power-cycling the
modem. This mode cannot be entered via a remote Telnet session.
You can configure a string of AT commands to be sent to the
Raven when it enters PassThru and other PassThru settings.
Figure 6-1: AceManager : PassThru
PassThru Mode allows only specific AT commands. Some
ALEOS commands will be unavailable when the Raven is in
PassThru mode. The commands usable also depend heavily on
the modem model number (found on the label on the top of
the Raven).
Note: Some internal hardware requires upwards of 20 seconds
before AT commands can be entered, so be patient if there seems to
be no response to AT commands.
