Output Pulse Definition - Advantech ADAM-5240 User Manual

2.3 Output Pulse Definition

The output pulse command of ADAM-5240 is from MCX314AS chip.
The pulse command has two types. One is in Up/Down mode and another
is in Pulse/Direction mode. While nP+P is differential from nP+N and
nP-P is differential from nP-N. After system reset, the nP+P and nP-P is
low level, and this invert output (nP+N, nP-N) is high level, and the
de-fault setting of pulse output mode is Up/Down. User can change the
output mode into Pulse/Direction mode by writing specified command
system register.

From the circuit shown above (Figure 3-3), the default output mode is dif-
ferential output. For single ended output use, user can change jumpers
JP1~8 to +5V. Note that you should prevent from the noise interference
when using jumpers JP1~8 to output internal +5V to external device.
