Site Visit

Normal Site Visit Procedures

Whenever a visit is made to a MicroMet data site, the following checks should be

performed at a minimum: ( You can capture this session with HyperTerm capture

mode.)

! Connect the PC to the MicroMet at J3. Located at the bottom right most connection

on the MicroMet CPU.

Collect and observe the communication statistics: STAT.

Verify acceptable TX to ACK ratio (less than 10:1).

Verify acceptable SP to SYNC ratio (less than 2:1).

Verify no HIVSWR or LOWPWR.

! Connect PC to CR10X CSIO and run PC208W.

Use NUMERIC DISPLAY to verify sensor acquisition.

Verify CR10X time is correct (Alaska Standard Time), set if necessary.

! Verify proper antenna orientation, solar panel, etc.

Before leaving the site

Before you leave the site it would be a very good idea to:

! Verify that MicroMet communication statistics are normal. Abnormalities include:

1. A high transmit to ack ratio.

2. HiVSWR warnings.

3. Low power warnings.

! Record status and any abnormalities. IE: transmit to ack ratio, etc.

! Verify that the cable connecting MicroMet and the CR10X is properly in place. If this

cable is not in place, no data will ever reach the Master Station.

! Watch at least one data message get acknowledged. (verbose 5) see Warnings

and Advisories, pg 10.

! Canmsg off.

! Take the SC929 CR10X to PC cable with you.

! Take the MicroMet to PC cable with you.
