Step by Step
Configuration
Note: When the Raven is used
for circuit switch, the circuit
switch configuration will disable
all ALEOS features except for
serial port communication.
Rev 3.0B Feb.08
Circuit‐switch communication requires the Raven to be in
PassThru mode, communicating directly with the internal
hardware.
PassThru mode disables the use of ALEOS in the modem. Any
features available using ALEOS are not usable when the
modem is in PassThru mode. In PassThru mode, the settings
available are those of the internal hardware. The Raven N3213
in PassThru mode can not.
The best machines for use in circuit‐switched mode are ones
that can provide their own INIT or setup strings and/or issue
AT commands. For customers who have unintelligent
machines who still need to have the modem ʹreadyʹ to behave
in a certain way (such as Auto‐Answering circuit‐switched
data calls), there is a feature in the modem called the INIT
STATE.
For iDEN, circuit‐switched configuration requires an account/
SIM specifically configured for a Circuit‐Switched Data (CSD)
plan with no restriction on inbound or outgoing calls. A SIM/
account provisioned only for standard data options will not
work for CSD.
Configuring Circuit-Switch
The Raven needs to be configured to enter into PassThru after
start up. You can use AceManager (preferred) or direct serial
communication to configure the Raven to work in PassThru
mode and for circuit‐switched communications. In the UDP
group, select the MD command and choose 07‐PassThru.
