Only the PMA-02 meter copy cable must be used for meter-to-meter interfacing.
  • Page 87 Analog Panel Meter Instruction Manual Meter Copy or Cloning Instructions Do not connect the two meters to the same signal source while cloning. Internal calibration may Caution! be affected. Connect two meters using a PMA-02 meter copy cable. Use PMA-02 meter copy cable only! Using standard CAT5 or other cable will cause damage to both meters.
