Hardware; Ips2 24 Vdc Main Printed Circuit Board Rev. C - Protrol IPS2 24 VDC Manual

5 Hardware

The IPS2 unit is composed of two printed circuit boards (PCBs); one large circuit board forming the base and
a top circuit board that is located above of the other just beneath the front panel.
To access the reset button, firmware download port (C2 interface) and the internal serial port of IPS2, the
front cover must be removed. This is easily accomplished by removing the four screws in the corners of the
cover. Note that the screws need only to be turned 90 degrees.
