Ports and Connections All connections and ports are located on the bottom of the unit, as shown in Figure 2-1. Table 2-1 provides additional information about each port/connection. Mounting hole Power/data port Figure 2-1: A101 ports and connectors Table 2-1: A101 ports and connections LED Display The A101 uses a single LED (see Figure 2-1) that provides system information based on the color and pulse of the LED as follows: • Red LED = power on • Amber LED = GPS lock • Green LED = DGPS position A101 Smart Antenna User Guide 6 PN 875-0324-000 Rev B1

Communication The A101 supports radar-simulated pulse output and various NMEA 2000 messages. Radar-Simulated Pulse Output The radar-simulated pulse output provides accurate ground speed. The A101 uses pin 12 for the speed out pin. Pin 12 will output a square wave with a 50% duty cycle and the frequency of the square wave varies directly with speed. 94 Hz represents a speed of 1 m/sec (or 28.65 pulse/foot traveled). Note: Pin 12 does not have any form of isolation or surge protection. Hemisphere GPS strongly recommends that you incorporate some form of isolation circuitry into your...

Mounting the A101 This section provides information on where to mount your antenna and the different mounting options available. Selecting the Proper Antenna Location Proper antenna placement is critical to positioning accuracy. To select the proper antenna location: * Place the antenna with an unobstructed view of the sky. An obstructed view of the sky may impair system performance. The GPS engine computes a position based on measurements from each satellite to the internal GPS receiver. * Mount the antenna on, or as close as possible to, the center of your point of measurement. For...

Magnetic Mount The magnetic mount can be screwed into the bottom of the A101 and mounts to metal surfaces. A metal disc and foam adhesive are included with each magnetic mount. Use the foam adhesive to bond the metal disc to the desired mounting location if there are no metal surfaces. To mount the A101 using the magnetic mount: 1. Clean and dry the surface where you will attach the metal disc. Remove the backing from one side of the foam adhesive and press the adhesive onto the mounting surface. Remove the backing from the other side of the foam adhesive and press the metal disc onto the...

Powering the A101 Power Considerations The A101 accepts an input voltage of 7-32 VDC. For best performance use a clean and continuous power supply. See Table B-4 on page 21 for complete power specifications. Connecting to a Power Source The A101 uses a single cable for power and data input/output. Note: A power/data cable is not supplied with the A101 but is available as an accessory item. See Table 1-1 on page 3 for a list of accessory items. The following information refers to using the accessory item cables available from Hemisphere GPS. The antenna end of the cable is terminated with an...
