Note: The dial test should be completed with the serial cable disconnected to verify that no signaling is required by the modem.
Circuit Switch Communications
a.Verify that the modem Chan, Link and Reg indicators are blinking in unison confirming that the modem is now operating in circuit switched (IS‐95) mode.
b.Dial the Raven modem telephone number from a land line and verify that the modem automatically answers the call with modem tones.
c.Verify outgoing calls.
1.Connect the modem to your computer with a serial cable. Using a terminal emulation program (HyperTerminal) set up for 9600bps, 8 data bits, no parity and 1 stop bit.
2.Enter the command: ATD[phone number]. For the [phone number], enter a known phone number including the area code for which you can hear ring (such as your office phone).
14.Commission the Raven Modem on Site.
The following steps represent a guideline and makes assump‐ tions that the modem has been verified previously in a controlled environment.
a.Install the Raven modem verifying that all power and antenna cables are correctly secured.
b.Verify that the Raven modem powers up and that the Chan, Link and Reg lights blink in unison.
c.Connect the Raven modem to the laptop computer via a straight through RS232 cable or connect the serial cable from the modem to a USB to serial device that has been previously installed on the laptop.
d.Using a terminal emulation program (HyperTerminal) set up for 9600bps, 8 data bits, no parity and 1 stop bit, verify the signal strength.
For the Raven C3210: Enter the command: AT!RSSI?. This will respond back with a signal strength measure‐ ment represented in dBm. The value must be better than ‐100dBm for the modem to function and it is strongly recommended that ‐90dBm or better be used as a minimum value.
For the Raven C3211: Enter the command: AT+CSQ?. This will respond back with a signal strength measure‐ ment represented on a scale from 0‐31 and second value separated by a comma. The signal strength value must be higher than 9 for the modem to function and it
