4.3 Configuration Summary
The following chart shows possible configurations for your DataTalker. Use it as a snapshot of
how your unit is set up. Circle the parameters that apply to your unit. For example, if your unit
has the data channel set up for asynchronous communications, circle “Async.”
Data Port Sync Async
Optional Port None Voice/Fax
Voice/Fax Channel(s) 1 Channel 2 Channels
FXO (PBX) FXS (Phone) E&M (Trunk)
Composite Link Internal Device External Device
External Device RS-232 V.35
Internal Composite Modem DSU ISDN TA

4.4 Data Port Configuration Considerations
When configuring the data port on your DataTalker, the first question you should ask yourself is
what the port is connected to (e.g., an async channel of a host computer, a LAN gateway or
bridge, or the composite link of an MMH900 series MultiMux).
If the port is connected to an asynchronous channel of a host computer, you should
• set the data port to “Async.”
• set the speed of the port.
• verify all the other parameters of the Data Port Configuration menu.
If the port is connected to a dedicated PC serving as a LAN gateway or bridge, the interface is
most likely synchronous and you should
• set the data port to “Sync.”
• set clocking to “Internal” or “External.”
• set the desired speed if you select internal clocking.
• ignore all the other parameters in the Data Port Configuration menu.
If the port is connected to the composite link of a MultiMux MMH900 series, the interface is most
likely synchronous and you should
• set the data port to “Sync.”
• set clocking to “Internal.”
• set the desired speed.
• ignore all other parameters in the Data Port Configuration menu.
