NOTE: RXT-300s will only communicate with other RXT-300s with the same network ID
and RF channel.
NOTE: Suggest using same Network ID as RF Channel which would allow for up to 16
systems (RF Channel / Network ID = 0-15). If configure two or more systems on same RF
Channel but different Network IDs that are nearby they will have to share that channel,
consequently it will take longer to poll and will cause data retransmits to occur.
Network Sleep
Sets the time in seconds that the network will sleep after polling all devices in the system
(Values: 0-1000). Used to extend battery life but also lengthens time between sensor
updates. Set to 0 to disable Network Sleep.
4.3.2 Zones
Zones section allows user to create more than one Alarm Zone. As each Zone is added the WCT will create a
default name. The user can change these to a more a meaningful name.
Zone Name
The user will enter Alarm Zone names here. Up to 16 Zones can be added.
4.4 RXT-300 Parameters Detailed
After setting up the system parameters, the user must identify and add the RXT-300 transceivers that will be
used in the system. Since this is the heart of each of the Station types there are several parameters that must be
set. These include Modbus™ settings and Alarm settings. The Alarm settings include RXT-300 Alarm event
mapping to Alarm Outputs, the Zone(s) that the RXT-300 will be placed in and the Alarm Output property
settings. Some of these are grouped and set within submenus on the WCT.
4.4.1 RXT-300 Main Settings
RXT Name Alphanumeric name for the RXT-300 in the system. Set to a meaningful name for the
user and the first several characters will appear on the HMI Panel display. Has no
operational significance.
Unique Device ID Precisely identifies the RXT-300 using the serial number that is stamped on the body of
the RXT-300 itself.
Modbus Address This is the Modbus™ address of the RXT-300 and is incremented to the next address
starting at 161 each time a RXT-300 is added. It is used such things as addressing
4-20mA sensors local to that RXT-300.
Priority Used in guiding the election of the Master RXT-300 and can have a value of 0-255.
Priority is incremented starting at 1 each time a RXT-300 is added. The RXT-300 with a
priority of 1 will be the first to be elected as a Master if is it is powered on and working
and a RXT-300 with priority of 255 would be the last one elected as Master. If two or
more RXT-300s have equal priority, the one with the lowest serial number will be
selected. If a priority of 0 is assigned to a RXT-300 it will never try to become Master of
the network.
Low Battery If a battery is attached the user will set the low battery threshold here. It is set in number
of Days / Hours / Minutes and represents the time remaining before the battery is depleted.
The user should set the threshold based upon when the battery can be replaced which
includes having a fully charged battery and how long it will take to get personnel out to
the site.
