2.9.1.1. Remote Reset
A remote hardware reset of the cPCI-DMXS64GX is possible by sending a break on the
Serial Port 1 or Serial Port 2 (see section 3.1 for Remote Reset jumper setting). A break is
simple an abnormally long start bit (100ms or more) on the incoming data line. A break
signal is embedded in the data, so no special wire is required.
