® radar gun contains an antenna and transceiver for transmitting and receiving K-band frequencies. The exclusive Digital Signal Processing (DSP) algorithms in the Railmaster-VP use these frequencies to obtain target vehicle speeds, which appear in the display window. About This Manual Note the following symbols in this manual.
After you insert the batteries, press the POWER button. The Railmaster-VP will run a display test, show the results (8.8.8), flash the backlight in the speed display window, then the display will blank.
The locked speed flashes until you pull the trigger to clear the display. 1.1.4 Measuring a Target Speed Aim the Railmaster-VP at a moving target, then pull the trigger. The Railmaster-VP transmits a signal, then you will see the speed of the vehicle in the display window that is returning the strongest signal.
RAILMASTER-VP™ USER’S MANUAL 2. Components 2.1 Batteries ® The Railmaster-VP comes with a Black & Decker interchangeable battery system: two nickel-cadmium (NiCd), silver label, 3.6-volt VersaPak batteries and a two-port AC auto charger (part number P702-VP135). For increased runtime, you can use nickel metal hydride (NiMH), gold label, VersaPak batteries.
• Do not incinerate the batteries. They can explode. If you have problems or questions about your batteries, contact Decatur Electronics, 800.428.4315, Black & Decker ® at 800.54.HOWTO. 2.1.1 Removing Batteries...
RAILMASTER-VP™ USER’S MANUAL 2.2 Controls The faceplate control panel consists of three buttons MODE, SELECT, and POWER for navigating in two menus, the primary and secondary. Figure 2.2 The control panel 2.2.1 Mode and Select The MODE and SELECT buttons let you select options in a primary and secondary menu.
1/2 second. The locked speed flashes until you pull the trigger to clear the display. 2.5 Mounting Configurations The Railmaster-VP is compatible with large display signs, which display vehicle target speeds. Also, you can mount it to a standard tripod. To order tripods, see...
RAILMASTER-VP™ USER’S MANUAL 3. Operating Modes The control panel on the Railmaster-VP has two menus, the primary and secondary. The primary menu is the main operating mode, which you will work in most of the time. The secondary menu is for adjusting settings to save as a new default.
2: Whole Display 3 -> 320 5 -> 500 3 -> 275 3.2.2 Speed Units (Su) The Railmaster-VP records speeds in mph or kph. Select the speed units (Su). The options are 0, 1, or 5, which represent 0: MPH 1: KPH 5: KNOTS 3.2.3 Serial Output Mode (Prt)
To connect to a PC, plug a Decatur Electronics custom RS232 communications cable (part number S769-100) into the device and the serial communications port on your PC. (You can purchase this cable from Decatur Electronics, see section 12 How to Order Additional Products.)
RAILMASTER-VP™ USER’S MANUAL 5. Performance Tips Understanding potential radar interference and what to do when it occurs can greatly increase the radar’s performance. 5.1 How Radar Works Determining a vehicle’s speed, begins with the radar antenna transmitting and directing a beam of microwave energy (radio waves) at an approaching (or departing) target vehicle.
RAILMASTER-VP™ USER’S MANUAL 5.2.1 Angular Interference (Cosine Error Effect) The cosine effect causes the system to display a speed, which is lower than the actual vehicle speed. This condition exists when the target vehicle’s path is not parallel to the antenna, including conditions such as the vehicle traveling on a curve or a hill.
RAILMASTER-VP™ USER’S MANUAL 5.2.4 Large Objects The Railmaster-VP detects a wide range of objects. When an object is large, it is easy for the system to “see” it as the target. However, when a large target, such as a moving train, is not present, the Railmaster-VP will “see”...
RFI condition no longer exists. At that time, any locked speeds will display again. 5.2.7 Scanning The Railmaster-VP is designed to use while attached to a solid mount or hand-held in a steady position. Moving or “scanning” the antenna past stationary objects can cause the system to detect motion.
In addition to the system test, you can verify signal processing accuracy by using a tuning fork, which comes with the Railmaster-VP. To begin the test, tap the tines of the fork on a surface that is firm and non-metal. The tuning fork will ring audibly.
