3.6.1 MPG Encoder Input Connection
In PCI-1241/1242, we provide 5 encoder input channels. Four encoder
input channels are for the MOTOR DRIVER connection, and the 5th
encoder input channel is specially designed for the manual pulse genera-
tor (MPG) device connector. There is an on-board 10-pin simple horn
male connector (J3) on PCI-1241/1242. For PCI-1241/1242, we offer
accessories such as a conversion bracket with flat cable. One side of the
flat cable is a 10-pin simple horn female connector for connecting to the
J3 on PCI-1241/1242. The other end of the flat cable is a DB-9 male con-
nector for connecting to external MPG devices. Figure 3-13 shows the pin
assignment of the DB-9 male connector on the conversion bracket and
Figure 3-14 shows its wiring diagram.
Pin 9 MPG_VCC is a power pin that provides +5V or +12V power output
selected by jumper JP1 and has a fuse protected design.
Fuse specifications:
· 0.5A Normal, Imax: 40A, Vmax: 13V
· Time-to-Trip: 0.002sec@40A, 100sec@1A
