    The type of the generated LF excitation signals depends on the the position of “System” jumpers on the LFA21 and CTL21. For “System S21” jumpers J1 (LFA21) and J3 (CTL21) are to be set on S21 position. The LF excitation signal generated is of type EXID. This signal is a continuous OOK signal on 125 KHz.
  • Page 47 When more than one Exciter EX21 is used to create a wider excitation zone, a magnetic coupling can appear. The phenomenon is explained in Chapter 4, Setup Guidelines in the RFID System S21 Technical Guide.

    Upgrading the Firmware Final Instructions You must repeat this procedure for each Reader RD21 that is installed on the site. Lyngsoe recommends using the RS232 or RS485 4-wire communication line to upgrade the Reader’s software (these are more reliable communication links). For more information on the Reader’s RD21 configuration, see Chapter 5, Configuration and Operation.
