Section 2 - Installation
Ethernet Cables
The PCC-IV can communicate with other Modbus devices via one or both Ethernet ports located on the CPU board.
This utilizes the Modbus TCP/IP communications protocol via a standard Ethernet (CAT5, CAT5e, CAT6, or similar)
cable. See Section 4 for more information.
Micro-USB Download Cable
The PCC/DCS-IV can upload and download blockware configurations and other diagnostic information via the front
or back micro-USB jack on the CPU board. The signals are standard USB 2.0 levels and can be directly connected
to a standard personal computer USB port. There is (1) USB port, but (2) physical USB jack locations. Jumpers on
the CPU board select the front or rear jack. The rear jack is used for PCC-IV applications, and the front jack is used
for DCS-IV applications. To make the front jack active, move both jumpers J2, to pins 1-3 & 2-4. To make the rear
jack active, move both jumpers J2, to pins 3-5 & 4-6.
