NST-H Microprocessor Based Programmable Signal Transmitter

The NST-H is user configurable using our software on your PC/notebook . The easy to use software is available free from your supplier or can be downloaded from our web site and should be used in conjunction with the URC-1020 USB cable which incorporates an interface converter necessary for communications.The NST-H transmitter can be configured without any loop or power connected making it easy to configure in the workshop before installation.
