Conduct a MultiHop Site Survey (from the LCD Menu System)

Perform the site survey before permanently installing your network to pre-screen a site for its radio communication potential,

compare link quality in different locations in a factory, or assist with final antenna placement and aiming.

Site surveys can be conducted from either the master, repeater, or slave radios. A master radio is always a parent and the slave

radios are always children radios within the radio communication relationship. A repeater radio, however, may be both a child radio

to the master or another repeater and a parent radio to other repeater or slave radios. For a more detailed description of the parent-

child relationships, refer to the device data sheets.

Site Survey

Site Survey

Other radios bound within the same network remain synchronized to the network, but are blocked from sending data while the site

survey is running. The site survey analyzes the signal strength between the selected child and its parent radio only. Disable site

survey on one radio before initiating it from another.

Radios in site survey mode have a solid green LED for the duration of the site survey and the LCD display scrolls the results.

Because the statistics represent the lesser of the round-trip results, one person can ascertain the link quality from either device.

Single-click button 2 to pause or resume autoscrolling the site survey results. While paused, button 1 single-step advances through

the four signal strength categories: green, yellow, red, and missed. Double-click button 2 to exit the results display. (Refer to the data

sheet for the menu structure.)

1. On a MultiHop radio, press button 1 until the display reads *SITE.

When the site survey runs, serial and I/O data radio communication between that parent and its children stops.

2. Single-click button 2 to enter the Site Survey menu.

Master radio: The displays reads CHLDRN. Repeater radio: The display reads PARENT. Slave radio: The display reads

PARENT.

3. Select the MultiHop radio to analyze.

MultiHop Model

Select the radio to analyze:

From the master

radio

Single-click button 2 to display the child radio’s device address. (A radio’s device address is

displayed under its *RUN menu). Single click button 1 to scroll between all the master radio’s

children. When you reach the child radio you want to run the site survey with, single-click button 2.

From the repeater

radio

Single-click button 1 to cycle between PARENT and CHLDRN. Single-click button 2 to select

PARENT or CHLDRN. If conducting the site survey with one of the repeater’s children, single-click

button 1 to scroll among a repeater’s children radios. (Each data radio’s device address is displayed

under its *RUN menu.) Single-click button 2 at the device address screen to select the child or parent

and begin the site survey.

From the slave

radio

Single-click button 2 to display PARENT. Single-click button 2 to begin the site survey.

The site survey begins. LED 2 on both the parent and child radios flash for every received RF packet. To indicate the parent

is in site survey mode, LED 1 is a solid green. The data radio analyzes the quality of the signal between the parent and child

by counting the number of data packets received and measuring the signal strength (green, yellow, and red).

4. Examine reception readings (G, Y, R, M) of the devices at various locations. M displays the percent of missed packets while

G, Y, and R display the percent of received packets at those signal strengths. These values are continuously updated as

long as the site survey is running.

GRN = GREEN excellent signal strength; YEL = YELLOW good signal strength; RED = RED marginal signal strength; MIS =

Percentage of missed packets. When possible, install all devices to optimize the percentage of YELLOW and GREEN data

packets received.

5. While the site survey is in process, single-click button 2 to pause or resume autoscrolling the site survey results. While

paused, button 1 single-step advances through the four signal strength categories: green, yellow, red, and missed. Double-

click button 2 to exit the results display.

6. Double-click button 2 on either the child or the parent device.

Site survey ends and the devices automatically resume operation.

Configuring the Ethernet Radio Using the Web Tool

The Ethernet Data Radio is typically configured using the hardware DIP switches on the side of the device. It is not necessary to

access the software configuration to create a Ethernet wireless network.
