ICP DAS Co. Ltd. ZTM-WP User Manual

The ZTM-W / ZTM-P is a FCC certified design and a small-sized wireless-UART converter solution 

consisting of a micro controller unit with RF transceiver and a RF power amplifier front-end, or often 
called the low-noise amplifier (LNA), and it offers excellent the sensitivity. The ZTM-W / ZTM-P is 
based on the 2.4 GHz IEEE 802.15.4 standard, and either the function of radio-frequency or ZigBee 
firmware is available to be used. It can be controlled through an external host/system microcontroller 
or external evaluation software through the UART interface. We use the same hardware but the 
different firmware to achieve the RF Modem, ZigBee Coordinator or ZigBee Router. 

       

ZTM-W / ZTM-P module is intended for OEM integrator. The module includes PA/LNA and the 

either PCB Antenna or Connector of Dipole Antenna. It depends on market positioning to install 
firmware.
