    Replacing the Tait T2000-A81 Board This chapter describes the issues regarding the transfer from a combination of Tait 2000 radio and T2000-A81 board to the TM8000 mobile radio. It will also help integrators who are considering interfacing an external product to the TM8000 auxiliary connector.

  • Page 118: Configuring The Tm8000

    As the TM8000 is a highly configurable radio in terms of digital I/O, multiple PTT line control and audio tap in and out points, familiarise yourself with the programming application. Note Tait Electronics can provide a training module that covers this area. Table 6.1 describes the T2000-A81 connections and a suggested arrangement for using the TM8000 lines for a similar application.
  • Page 119 The BCD signal lines referred to in the table relate to V2.05 firmware for the T201X only. I/O pads are provided on S15 for linking in the case of other T201X firmware variants.
