UH9RX4000RF BASE

Figure 1 H-ITT RFbase H-ITT RFbase, model number 4000 instruction manual GENERAL: The RFbase communicates with all H-ITT RF clickers. The H-ITT acquisition program, version 1.9.1 or higher must be installed on your PC. There is no limit to the number of RF clickers (or RF links) that can be used with a single RFbase. The RFbase has 62 RF channels that can be selected, and has 4 selectable baud rates. The 62 RF channels are provided so that a classroom can have its unique RF channel so as not to interfere with adjacent classrooms, or other fixed frequency devices already installed in the classroom. INITIAL SET-UP: The unit provides both USB and Serial communications ports. Connect either of these ports to your classroom PC (do not connect both). The USB connection provides power to the unit, so this is the only connection needed. If the serial port is used, the unit must have an external power supply connected, use H-ITT part number #2003. On power up, the YELLOW indicator light will turn on and both the PC com and RF com indicators will blink 4 times. If the RF com indicator blinks more at a faster rate than the 4 initial blinks, this can indicate that the RF channel selected may have another fixed frequency transmitter operating on the same channel within the range of the base. If this occurs, it is recommended that a different channel be selected. Additionally, the RF channel should be selected based on a cooperative effort with nearby classrooms so that each classroom within about 500 feet operates the H-ITT CRS on a unique RF channel selection. CHANGING THE RF CHANNEL: The RFbase snap on cover must be removed to access the RF channel selector switch. To remove the cover, squeeze the bottom sides near the ends, and lift the top cover, it will un-snap. With the cover removed, Figure 1 shows the internal location of the 10- position DIP switch used for set up. Switch positions 1 through 6 set the RF channel. Table 1 shows the numeric value of the 62 selectable channels. In general, the 6 switches represent a 6 bit binary number. To decode this binary number, switch 1 is the LSB and switch 6 is the MSB. When the switch is ON the binary value is zero, and when the switch is OFF the binary value is one. The switch setting of 00 (all on) and 11 (all off) should not be used. In order for the student’s clickers to operate on the same RF channel as the RFbase, the selected RF channel must be published, or otherwise be made known to the students in the classroom where the H-ITT CRS is being used. A description of Student “log-in” for the classroom RF channel is provided in the clickers users guide and also in appendix A herein. 1 2 3 4 5 6 7 8 9 10 Switch positions 1 through 6 select the RF channel.

Reference figure 1 to locate the DIP switch, and table 2 for setting the desired baud rate. Table 2, SWITCH SETTINGS and resulting BAUD RATES. DIP SWITCH BAUD RATE 9 8 19.2K ON ON 38.4K ON OFF 57.6K OFF ON 115.2K OFF OFF OPERATING MODE: The RFbase has 2 operating modes: 1. Operating with H-ITT RF clickers. 2. Not used currently. DIP switch position10 is used to select the desired mode: ON is the RF clicker mode. The RFbase is factory set for operation with the H-ITT RF clickers. All above instructions apply when used for a H-ITT full RF based CRS. MOUNTING THE RFBASE. Before mounting the unit, connect the antenna to the screw on SMA connector on the end of the unit. The unit can be simply set on a table top, or mounted to a wall using the “key-hole” on the back of the unit to hang it. Position the antenna based on how the units is going to be mounted. Tests show the range is better when the unit is wall mounted with the antenna pointing up. For best performance: 1. The antenna should be vertical, or pointing up. 2. Avoid setting the unit on a metal table. 3. Mount the unit so it has a clear line-of-sight to the seats in the classroom. APPENDIX …

The analyzer was calibrated in dB above a microvolt at the output of the antenna. The resolution bandwidth was 100kHz with an appropriate sweep speed and the video bandwidth was 300kHz up to 1.0GHz and 1.0MHz with a video BW of 3.0MHz above 1.0GHz. When an emission was found, the table was rotated to produce the maximum signal strength. The antenna was placed in both the horizontal and vertical planes and the worse case emissions were reported. The spectrum was searched to at least the tenth (10) harmonic of the fundamental. Formula Of Conversion Factors: The Field Strength at 3m was established by adding the meter reading of the spectrum analyzer (which is set to read in units of dBuV) to the antenna correction factor supplied by the antenna manufacturer. The antenna correction factors are stated in terms of dB. The gain of the preselector was accounted for in the Spectrum Analyzer Meter Reading. Example: Freq (MHz) Meter Reading + ACF + CL = FS 33 20 dBuV + 10.36 dB + 0.5 = 30.86 dBuV/m @ 3m Power Line Conducted Interference: The procedure used was ANSI Standard C63.4-2003 using a 50uH LISN. Both lines were observed. The bandwidth of the spectrum analyzer was 10kHz with an appropriate sweep speed. The spectrum was scanned from 0.15 to 30 MHz. Occupied Bandwidth: A small sample of the transmitter output was fed into the spectrum analyzer and the attached plot was printed. The vertical sca…
