  • Page 12: Configuration

    CHAPTER 3: Configuration 3. Configuration The Sync SHM-NPR MP has seven configuration switches, which allow selection of carrier control method, clocking method, RTS/CTS delay, and data rate. This section describes switch locations and explains all possible switch configurations. 3.1 Switch Locations...

  • Page 13: Switch Settings

    SYNC SHM-NPR MP Figure 3-2 shows the orientation of the switches on the SIP, including ON/OFF position. Figure 3-2. Close-up of Configuration Switches. 3.2 Switch Settings All possible settings for the Sync SHM-NPR’s configuration switches are presented in Table 3-1. If you have additional questions about configuration, contact technical support.
  • Page 14 CHAPTER 3: Configuration 1: N WITCH 2: C WITCH ARRIER NABLE Use switch 2 to specify how the carrier signal is raised. In most point-to-point, full-duplex applications, the carrier signal can remain constantly “high.” In a multipoint environment, contention for the line is controlled by RTS.
  • Page 15 SYNC SHM-NPR MP 5: RTS/CTS D WITCH ELAY After the host terminal raises a request to send (RTS), the SHM-NPR raises CTS after a slight delay in order to give the remote terminal time to receive an incoming signal. Depending on the type of environment, either a 7- or 53-ms delay can be selected.

    4. Installation Once the Sync SHM-NPR is properly configured, it is ready to connect to your system. This section tells you how to properly connect the Sync SHM-NPR MP to the twisted-pair and RS-232 interfaces, and how to operate the unit.

  • Page 17: Or Rj-45

    SYNC SHM-NPR MP For your convenience, the Sync SHM-NPR is available with three different twisted-pair interfaces: RJ-11 jack, RJ-45 jack, and terminal blocks with strain relief. 4.1.1 T RJ-11 RJ-45 WISTED ONNECTION SING The RJ-11 and RJ-45 jacks on the SHM-NPR’s twisted- pair interface are pre-wired for a standard telco wiring environment.
  • Page 18 CHAPTER 4: Installation When you connect two SHM-NPRs, you must use a crossover cable. Figure 4-2 shows how you should construct a crossover cable for an environment where both SHM-NPRs use a 6-wire RJ-11 connector. Use a similar method when you use an RJ-45 connector or a combination of both RJ-11 and RJ-45.
