Set up the main office unit to use the default composite link settings. Set up the home office unit for DTR dialing. To set up for DTR dialing, select option 1, Enter AT Commands to 2834, and enter the following AT commands:

ATDT[Number to Dial]N0 <CR>

AT$D1 <CR>

AT&W <CR>

Q <CR>

ATDT[Number to Dial]N0 is the AT command to store the main office phone number in location N0. The AT$D1 command sets the modem for DTR dialing when the home office DataTalker is powered up. The AT&W stores the $D1 command as a user default. The Q command returns you to the Composite Link Settings menu. <CR> is shorthand for a carriage return (press ENTER). Enter S and press ENTER to store the new configuration.

This completes the configuration of both DataTalkers. The main office DataTalker can now be connected to the host computer, PBX, and phone line. The home office DataTalker can be taken home.

To connect the main office DataTalker, first disconnect the PC or terminal from the DATA/ COMMAND connector on the DataTalker. Place DIP switch position 3 in the OPEN (up) position to change the data/command port over to the data channel. Connect an RS232C cable between the DATA/COMMAND connector on the DataTalker and an asynchronous port on the host computer. Connect an RJ-11 phone cable from the VOICE/FAX CHANNEL 1 FXO connector on the back panel to the station side of the PBX. Connect an RJ-11 phone cable between the DIAL- UP jack on the DataTalker and the dial-up phone line.
