2.  General Information 
The EchoView Host Mini-Controller is the cornerstone of RAE Systems’ Closed-Loop Wireless 
Solutions for portable gas monitors. This rugged handheld device can establish a self-sufficient 
network with up to eight supported RAE Systems portable wireless monitors and display their 
readings and alarm status in real time on an easy-to-read screen, supplemented by audible and 
visible alerts. 
MeshGuard LEL IR single combustible-gas LEL (Lower Explosive Limit) monitor and the 
MeshGuard CO2 IR (CO
2
) monitor are integrated with a wireless mesh network-enabled 
transmission radio module. Each has the option of relaying the wireless signal to other MeshGuard 
LEL IRs or MeshGuard CO2 IRs as needed, to bypass obstacles.  The built-in radio board operates 
on a frequency of 2.4GHz and complies with IEEE 802.15.4 standard. Both MeshGuard 
instruments operate with the FMC-2000 wireless controller on a flexible, robust wireless network to 
provide reliable, low-cost operation. It also works in a ProRAE Guardian network with a PC, and it 
supports point-to-point and point-to-multi-point networks.
