    600 ohm generator impedance. To establish a balanced connection between RM2042 and the connected VHF radiotelephone, it will be necessary to use two wires, while an unbalanced connection only requires one. Because the number of wires in the connection cable is limit to nine and all are in use, it is necessary to change the function of the serial data bus and use this as the second wire in the balanced connection.
  • Page 58 If the power supply is completely lost, the RM2042 will simply be turned off and when the power supply is re-established, the RM2042 will be restarted by a power on reset pulse, generated at the microproc- essor module.
