Configuring to Connect to a Mobile Phone
If you want the CK1 to transfer information through a mobile
phone connection, use the mobile phone cable (P/N 073351) to
connect the CK1 to a mobile phone with a PC connect cable.
Your application must be set up to:
• communicate with the mobile phone.
• turn on the ext 5 Volt in the connection with the CK1.
• detect if the CK1 is sending or receiving data through the
connection and turn off the connection if no data is being
transferred. Turning off the connection prevents you from
being charged for phone time when no data is being
transferred.
For help creating applications, see Chapter 3, “Developing and
Using Applications.”
You also need to subscribe to a data transmission service for your
mobile phone. For help, contact your mobile phone service
provider.
The following procedure explains how to configure the CK1 to
dial up over either a modem or null modem connection.
To configure and connect the phone connection
1
Connect a mobile phone cable that is connected to a mobile
phone to the CK1 I/O connector, or place the CK1 into a
modem dock that is connected to a phone jack and power
outlet.
2
Turn on the CK1.
