  • Page 12: Rfi-9256 Location

    Placement of your RFI-9256 unit is likely to have a significant impact on its performance. In general, the rule of thumb with RFI-9256’s is that the higher the placement of the antenna the better the communication link. In practice you should also place the transceiver away from computers, telephones, answering machines, and other similar equipment.

  • Page 94 The problem could be at the opposite end of the radio link. For example, if there is a device attached to a remote modem, and the baud rate of the device and modem do not match, you might experience a similar problem. © © © © RF Innovations Pty Ltd, 1998 Page: 92 223889, Revision 2.2...

  • Page 96 Control signal sent by the DCE to indicate that the DTE may begin a transmission. Communications Link When communication is established between modems, information can be passed between them. Signified on the RFI-9256 by both modems having Network Link, Carrier Detect and On-Line LEDs activated and the receive and transmit LEDs flash as data is sent.

  • Page 100 List of information concerning the modem. See Fault Log, Physical Layer Log, and Serial Layer Log. Loop-back Directing signals back toward the source at some point in the communications path. Used in testing RFI-9256. Main Port Port connected to full RS-232 (7 wire) cable. Cable contains Tx, Rx, DCD, RTS, CTS, DTR, and ground. Allows hardware flow control (hardware handshaking).
  • Page 101 On-line Describes the state of a connection as in session and currently connected. The system has dialed and a communications link has been formed allowing the transfer of data. On-line LED on front of RFI-9256 is activated. On-line Requests Timer Controls the time between slave integrity checks by the master.
  • Page 102 One radio (the master) communicates with more that one slave, while each slave can only talk to the master. As opposed to Point-to-Point Communication. Point-to-Point Communication A connection between two points only. Communications established automatically with the RFI-9256 and is not controlled by the AT commands. As opposed to Point to Multipoint Communication.. Port The point of connection, usually a physical connector, between a computer and a peripheral device, another computer or a network.

Simplex Data communications in one direction only. Slave Passive modem. Requires a Master to synchronise timing to enable successful transmission. May initiate communication, but can only communicate with the Master.
