CAUTION Only connect compatible measurement devices to the transmitter. Attempting to connect incompatible devices or cables can damage the equipment. Refer to transmitter specifications for compatibility information.
Figure 1. Connecting probes and cables to Indigo200
Probes are locked in place with the locking wheel. Never turn from the probe body.
Probe connection cables are connected in the same way as probes: insert the cable in the connector and hold in place while turning the locking wheel.
Probes are inserted into the probe connector with the orientation mark and/or the Vaisala logo facing out.
  1. Insert the probe into the probe connector with the orientation mark and/or the Vaisala logo on the probe body facing out. Note the orientation of the cable connector pins when inserting.
  2. Hold the probe in the probe connector and lock it in place by turning the locking wheel counterclockwise. Never turn the probe body when connecting or removing probes, only the locking wheel of the transmitter.
  3. If no previous configuration exists (that is, this is the first time a probe is connected to the transmitter, and no configuration has been set manually), the transmitter adapts the analog output settings of the connected Vaisala Indigo-compatible probe automatically.
    If a configuration that differs from the connected probe's configuration exists in the transmitter, you must configure the new probe manually to enable the analog output.
  4. When the transmitter recognizes the connected probe, it shows a notification message on the display (for example, Probe Connected: GMP251). In the non-display model, a green LED is lit when the transmitter recognizes the probe.
