1.1. Introduction
This manual describes how to install the Raptor™ Protocol Converter and configure it to
communicate using the Modbus, BACnet, and SNMP protocols.
C HAPTER
CHAPTER 0PRODUCT OVERVIEW
IMPORTANT Basic configuration to install the hardware and connect the Protocol Converter to the network
is available from RLE. However, the Protocol Converter is an advanced product, and you must
have in-depth knowledge of the Modbus, BACnet, and SNMP protocols to complete the
configuration.
1.2. Product Description
TheProtocol Converter receives one or more protocol types and outputs up to three protocol
types. The Protocol Converter can receive data from slave devices using Modbus RTU,
Modbus TCP/IP, BACnet/IP, or SNMP (integer data). The Protocol Converter can then be
polled by a master unit via SNMP, Modbus RTU, Modbus TCP/IP, or BACnet/IP. In addition,
the Dual Port Protocol Converter can be configured as a slave (Note: only as a slave) and
polled by a master unit via BACnet MS/TP.
There are two versions of the Protocol Converter: the “standard” version, and the “dual port”
version, which contains two additional EIA-485 ports for expanded connectivity and
communication.

Data transmit/receive indicators (two on the left available with
Dual Port Protocol Converter only)
1.2.1 Rear Panel Indicators
The back of the Protocol Converter has the following indicators:
♦ Two indicators to show when data is being transmitted and received through the EIA-485
port (the Dual Port Protocol Converter contains three EIA-485 ports and three sets of
transmit-receive indicators). When data is either being transmitted or received, the status
lights will blink. If no information is being communicated, the lights are off.
♦ One status indicator to show when the Protocol Converter is booting up or has an alarm
condition. If neither of these is occurring, the light is off.

CHAPTER 0INSTALLATION
2.1. Register the Protocol Converter
Go to http://www.rletech.com/ and enter the requested information in the Product Registration
form. Submit the form to register your product.
C HAPTER
2.2. Mount the Protocol Converter
The Protocol Converter comes with mounting brackets to allow the unit to be installed in a
19-inch (0.48m) rack.
1 Using the screws provided, attach the mounting brackets to the sides of the device.
Figure 2.1
NOTE The brackets can be reversed so the other side of the Protocol Converter is facing outward.
2
Install the Protocol Converter in the rack.
3 Use the proper anchoring method to mount the Protocol Converter securely in the rack.

2 Installation
2.3. Wire the Protocol Converter
If you plan to use the EIA-485 port for Modbus RTU communication, RLE Technologies
recommends an 18 AWG shielded, twisted-pair stranded copper wire for the connection. RLE
recommends no more than 2,000 feet (609.6m) of wire at this specification. If longer runs are
needed, contact RLE Technologies for application guidance.
2.3.1 Power Supply & Ground Connections
To provide power and ground connections to the Protocol Converter:
1 Connect an 18 AWG ground wire from the ground terminal to a suitable earth ground.
2 Connect power to the Protocol Converter in one of two ways, as shown in Figure 2.2:
a Plug the wall adapter (provided) into the power jack on the Protocol Converter and into a
UPS outlet.
b Connect a dedicated 24VDC power supply to the + and - terminals to the left of the
power jack.
IMPORTANT RLE Technologies recommends powering the Protocol Converter from a UPS (uninterruptible
power supply) so the Protocol Converter can send alarm notifications during a power outage.

2.3.2 RJ45 Ethernet Connection
The Protocol Converter has an internal 10/100BaseT Ethernet port used to configure the
Protocol Converter. The Ethernet port supports Web browser access, BACnet, Modbus,
SNMP, and SMTP (email).
Direct Connection
To make a direct connection between the Protocol Converter and a computer or laptop using
the crossover cable - the blue cable with yellow connectors provided with the device.

2.3.4 Modbus EIA-485 Connections
The Protocol Converter can function as a Modbus Slave or Modbus Master over an EIA-485
hardware connection. The Dual Port Protocol Converter contains three EIA-485 ports, and
EIA-485 Port 2 can be configured as either a 2-wire or 4-wire connection by wiring the port
appropriately and turning on the Duplex DIP switch. See Table 1.2 and Table 1.3 on page 14
for information about configuring this port.

CHAPTER 0CONFIGURATION
The Protocol Converter allows you to view and configure slave devices and slave registers
over the Web. To access the Web interface, you must first set up the Protocol Converter to
communicate over the Internet. To set the IP address, see “Configure Communications” on
page 21.
Follow the order of the sections in this chapter to completely configure the slave devices,
registers, and the Protocol Converter.
3.1. Configure Communications
The Protocol Converter will not communicate over a user’s network the first time it is
connected to the network. At the factory, the Protocol Converter is set with a default IP
address of 10.0.0.188 and Subnet Mask: 255.255.255.0.
You must change this default address to an IP address that corresponds with your network
before the Protocol Converter can communicate over the network. Use one of these vehicles to
change the IP address:
♦ A Web browser
♦ The EIA-232 interface
