Chapter 4 Interface Circuits
4.1 Pulse and Direction Signals PUL/DIR
The DMC5400 can output 4 axes PUL/DIR signals to control 4 stepping/digital servo motor drivers. For every
axis, two pairs of PUL and DIR signals are used to send the pulse train and to indicate the direction. The PUL and
DIR signals can also be programmed as CW and CCW signals pair, see
“
Software Manual for the DMC5400

”
for more information. The interface circuit of the PUL and DIR signals is shown as figure 4.1.
Each signal consists of a pair of differential signals. For example, the PUL0 is consisted of PUL0+ and PUL0-
signals. The following table shows all the PUL/DIR output signals on X1 and X2 connectors.

There are 8 jumpers (J1~J8) on the DMC5400 which can be used to set PUL/DIR command signals to either
single-ended (open collector) or differential. The default settings are the single-ended modes (J1~J8 are short
circuit between pin2 and pin3.). Differential signals are preferred due to their excellent noise immunity.
Recommend use differential output if possible. See page6 of this manual.
