Interval = 15 minutes, only 2 records will be recorded each hour on the Web

Station Configuration

• Data charges will be determined by Transmission Interval and Format– 15 minute intervals = 96 records per day– 60 minute intervals = 24 records per day

• Transmission Format Sizes– “1 Text” = 108 bytes– “G Binary M” or “H Binary E” = 40 bytes– “I Short Bin M” or “J Short Bin M” = 28 bytes
