The new C2/TX Wireless Site Manager is the heart of third-generation wireless systems from GDS Corp. Designed to monitor from 1 to 32 wireless GASMAX TX gas detectors, the C2/TX incorporates the latest features while retaining the reliability and cost effectiveness of previous generation products.

The C2/TX WSM and GASMAX TX gas monitor have been designed from the ground up to deliver the best wireless solution for toxic and combustible gas detection available. Designed specifically for use with the new GASMAX TX gas monitor, the C2/TX controller features a high resolution LCD display and eight relays that can be programmed to signal multiple alarm levels, sensor fault, communications fault or low battery.

Digitally Connected, Wireless Enabled

Unlike mesh networks and other systems designed for short range applications, the C2/TX utilizes Frequency-Hopping Spread Spectrum (FHSS) modems that offer higher power, longer range and lower susceptibility to interference. An optional multi-interface board supports an RS-232 or RS-485 wired serial port for remote MODBUS access, a solid-state data logger with USB interface, a second 900 MHz or 2.4 GHz radio for dedicated wireless remote access as well as an 802.11 WiFi interface for access via smartphones or tablets. WiFi-enabled C2/ TX controllers also feature an integrated web server that allows users to remotely view real-time data, historical information and current configuration. With the correct password, remote users can change system setup variables. Finally, an optional satellite / cellular modem enables remote access from anywhere in North America.

Simplified Setup

Unlike previous generation products that required both the controller and gas detector be individually configured for gas type, engineering units, range and other parameters, the C2/TX automatically uploads the setup information from each GASMAX TX gas monitor. This reduces the possibility of errors and simplifies initial setup.


The C2/TX controller is designed for use in Class I Division 2 hazardous areas. An optional NEMA 7 enclosure allows use in Class I Div 1 areas. Up to 12 watts of 24 VDC power is available for auxiliary devices or transmitters. In addition, an auxiliary 50 watt DC supply is available.
