8.1.7.5 Enabling or Disabling Analog Output
When changing the analog output setting, the setting is applied after the transmitter reset.
W
hen analog output is in use
, the serial port does not work but the service connector does.
The 12th bit from left determines if analog output is enabled:
• Analog output enabled at the factory: 0XF,f=1111111111110000
• Analog output disabled at the factory: 0XF,f=1111111111100000
You can enable or disable analog output with the aWU,R= command.
• To enable analog output: Change bit 7 to 1. 0WU,R=1111111111111100
• To disable analog output: Change bit 7 to 0. 0WU,R=1111110111111100
