DIP switch for setting USB functionality OFF or ON
To switch USB communication or RS-485 termination OFF or ON with the DIP
switches:
To avoid damaging the connector pins of the transmitter, pull the
transmitter cover off the base in a straight angle. Do not twist or bend.
Use a small screwdriver or a similar tool to change the position of the DIP switch to
OFF or ON.
When done, close the transmitter cover and power on Indigo. Note that when the USB DIP
switch is in the OFF position, the transmitter USB port is inactive and it is not possible
to connect Indigo202 to Insight PC software for configuration.
