Triggering Binding Mode On A Gateway From A Host System - Banner Sure Cross DX80 Instruction Manual

Sure Cross Radio Networks and Host Controller Systems
When Site Survey runs, the accumulated results are stored in the Gateway's I/O 7 and I/O 8 holding registers. The LEDs on
the both the Gateway and the Node's front panel display the signal strength for the wireless RF link. The quality of the
communications link is indicated by:
Green LED = excellent signal strength
Amber LED = good signal strength
Red LED = poor signal strength
The signal strength is the transmitted signal strength relative to the ambient RF signal present in a specific location, or noise
floor.
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).
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 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]).
7.5 Triggering Binding Mode on a Gateway from a Host
System
To use a Modbus host controller system to trigger binding mode on the Gateway, the Gateway's LCD version must be 3.2A
or higher To use a Modbus host controller to enter binding mode:
1. Write one of the following values to the Gateway's register 6371.
Value (dec) Action
256 Gateway enters binding mode, but doesn't assign a Node ID
257 Gateway enters binding mode, assigns ID 1 to the Node it will bind to
258 Gateway enters binding mode, assigns ID 2 to the Node it will bind to
... ... for up to 47 Nodes
The Gateway enters binding mode. If 256 was used, the Gateway does not assign a Node ID. If any other listed
number is selected, the Gateway enters binding mode and will assign that Node ID to the Node it binds to.
2. Verify the Gateway's LEDs flash red alternatively. For board module Gateways, the LED flashes green and red
alternatively when in binding mode.
To disable binding mode, write a 0 to register 6371.
