SVR DUAL
™
User’s Manual
Welcome To Decatur Electronics, Inc.!
Thank you for choosing this Decatur Electronics product—the SVR Dual™ is a highly advanced, low prole, surface velocity radar (SVR) with a water level sensor. The SVR Dual™ is extremely valuable for measuring water surface velocity during high-velocity ows and ood conditions where using contact measurement instruments poses a risk to safety.
The SVR Dual™ provides simutaneous velocity and distance to water measurement and incorporates many leading features such as cosine error correction for the vertical and horizontal angle positions of the transmitter to the target. The SVR Dual™ also contains a congurable horizontal cosine adjustment that may be used when the angle of the SVR Dual™ is not parallel to the ow of the target.
If you are as pleased with its performance as we think you will be, ask your Decatur sales representative about other Decatur products including the Genesis™ line of radars, the Onsite™ line of speed trailers, dollies, pole signs and the Responder™ line of in-car video systems.
Try any one of our products and see if you don't agree that it is the best-in-class!

Indicates a warning message about safety
precautions. Please read it carefully.
Indicates a helpful tip or precaution to note.
1. Safety Information
All service needs should be referred back to the manufacturer.
WARNINGS
• Do not over voltage the radar - it can damage the unit!
• The SVR Dual™ is designed to operate o of standard +12 VDC (+9 VDC to +24 VDC) from the serial cable.

User’s Manual
WARNINGS
• Opening the SVR Dual™ automatically voids any warranty still in eect. There are no user serviceable parts inside.
• Do not expose the SVR Dual™ to excessive moisture. Never submerge the device. The unit is only water resistant providing the power/data cable is plugged in.
• Do not drop the SVR Dual™ on hard surfaces since damage could occur. Units damaged by dropping or abuse are not covered for warranty repair.
Violation of these guidelines may void the warranty.

3. Getting Started
3.1 Introduction
The SVR Dual™ is a low prole surface velocity radar specically designed to measure water velocity and distance and then export that information as RS232 data via the special serial cable. This allows the SVR Dual™ to be used for a wide range of water applications. The SVR Dual™ comes with software on a ash drive that allows the user to congure certain parameters of the SVR Dual™ for specic applications. Refer to Section 4 for conguration information.
3.2 SVR Dual™ Panel Connector The SVR Dual™ housing has an 8-pin panel connector which will receive a variety of cable options. The standard cable is the serial cable which comes supplied with the SVR Dual™. The 8-pin connector and it's pin out appears below.

3.3 Connecting the Standard Serial Cable
The SVR Dual™ operates o of +12VDC and comes with a cable that has two connectors. The circular connector plugs into the SVR Dual™ and the DB-9 serial connector (shown in Figure 3.2b) is used for powering and communicating with the SVR Dual™. When connecting the cable it is important to understand that unlike standard RS232 serial connectors that have no +12VDC provisions, the SVR Dual's™ serial connector has two pins dedicated to B+ and ground for the purpose of powering the unit. Figure 3.3 shows the pin arrangement.

RS232 / RS485
• The SVR Dual™ will come set to RS232 or RS485 from the factory. If the unit is set for RS485 mode, then pins 2&3 above will assume this operation. All other pins are unchanged.

3.4 Mounting Conguration
The SVR Dual™ comes equipped with four mounting holes on the reverse side (See Figure 3.4). Use these holes only to mount the SVR Dual™ .

.
The unit can be mounted in a variety of ways using a horizontal or vertical pipe. The mounting bracket can be attached to the top or the rear of the unit. The bracket of the unit is then attached to a pipe using high strength 1/2 inch wide stainless steel adjustable hoops.
3.5 Mounting Examples
The following examples show standard mounting and positioning of the SVR Dual™. It is important to make sure that the unit is parallel with the surface of the water. If need, a level can be placed on the unit to insure level. In the examples below, a standard pole is used.

4. Conguring the SVR Dual™
If you are needing to program the SVR Dual™ and it is not yet connected to a system that will provide the 12 VDC needed to power it then the S769-78614-0 programming cable may be needed. Refer to Section 14.2 for more information regarding the cable.
Before proceeding make sure your computer has Microsoft® Net Framework Version 4.0™ installed. If not, you can install it by going to:
http://msdn.microsoft.com/en-us/netframework/aa569263.aspx.
4.1 Equipment Needed
• SVR Dual™ radar device
• SVR Dual™ serial or programming cable
• PC with either a usable RS232 serial port or a USB-to-RS232 adapter.
• Conguration Program from ash drive
• 12V power supply
4.2 Setup
1. Connect the SVR Dual™ to the programming cable using the end of the cable that has the red and black wire coming out of it.
SVR DUAL
™
User’s Manual
2. Connect the red wire to the positive (+12 VDC) of the power supply and connect the black wire to the negative (ground) side of the power supply. Do not turn the power supply on.
3. Connect the other end of the programming cable to the serial port of your computer. If you do not have a serial port and are using a USB to Serial adapter make sure you have installed the USB to serial adapter software (driver) rst. Then connect the adapter to the programming cable. Plug the USB to serial adapter into your computer's USB port.
4.3 Conguration Program Screen
1. Open and run the Conguration program; which is shown in Figure 4.3a.

2. The SVR Dual™ Conguration Program is designed to automatically recognize the assigned USB port. However, if for some reason it does not recognize the port you can nd what port has been assigned by checking "Device Manager/ Ports" on your computer. The port assignment will appear as "USB Serial Port". Note the port assignment. The example in Figure 4.3b shows that Port 4 has been assigned. Your port assignment may be dierent and the port assignment can change the next time the USB to Serial adapter is plugged in to the computer.

Device Manager screen
3. From the Conguration Program/Com Serial Port Settings screen (Figure 4.3c) click on the down arrow and select the COM port that your PC has assigned. If you are connecting through the computer's serial port, it will normally be "Com 1" or "Com 2". If you are using the USB to Serial adapter, use the port shown in Device Manager/Ports. Once the correct port is known, the Device Manager/Computer Management screens can be closed.
