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 circuitry Chapter 1 - Introduction and Description1.4.2 Data Channel 1.4 System Features1.4.1 Voice/Fax 1.4.3 Composite Link1.4.6 Diagnostics 1.4.7 Operational StatisticsChapter 1 - Introduction and Description 1.5 FCC Regulations for Telephone Line Interconnection DataTalker Owner’s Manual1.6 Canadian Limitations Notice Chapter 1 - Introduction and Description1.7.1 Async Data Channel 1.7 Specifications1.7.3 System Control Command Port 1.7.2 Sync Data Channel1.7.7 ISDN Terminal Adapter 1.7.5 Internal Modem1.7.6 Internal DSU 1.7.8 Voice/Fax ChannelRack-mount Models 1.7.9 Electrical/PhysicalDesktop Models DataTalker Owner’s ManualChapter 2 - Configuration Configuration DataTalker ConfigurationsValid Voice/Fax Configurations 2.1 Introduction2.2 Configuration 1 - Dial-Up Link Chapter 2 - ConfigurationHome Office To configure the DataTalker, enter 1 and press ENTER DataTalker Owner’s ManualAT$D1 CR AT&W CR Q CR Chapter 2 - ConfigurationATDTNumber to DialN0 CR 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.
