Description

The DTD’s relay and open collector outputs can be programmed to close for the duration of tone, pulse immediately after completion of detection, wait a programmed (up to 9.99 seconds) length of time after detection, or latch/unlatch. Programming is performed using a non-dedicated PC’s USB port equipped with a serial terminal program like HyperTerminal, Tera Term, or PuTTY.
