MODEM USE WITH THE VORTEX
After both sides are setup, you should be able to AUTOSCAN from the remote end. Autoscanning will have your modem dial the remote site and connect to the remote modem, which is connected to the Vortex. You can then control the Vortex just like you were connected to it locally.
TROUBLESHOOTING THE VORTEX MODEM CONNECTION
VERIFY THAT THE
VORTEX IS SENDING
THE CORRECT INIT
STRING
On the Vortex side, connect the Vortex RS-232 port to the PC (you may need to remove the null modem adapter). Next, open the CONSOLE window in Conference Composer (right-click on the COMM port in the Explorer menu and choose CONSOLE from the pull down menu) or some other terminal program. Now, send a F**PING command and make sure the Vortex responds with a PONG. This verifies the cable connection between the PC and the Vortex. Now, cycle the power on the Vortex while leaving the terminal window open. When the Vortex reboots, you should see it send the modem initialization string to the terminal window. If you are using the default modem init string, you should see ATE0F1&B1S0=2 echoed in the terminal window. If you don’t see the string, you will need to double check that the string is set cor- rectly and that it is enabled.
MAKE SURE THE INITIALIZATION STRING IS SENT TO THE MODEM
DOUBLE CHECK THE
CABLE BETWEEN THE
MODEM AND THE
VORTEX
If you are sure that the correct modem init string is being sent out when the Vortex reboots, then connect the RS-232 cable between the Vortex and the modem (you may need to add a null modem adapter). Make sure the modem is powered on, then cycle the power to the Vortex. This ensures that the Vortex sends the init string to the modem.
Depending on your serial cable and your modem, you may or may not need a null modem adapter. The Vortex RS-232 port is configured as a DCE. Most modems are also configured as a DCE, so you will most likely need a null modem (The serial ports of most PCs are configured as DTE, which means you don’t need a null modem to communicate between the Vortex and a PC).
