Block Diagram DataTalker Owner’s ManualChapter 1 - Introduction and Description communications software to the DATA/COMMAND connector on the back panel and configure the data channel for the type of data that is going to be transferred. 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 LinkChapter 1 - Introduction and Description 1.4.6 Diagnostics1.4.7 Operational Statistics 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 IntroductionHome Office 2.2 Configuration 1 - Dial-Up LinkChapter 2 - Configuration DataTalker Owner’s Manual To configure the DataTalker, enter 1 and press ENTERATDTNumber to DialN0 CR AT$D1 CR AT&W CR Q CRChapter 2 - Configuration 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.
