3.3.1Frame Ground Connector (GND)

Use the GND connector to connect the DataTalker frame ground to the PBX’s frame ground when the DataTalker is configured for E&M operation. (The frame ground connector for the rack version is on back of the RackTalker rack.)

3.3.2POWER Connector

The POWER connector shown in Figure 3-2 is the receptacle for the DC power module supplied with the desktop DataTalker. The rack-mounted DataTalker has an AC power connector that plugs into the power bus on a Multi-Tech RackTalker rack when the DataTalker is inserted.

3.3.3DATA/COMMAND Connector

Use this female DB-25 connector to connect the DataTalker to a data channel device such as a terminal, PC, or router, or to configure the DataTalker in command mode. The data channel device can be synchronous or asynchronous. In command mode, an ASCII terminal or a PC with a serial port can be used to configure the DataTalker. The connector’s function (data or command) is determined by the position of DIP switch position 3.

3.3.4EXTERNAL COMPOSITE RS232C/V.35 Connector

Use this male DB-25 connector to connect to an external modem, DSU, ISDN terminal adapter, or any device that is synchronous, full duplex, and supplies clocking signals on pins 15 and 17. The connection interface can be either RS232C or V.35, selected by moving an internal V.35 shunt.

3.3.5VOICE/FAX CHANNEL 1 FXS Connector

Use the FXS (Foreign eXchange Station) connector to connect the DataTalker to an analog station instrument (telephone, fax machine, or key telephone system). The FXS connector is an RJ-11 jack. If a second voice/fax channel is installed, it has an identical connector.

3.3.6VOICE/FAX CHANNEL 1 FXO Connector

Use the FXO (Foreign eXchange Office) connector to connect the DataTalker to a analog station card on the local PBX (Private Branch eXchange). This connection is also commonly referred to as an OPX (Off Premises eXtension). The FXO connector is an RJ-11 jack. If a second voice/fax channel is installed, it has an identical connector.
