Sure Cross Performance DX80 Wireless I/O Networks
The Gateway also displays the Site Survey results on the LCD (for models with an LCD). For one transmit and receive
interval, the Gateway saves the lowest signal strength. The LCD and Modbus registers contain the results of the last 100
samples. The totals are a running tally of the last 100 samples and are continuously updated. Four categories are
displayed:
G (green) = excellent signal strength
Y (yellow) = good signal strength
R (red) = poor signal strength
M = Missed packet
To disable Site Survey, send control code 32 (0x20) and Node number 0 (0x0).
3.7.4 Site Survey Data Holding
With Site Survey active, registers I/O 7 and 8 are Site Survey data holding registers that store the accumulated Site
Survey results. Error collections in holding register 8 are saved when Site Survey runs and restored after Site Survey is
disabled.

I/O 7 Red Total
I/O 8 Green Total
NOTE: This is the current register arrangement when using Modbus/TCP or Modbus RTU. In some older models,
the Modbus/TCP registers are reversed (missed and yellow totals are in [8:15], red and green totals are in [0:7]).
