B: Circuit Switch Communications B
•Step by Step Configuration
•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.
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 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.
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.
