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 circuitry1.4.3 Composite Link 1.4 System Features1.4.1 Voice/Fax 1.4.2 Data Channel1.4.6 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 Notice1.7.2 Sync Data Channel 1.7 Specifications1.7.3 System Control Command Port 1.7.1 Async Data Channel1.7.8 Voice/Fax Channel 1.7.5 Internal Modem1.7.6 Internal DSU 1.7.7 ISDN Terminal AdapterDataTalker Owner’s Manual 1.7.9 Electrical/PhysicalDesktop Models Rack-mount ModelsChapter 2 - Configuration 2.1 Introduction DataTalker ConfigurationsValid Voice/Fax Configurations Configuration2.2 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.
