Introduction

Thank you for purchasing an RST-5003 Web Enabled Control Module from APG. We appreciate your
business! Please take a few minutes to familiarize yourself with your RST-5003 and this manual.

The RST-5003 Web Enabled Control Module oers a wide degree of integrated, exible, remote and local

control and monitoring for your system. The RST-5003 can control up to 10 APG Modbus sensors--any

combination of level, pressure, magnetostrictive and ultrasonic--along with one 4-20 mA sensor, and two

input or output relay terminals. All readings are available for control and monitoring via TCP/IP for local

or remote network access. The RST-5003 also had exible power options: it can use either POE or an
independent 12-28 VDC power source.

Reading your label

Every APG controller comes with a label that includes the controller’s model number, part number, and
serial number. The RST-5003 label also indicates the default IP address, subnet mask, and mac address.

Please ensure that the model number on your label matches your order.

Chapter 2: Installation and Removal Procedures and Notes

• Tools Needed

• You do not need any tools to install your RST-5003. Please consult each sensor’s user manual for any
sensor installation notes and instructions.

 NOTE: For any APG sensor user manual, please visit http://apgsensors.com/support.

• Connection Notes

• Up to 10 Modbus sensors can be connected to the RST-5003 in any combination.

• Only one 4-20 mA sensor can be connected to the RST-5003.

 IMPORTANT: Each Modbus sensor must be connected to the network individually and

assigned a unique Sensor Number before the next sensor can be added.

• Electrical Installation

• Connect any 4-20 mA sensor, relays, or switched inputs rst.

• Connect RST to Ethernet/network.

• Connect independant 12-28 VDC supply if not using POE.

• Connect and set up one Modbus sensor at a time.

 IMPORTANT: Multiple Modbus sensors added to the network simultaneously are all

assigned the same Modbus address/sensor number: 1. Sensors MUST be added to the
network individually.

• Software Setup

Initial setup of the RST-5003 and individual Modbus sensors is done via an embedded web server. The page
can be accessed by using either the serial number or local IP address of the RST-5003 and a web browser

(Internet Explorer, Chrome, Firefox, etc).

 NOTE: Port 6700 must be open on your local network for the RST-5003 to connect.

Accessing RST-5003 Embedded Web Server

The easier way to access the embedded web server is to type rst_xxx into a web browser on a computer
connected to the same local network as the RST-5003. xxx represents the numeric portion of the RST-5003’s
serial number. See Figures 2.1 and 2.2.

Figure 2.1

Figure 2.2

 NOTE: If your web browser performs a web search for “rst_xxx” istead of loading the

page, type “http://rst_xxx”.

Some networks will block this direct access to the RST-5003. If this is the case, you will need to use the IP ad­dress of your RST-5003 to access the embedded web server. The IP address can be obtained two ways: ask
your local network administrator, or logon to your APG-provided website, www.levelandow.com.

Tel: [phone] • Fax: [phone] • www.apgsensors.com • [e-mail]

After logging on to your APG-provided website, a list of sites will be displayed on your screen (see Figure

2.3). Select the site where the new RST-5003 is installed.

Figure 2.3

From the list of sensors at this site, select the sensor with the serial number that corresponds to the new
RST-5003. (See Figure 2.4.)

On the Sensor Information screen you will see

the IP Address of the newly installed RST-5003.

(See Figure 2.5.)

Type the RST’s IP address into your browser’s

address bar (See Figure 2.6).

Figure 2.5

 NOTE: For further information on using your APG-provided remote website, please

visit www.apgsensors.com/support for a user manual, or contact us at 1-888-525-7300.

Logging on to the RST-5003 Embedded Web Server

The RST’s embedded webpage should now be open, showing the Main Display page (See Figure 2.7). This
page lists the sensors attached to the RST-5003 and displays each sensor’s current reading. A 4-20 mA sen­sor will have “Analog Input” as its Sensor Number. The congured sensor number for each Modbus sensor

will show as its Sensor Number. Every new Modbus sensor defaults to sensor number 1.

Figure 2.7

 IMPORTANT: Multiple Modbus sensors added to the network simultaneously are all

assigned the same sensor number: 1. Sensors must be added to the network individually.
