Overview

The MeshNet Wireless Dual Channel 4 Wire RTD Input Gen 2, MN-RTD4W-H, offers an innovative way to monitor up to two (2) 4-Wire RTD temperature probes. The RTD Input provides highly accurate and precise readings from the RTD probes. The product also contains a memory buffer capable of holding 2048 sensor readings, a high power radio with 10x the transmission range, RTD fault detection, and screw-down terminals. Together these features offer an efficient and flexible system for monitoring wide temperature ranges from -200 to 650°C (RTD dependent) the temperature at multiple indoor and outdoor locations.

Reliability

Our MeshNet Generation 2 sensor technology utilizes a multi-pronged approach to provide great reliability. It prevents data gaps and enables the Generation 2 MeshNet sensor to provide a complete log of your temperature data in spite of data interruptions such as; power outages, network failures, or other obstructions.

• Sensors send and receive data packets - Each sensor (node) has the capability to both transmit and receive data packets. The ability to receive confirmations enables the sensor to alter its behavior to address a failed transmission.
• Sensors buffer data - If a failed transmission occurs, the sensor immediately begins buffering critical sensor data within its internal memory. The buffer's capacity is sufficient to log temperature data for up to 21.3 days at a 15 minute logging rate.
• Sensors scan and hop frequencies - If a failed transmission occurs, sensors then search available channels for the MeshNet Controller. The MeshNet Controller will hop frequencies which allow the system to navigate to less trafficked bands as the radio environment changes.
• Sensors report transmission strength - All MeshNet devices report the strength of the transmissions they receive, allowing areas that may be susceptible to interference to be identified and addressed proactively (e.g. adding repeaters).

Wire Free Sensor Setup

The Gen 2 MeshNet Sensors feature the new Wireless Linking capability, which eliminates the need for a physical connection between the MeshNet Controller and the MeshNet Sensor during the initial setup. The Wireless Linking process allows the sensor and controller to exchange all necessary information for joining the unique Wireless network; and since each network has a unique identifier, multiple wireless networks can operate in the same vicinity. Sensors can switch networks through repeating the linking process with the new wireless network’s controller. The steps to the straightforward linking process are below:

1. Connect the MeshNet Controller to the network and power.
2. Locate the MeshNet controller on the network by either:
• Downloading and running EDS Scanner, or
• Checking the DHCP Server for the assigned IP Address.
3. From the MeshNet Controller's home page select "System Configuration>Devices" from the menu bar.  The device page enables you to link and unlink sensors from the MeshNet Controller.
4. You will be prompted for login credentials.  The defaults are User Name "admin" and Password "eds".  
5. Insert batteries into the sensor.  The sensor will appear in the "Unlinked Devices" section.
6. Select the sensor when it appears and then click "OK" on the pop-up prompt.

The sensor will be linked (and moved to the "Linked Devices" section) on its next transmission.
