    The Address Resolution Protocol (ARP) is used with the IP protocol for mapping a 32-bit Internet Pro- tocol address to a MAC address that is recognized in the local network specified in RFC 826. Once recognized the server or networking device returns a response containing the required address. Available for MS-Windows 9x, ME, NT, 2000, XP, and Win7.

  • Page 89: Appendix 1 - "Officer Requires Assistance" Alarm Function

    APPENDIX 1 – "OFFICER REQUIRES ASSISTANCE" ALARM FUNCTION Overview The DTE Port Interface pin 9 (AUX) on DEV-2 is used for the alarm function. “Officer Requires Assistance” Intended Audience This appendix is designed for use by System Integrators. Physical Connection This auxiliary input may be activated by (normally open) dry contact pull-up to the port’s DSR output (pin 6).
  • Page 90 Operation When using GeminiG3 product running firmware version 2.1 or later, activating the “Officer Requires Assis- alarm input starts emergency communications: tance” • On systems using DMP-transition facilities, the modem sends a DMP “x” or “y” message through to the MSC2 to the Host PC.

  • Page 92: Appendix 3 - E-Dba Throughput/Latency Measurements Methods

    Because of E-DBA’s cycle mechanism, a ping packet could take up to 3 cycles to make the round trip, producing an unexpectedly large ping time even when the radio channel is lightly loaded. For this reason, CalAmp recommends that ping should only be used to verify if a device is reachable, not as a measure of network performance.

  • Page 94 Conclusion Although some standard tools such as the ones outlined above can be used to get a rough idea of an E-DBA sys- tem's performance, the best metric will always be to test the system in conditions that reproduce as closely as possible its real-life usage.
