  • Page 16: Sdn Theory Of Operation

    SDN Theory of Operation SDN Theory of Operation SDN General Description The Serial Distribution Network (SDN) is a digital communications network designed to share patient physiological parameters and other data among all instruments connected directly to the SDN. The SDN uses cables containing a twisted shielded pair of wires to connect the instruments to the Agilent CareNet Controller (ACC).

  • Page 19: Sdn Topology

    Theory of Operation SDN Topology The SDN uses a star topology that consists of up to 32 individual branches emanating from the center of the star—the ACC. Only one ACC may be used per SDN. One SDN can accommodate up to 24 bedside instruments (one patient per branch), 6 information centers (ICs), and 2 computerized monitoring systems.

  • Page 20: Applications Of Sdn Operation

    Applications of SDN Operation Applications of SDN Operation Configurations of the SDN will vary from installation to installation. The SDN is designed to be flexible enough to accommodate a variety of communication needs in the patient monitoring environment, for the present and for future expansion.

  • Page 21: Sdn Timing Overview

    Theory of Operation the branch cables for instrument-to-system communication via the ACC, and also over the local distribution cable(s) for instrument-to-instrument communication when the local distribution network (LDN) exists. Only one instrument broadcasts patient data at a time and the ACC rebroadcasts that information from that branch to all other branches on the system.

  • Page 22: Autopoll Mode

    SDN Data Structure — System and Instrument Messages Autopoll Mode In the event that the ACC goes down (loses power, for example), all instruments on the same branch continue to communicate with each other in the autopoll mode. Autopoll means that the first instrument (closest to the wall box) sends sync taps and talk taps to itself and the other instruments on the branch.

  • Page 23: Instrument Messages

    Theory of Operation Talk Tap: The talk tap carries encoded information to indicate the branch number and to identify the “autopoll” operating mode. Note Since the status information is block encoded, there is not a one-to-one correspondence between status values and bits of the status words. The condition of these bits are indicated on the status LEDs on the ACC and on the display screens of the SDN instruments.

  • Page 24: Sdn Normal Operation

    SDN Normal Operation SDN Normal Operation This section contains the SDN data timing specifications and a description of the instrument status message. SDN Data Timing Specifications During normal operation SDN digital data travels on the SDN at 3.6 Mbit; the bit cell width is 1/3,600,000 seconds, or 277.78 ns. 277.78ns Bit Cell Width Therefore, the 12-bit word is 3.33 µs long.

  • Page 25: Sdn/Autopoll

    Theory of Operation a. Instrument Identification: Each instrument can be identified as any SDN bedside monitor, IC, or computer. For bedsides the instrument identification gives branch number and type of bedside monitor. b. SDN Communication Error Flags: A variety of SDN system errors are identified and flagged in the instrument status message.

  • Page 26: Acc Error Conditions - Sdn Failure Detection

    SDN Normal Operation ACC Error Conditions — SDN Failure Detection The functional operation of the ACC can be checked and verified to ensure reliable operation. During normal operation, the following LEDs on the Control/Driver PC board are illuminated continuously: RED DS1 (MSB) flickers RED DS4 (LSB)

  • Page 27: Acc Theory Of Operation

    Theory of Operation ACC Theory of Operation The ACC consists of three PC boards (refer to Figure 2-2): • Main PCB • Transition board assembly • Power supply Main PCB (78581-60200) The Main PCB is considered the control/drive board. It connects up to 32 branch cables via the Transition Board to provide timed multiplexed communication links and system synchronization.

  • Page 28: Transition Board (78581-61253)

    ACC Theory of Operation polled at the end of 32 milliseconds must be branch 31 for TALK TAP messages. If not, the poll cycle is in error and an error flag is set in the next SYNC TAP message to indicate a POLL OVERLFOW; for example, system overload or poll sync loss.
