Transmitter Supply
The transmitter supply is used to supply power from the Scanner 3300 to external analog or pulse output devices. The
transmitter supply configuration is done through the web-interface for each analog or pulse input (outputted on the “
P
”
terminal). Keeping in mind that Pulse Input 1, 2, and 3 can be configured to be Analog In 5, 6, and 7, or vice versa.
For each analog or pulse input, the transmitter supply can be set to be always on, always off, or set to warm up the
transducer before powering it. The output of the transmitter supply may also be programmed to 8.5 to 24 VDC for each
of these inputs. This is not limited by the external power supply voltage level (ex. The transmitter power supply can be
programmer to source 24 V, even if the external supply to the scanner is only 9V). If no transmitter power is required, the
transmitter power may be disabled for all inputs.
