In "Infrastructure"mode, Wireless Stations normally scan all Channels, looking for an Access Point. If more than
one Access Point can be used, the one with the strongest signal is used. (This can only happen within an ESS).
Is using "Ad-hoc" mode (No Access Point), all Wireless stations should be set to use the same Channel. However,
most Wireless stations will still scan all Channels to see if there is an existing "Ad-hoc" group they can join.
Note: This equipment marketed in the USA is restricted by firmware to only operation on 2.4G channel 1-11

CONFIGURE CLOCKS FOR NTP ONLY
SNS clocks/timers can be configured as Network Time Protocol (NTP) only clocks. In NTP only mode, clocks are synchronized
with an NTP time source. The clocks are not managed or monitored by the AMP platform.
Configuration Overview
During this configuration method:
l
l
l
You first install the Primex Wireless SNS Configuration Tool software on the computer that will be used to configure
the clocks. The SNS Configuration Tool software is located on the SNS Resources CD or can be downloaded from the
SNS .
A local network connection is established between the clock and computer to use the SNS Configuration Tool to
configure the clock settings.
Once these settings are configured, you will initiate the clock’s synchronization with the configured Network Time
Protocol (NTP) server.
Configuration Requirements
NTP only mode requires the clock time source, network settings, and firmware to be configured and managed using the Primex
Wireless SNS Configuration Tool software.
l
l
Primex Wireless SNS Configuration Tool software is installed on the computer that will be used to configure the clock
(s).
PoE models: a Power-Over-Ethernet (PoE) Injector is required or 4 D-Cell alkaline batteries for use during configuration
only (not supplied).
l
Computer
l
Ethernet cable
l
Port 123 UDP (for the NTP time source) is required to be open on the network.

UPGRADE CLOCK F IRMWARE
Each Primex Wireless clock has internal programming, referred to device micro firmware, that controls how it operates. In
addition, the radio installed in each clock has firmware as well. It may occasionally be necessary to upgrade the firmware for
your clocks and/or their radios.
It's recommended to consult with Primex Wireless Technical Support before performing firmware upgrades to validate the
compatibility of devices and firmware versions.
NOTE: Radio firmware versions 4.0.x and greater support the HTTPS or SSL protocol for secure communications over the
network. For additional information, contact Primex Wireless Technical Support.
Upgrade Clock Firmware with the SNS Configuration Tool
You can upgrade firmware for analog and digital clocks, except Personal Series clocks, with the SNS Configuration Tool
software.
In this firmware upgrade method:
l
Primex Wireless notifies you of the availability of a new firmware version.
l
You save the provided firmware file(s) to your computer.
CAUTION: You should only attempt to upgrade an SNS clock with an authorized Primex Wireless firmware file or
you risk rendering your clock completely inoperable.
NOTE: In general, the SNS Configuration Tool is used for the initial configuration of clocks for the network prior to their
installation. In most cases, these clocks should be new clocks with current firmware. Once clocks are installed, you
may use the AMP to upgrade their firmware. For additional information on the Clock Configuration Software Tool,
see the SNS™ Analog and Digital Clocks/Timers Installation Guide (SNSDOC-019).
Establish Connection
To begin updating the clock firmware using the SNS Configuration Tool, you must first establish a local network connection
between the clock and your computer. Your computer is required to have the SNS Configuration Tool installed. The SNS
Configuration Tool software is located on the SNS Resources CD. See the SNS Analog and Digital Clocks/Timers Installation
Guide for installation instructions.
