Leonard Valve ProtoCessor Start-up Guide
Quick Start Guide
1. Record the information about the unit. (Section 3.1)
2. Set the COM settings for the device connected to ProtoCessor. (Section 3.3)
3. Connect ProtoCessor FPC-ED2’s 3 pin RS-485 port to the Field Protocol cabling. (Section 4.2)
4. Use a browser to access the ProtoCessor’s embedded tool, which is referred to in this manual as
the Web Configurator, to select the device that will be attached to ProtoCessor. Once the device
is selected, the ProtoCessor Automatically builds and loads the Configuration. (Section 5)
5. BACnet/IP, Modbus TCP/IP or EtherNet/IP: Use a browser to access the ProtoCessor Web
Configurator to change the IP Address. No changes to the configuration are necessary. (Section
5.5)

2 INTRODUCTION
2.1 ProtoCessor Gateway
The ProtoCessor is an embedded module that is designed into Leonard Valve’s product (hereafter called
“device”) and is preconfigured to support BACnet MS/TP, BACnet/IP, Metasys
®
N2 by JCI, Modbus
TCP/IP, Modbus RTU or EtherNet/IP.
It is not necessary to download any configuration files to support the required applications. The
ProtoCessor is pre-loaded with all the tested Profiles/Configurations for the device to support the desired
protocols.
Metasys is a registered trademark of Johnson Controls Inc.

3 SETUP FOR PROTOCESSOR
3.1 Record Identification Data
Each ProtoCessor has a unique part number located on the side or the back of the unit. This
number should be recorded, as it may be required for technical support. The numbers are as
follows:
Figure 1: ProtoCessor Part Numbers
• FPC-ED2 units have the following 2 ports: RS-485 + Ethernet
3.2 Point Count Capacity and Registers per Device
The total number of Registers presented by the device attached to the ProtoCessor cannot
exceed:
Figure 2: Supported Point Count Capacity
Figure 3: Registers per Device
3.3 Configuring Device Communications
3.3.1 Input COM Settings on the Device Connected to the ProtoCessor
• The connected serial device MUST have the same Baud Rate, Data Bits, Stop Bits, and
Parity settings as the ProtoCessor.
• Figure 4 specifies the device serial port settings required to communicate with the ProtoCessor.

4.2 BACnet MS/TP, Modbus RTU, Metasys N2: Wiring Field Port to RS-485
Network
• Connect the BACnet MS/TP, Modbus RTU or Metasys N2 RS-485 network wires to the 3-pin RS-
485 connector on ProtoCessor ED2 as shown below in Figure 6.
o Use standard grounding principles for RS-485 GND
• See Section 5.5 for information on connecting to BACnet/IP and Modbus TCP/IP
network.
• If the ProtoCessor is the last device on the BACnet MS/TP, Modbus RTU or Metasys N2
trunk, then the End-Of-Line Termination Switch needs to be enabled (Figure 7).
o The default setting from the factory is OFF (switch position = right side)
o To enable the EOL Termination, turn the EOL switch ON (switch position = left
side)
