SensGuard TCP LR X2
Wireless Gateway & Data Collector
Description
The SensGuard TCP LR X2 is an industrial-grade wireless gateway and data collector designed to receive measurements from wireless SensGuard sensors and transmit them to the SensGuard cloud monitoring platform.
Equipped with a standard RJ-45 Ethernet port, the gateway integrates seamlessly into existing network infrastructures. It supports multiple power options, including a 5V DC external power adapter or micro-USB connection, eliminating the need for internal batteries.
The device features built-in non-volatile buffer memory to store sensor readings locally during network outages, automatically uploading all buffered data to the server once internet connectivity is restored.
Key Features
- Multi-Sensor Support: Collects data from up to 250 wireless sensors.
- Flexible Power Options: Powered via micro-USB or an external 5V DC power adapter.
- Battery-Free Operation: Designed for maintenance-free continuous operation without internal batteries.
- Local Buffer Memory: Prevents data loss by saving measurements locally during internet outages.
- Range Extension: Can be configured to operate in Repeater Mode to extend sensor wireless coverage.
- Secure Transmission: Fully encrypted data exchange using the AES-128 standard.
Typical Applications
- Commercial Refrigeration: Centralized gateway for tracking temperatures in supermarkets and retail stores.
- Cold Storage & Warehouses: Aggregating data from remote temperature and humidity sensors in large logistics facilities.
- HVAC Systems: Integrating duct and room sensor measurements into facility monitoring networks.
- Data Centers & Server Rooms: Reliable data collection from server rack climate sensors.
- Museums & Historical Archives: Centralized gateway for localized environmental microclimate tracking.
Operating Instructions
Device Installation & Setup
The gateway is pre-configured to communicate out-of-the-box with the SensGuard monitoring portal (my.sensguard.lv). By default, DHCP client mode is enabled to automatically retrieve network settings.
- Connect the gateway's RJ-45 Ethernet port to an active network switch or router using a standard patch cable.
- Power on the device using a 5V DC power adapter or micro-USB connection.
- Log into the SensGuard cloud portal (my.sensguard.lv), navigate to the Connection section, and follow the step-by-step Connection Wizard to register your hardware.
Note: If a static IP address or custom network configuration is required, connect the gateway to a PC via USB and use the SensMax USB Configurator utility. Download the configurator tool here: usbconfig.zip.
Repeater Mode Configuration
The gateway can function as a wireless repeater to extend the radio range between remote sensors and a primary gateway:
- Disconnect the Ethernet (RJ-45) cable.
- Power on the device using a 5V DC adapter or USB.
- Press and hold the diagnostic button on the enclosure for more than 10 seconds.
- During this process, two yellow LEDs will illuminate first. Keep holding the button until they turn off and a single red LED turns on, indicating that Repeater Mode is active.
Note: Repeater Mode configuration is saved in non-volatile memory and persists after rebooting or power cycling the device.
Deactivating Repeater Mode:
- Press and hold the diagnostic button for 1 second to return the device to standard Gateway Mode.
