Wired Configuration – AVW200 with Direct Connect Gages
The following configuration depicts an AVW200 connected directly to the CR800 or CR1000, with gages
connected directly (no multiplexers) to the AVW200. Up to 2 gages may be directly connected to the
AVW200. The connection scheme utilizes SDI-12, this allows a single control port connection to the MCU.
Other configurations are possible including use of the RS-232 port. See the AVW200 Operators Manual
for more information on these configurations.
To configure MultiLogger use the following Direct Connect Gage Type | Make | Model selections:

Notes:
• All of these Models use a frequency range of 400-4000Hz which should be adequate for most
installations. Contact Canary Systems for direction to narrow or widen the frequency range.
• All of these Models use SDI-12 address 0. Contact Canary Systems for direction when using a
different SDI-12 address.
