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
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.
