Table 7-10. Data Port Configuration

Step Procedure

1Toggle DIP switch position 3 to the down (closed) position to enable the command port.

2Connect a terminal or PC running communications software to the DATA/COMMAND connector on the back panel of the DataTalker.

Note: Any cables connected to the computer should be shielded to reduce interference.

3Apply power to the DataTalker.

4Apply power to the terminal or PC. Run the PC’s communications software in terminal mode and press ENTER twice to establish communications with the DataTalker. The Main Menu appears:

For example, if an asynchronous device is going to be connected to the data channel, you must set the speed of the channel, the word length, the number of stop bits, whether or not you are going to have parity checking, the flow control type, and other aspects of asynchronous data. After you have configured the data channel, remove the command port device and connect the data channel device, allowing data to be transferred from the asynchronous device to the MultiMux’s input/ output circuitry1.4.1 Voice/Fax 1.4 System Features1.4.2 Data Channel 1.4.3 Composite Link1.4.6 Diagnostics 1.4.7 Operational StatisticsChapter 1 - Introduction and Description DataTalker Owner’s Manual 1.5 FCC Regulations for Telephone Line InterconnectionChapter 1 - Introduction and Description 1.6 Canadian Limitations Notice1.7.3 System Control Command Port 1.7 Specifications1.7.1 Async Data Channel 1.7.2 Sync Data Channel1.7.6 Internal DSU 1.7.5 Internal Modem1.7.7 ISDN Terminal Adapter 1.7.8 Voice/Fax ChannelDesktop Models 1.7.9 Electrical/PhysicalRack-mount Models DataTalker Owner’s ManualChapter 2 - Configuration Valid Voice/Fax Configurations DataTalker ConfigurationsConfiguration 2.1 Introduction2.2 Configuration 1 - Dial-Up Link Chapter 2 - ConfigurationHome Office DataTalker Owner’s Manual To configure the DataTalker, enter 1 and press ENTERAT$D1 CR AT&W CR Q CR Chapter 2 - ConfigurationATDTNumber to DialN0 CR DataTalker Owner’s Manual To connect the home office DataTalker to its PC, connect an RS232C cable between the DATA/ COMMAND connector on the DataTalker and an async port on the PC typically, COM1 or COM2.
