  • Page 9: Functional Description

    Functional Description The TKH Security USA Model 9522A is an RS232, RS422, and RS485 compatible fiber optic standalone modem with dual electrical I/O ports and dual optics for drop and insert applications that can be configured in a wide range of poll/response network architectures. The unit operates using only one fiber for transmit and receive in the upstream direction and a second fiber in the downstream direction.

  • Page 16: System Architecture

    System Architecture The Model 9522A can be configured into three basic network architectures with almost unlimited variations. Variations include unlimited branches from the main trunks. Typically the rack-mountable Model 9522A or 9522AY are used at a central hub. Standalone Models 9526AY and 9526A are used at the remote (local) locations.
  • Page 17 Local Daisy Chain (LDC) Mode In this mode, there is a specific "upstream" and "downstream" data direction, because data is only transmitted to or from the master rather than in both directions as on a ring. Specifically, the TX1/RX1 port communicates upstream with the master controller and the TX2/RX2 port communicates downstream with the next modem on the daisy chain.

  • Page 19 With this architecture, one master controller lies at the end of one or more main trunks. In all cases, a Model 9522A set in Master Daisy Chain Mode will be used as the master modem. A branch can be configured off the main trunk by connecting another modem to an unused data port of a modem on the trunk and building a daisy chain from that modem.
  • Page 20 (Refer to Figure 6) AISY HAIN WITH ASTER ONTROLLERS With this architecture, master controllers lie at both ends of one or two main daisy chain trunks. In this application, the local modems in the "daisy chain" trunk operate in Local Fault Tolerant mode because the modems in the daisy chain have to be able to communicate with masters in both directions.

  • Page 22 (Refer to Figure 7) AULT OLERANT EDUNDANT With the architecture of Figure 7, all modems are arranged around a dual counter rotating fiber ring (via one fiber), starting with one optical port of the master modem (operating in Master Fault Tolerant mode), looping through an indeterminate number of local terminal modems (operating in Local Fault Tolerant mode), and terminating back into the second optical port of the master controller modem completing the ring.

  • Page 24 DDITIONAL EATURES In addition to the features already described the following features of operation are incorporated as either basic indispensable functions or as performance enhancements or options. Data Input Anti-Streaming The electrical side anti-streaming feature, when enabled, limits the time that a terminal unit may accept and transmit RS232 input data with a single request-to-send (RTS) enable.
  • Page 25 Priority Select Priority Select is enabled automatically in both Master and Local Fault Tolerant modes (Refer to the section of the manual on Operational Modes). The priority select circuitry automatically selects the data that arrives first via either the TX1/RX1 or TX2/RX2 optical ports. In normal operation, since the master transmits both directions on the ring, each terminal on the ring will receive data from both directions.
  • Page 26 When using this feature, all modems in the network must be Models 9522Y, 9526Y, 9522A, 9521AY, or 9522A. If this feature is disabled, other models such as the 9525Y and...

  • Page 27: Set Up Of The 9522A

    Set Up of the 9522A Preparation of the modem for operation consists of setting the dipswitches for the particular application, making the fiber, data, and power connections. ETTING THE IPSWITCHES  Set the Operational Mode using S1 switches 1 and 2. Refer to Table 1 and to the System Architecture section for more details on selecting the Operational Mode.
  • Page 28  Set the Data Tagging for the Primary Data Port with switch S1-10. If the Data Tagging Feature is enabled, ALL modems in the network must have this feature enabled. If there are modems in the network that do not support this feature, it MUST be disabled. Refer to Table 2 and the System Architecture section for details on this function.
  • Page 29  Set the RS232 Anti-Stream Enable/Timeout. Set S2-1, S2-2, and S2-3 to either disable or select the RS232 anti-streaming timeout. Refer to the Anti-stream Timeout section in System Architecture and to Table 4. Table 4 — Switch S2, Timeout/Streaming Set Up Function Down Down...

  • Page 32 RS422 and RS485 Connections When operation with RS422 or RS485 is required, make the connections as listed in Table 10. In RS422 or RS485 model there are no RTS or CTS control lines. Rather the RTS and CTS signals are internally enabled. The RTS and CTS indicator will always be illuminated when the unit is operated with RS422/RS485 data.
  • Page 33  Alarm Connections. A Form C relay output is available via Pins 14, 15, and 16 of the Secondary Data Port connector. Refer to Figure 11. There are three alarm conditions that will activate the external alarm contacts. 1. In the Master Fault Tolerant Mode, if the master unit does not sense the return of a transmitted data burst on both of its optical inputs indicating a break in the optical ring.

  • Page 34: Operation Of The 9522A

    After the proper set up procedures have been accomplished, the modem should communicate correctly with the controller and the other modems in the network. In the event of problems, make use of the extensive array of indicators available on the 9522A for troubleshooting. Table 11 below provides additional information about the Indicators.
  • Page 35 UNCTION The 9522A has a rudimentary BERT test feature that may be implemented off-line. While the test is being run, no other signals may be introduced to a modem in the network. To run the test, set the Front Panel dipswitch position 2 (center switch), for the TX1/RX1 optical ports or position 3 (bottom switch), for the TX2/RX2 port DOWN, depending on which data path you wish to test.
