Power Supply Options
The MDS-GP board provides four different power input options ( Figure 3
and Figure 4 ):
Connect only one power source at a time.
•
5 V DC into J14 — The 5 V power supply included with Zilog ®
MDS-PM development kits can be used for this input to power both
the MDS-GP board and the MDS processor module.
•
9 V to 12 V DC into J25 — The eZ80Acclaim! ® development kits ship
with a 9 V DC power supply.
•
12 V DC into RS-485 connector, J4 — This connector provides another
means for supplying power to the board (Battery holder BT1 must be
empty).
•
4 AA cells in battery holder BT1 — Switch S2 present on the top right-
hand corner of the board turns the battery power source ON or OFF.
Ensure S2 is OFF or remove the batteries before connecting
another power source.
1. Do not use the DC input jack on the MDS-PM board when it is
plugged into the MDS-GP board. You must power the system with one
of the MDS-GP power supply inputs.
2. If your application is using the on-board relays, then you must
provide 9 V to 12 V DC into the MDS-GP board or change out the
relays to 5 V parts.
