P412 User’s Manual & Data Sheet Overview This document is the user’s manual and data sheet for the Time Domain PulsON 412 (“P412”) Ultra Wideband (UWB) ranging radio transceiver. The document is divided into the following sections.
P412 User’s Manual & Data Sheet Figure 1: Notional UWB pulse in both time and frequency domain. The P412 measures distance using a technique called Two Way Time of Flight. In this approach the radio requesting the range measurement (the Requestor) will transmit a packet of pulses that will be received by one or more units (the Responders). The responder will then measure the leading edge of the waveform relative to the radio lock spot and transmit this information in a return (or responding) packet.
P412 User’s Manual & Data Sheet 5 Additional information including all of the documents referenced in this section can be found on the web at www.timedomain.com. This includes: the API, software manuals, applications notes, white papers, examples, published papers, sample C code, sample Matlab, etc.

P412 User’s Manual & Data Sheet • 7 Wireless noise-like / covert data communications 3 Hardware Block Diagram This section provides and discusses at a high level the P412 functional hardware block diagram, as shown in Figure 4. Additional detail on the various interfaces is provided in Section 4. Fig. 4: P412 hardware functional block diagram To power the board, the user must supply a maximum of 3.8 Watts at any voltage between 5.75-30V.
P412 User’s Manual & Data Sheet The user can interface to the P412 through either USB (standard USB Micro B connector), Serial connection, or CAN. In addition, the user can request the P412 to report the board temperature. The physical interface to the P412 is through a pigtail (not provided). Provisions for soldering the pigtail to the board are provided. Each of the pigtail holes is also provided with a strain relief hole.
P412 User’s Manual & Data Sheet 4 Interfaces This section provides a detailed description of the various P412 interfaces. The overall board image in Figure 5 is referenced throughout this section. The user power, serial and CAN interfaces are all connected to the P412 via a soldered down pigtail (not provided). A set of strain relief holes is also providing. This allows the user to lace the pigtail wires through dedicated holes before soldering to the pad. This is detailed in Figure 6. USB 2.
P412 User’s Manual & Data Sheet 4.1 Indicator Lights The P412 is provided with two indicator LEDs mounted adjacent to the Digital Baseband FPGA. See Figure 5 for exact locations. The amber LED toggles at 1Hz to indicate that the FPGA has passed Built-In Test (BIT). If the FPGA fails BIT, then the amber LED will blink at approximately 10 Hz. The green LED is initially off indicating that the FPGA has not been loaded. It blinks rapidly to indicate that the FPGA has been loaded and is getting a clock.
P412 User’s Manual & Data Sheet 11 5 Mechanical Board outlines and mounting hole locations are indicated in Figure 7 and the hole dimensions are shown indexed in Figure 8. The nine mounting holes are sized for a #6 screw. It is anticipated that the number of mounting holes, size of the holes and placement separations are sufficient to satisfy most vibration requirements. All units are English/Imperial. Fig.
P412 User’s Manual & Data Sheet Fig. 8: Hole sizes: Index table The user must provide a sufficiently sized heat sink such that the temperatures of the board can be kept below the maximum allowable temperature for the target deployment environment. Most of the heat is generated by the AFE chip. There are two means by which this heat can be extracted from the board. First, a heat sink can be placed directly in contact with the AFE.

P412 User’s Manual & Data Sheet Topside View Back side clearance between boss landing and part is 22mil. Backside clearance between 262mil screw head and part is 41mil Topside clearance between boss and shield 40mil Part on backside All other boss clearances (top and back) are at least 50mil Fig. 11: Relevant clearances.
P412 User’s Manual & Data Sheet 6 Performance Specs Table 2 summarizes the P412 specifications and key performance parameters.
P412 User’s Manual & Data Sheet Dynamic Range: Integration: 1 (instantaneous) Integration: 16:1 (PII=4) Integration: 64:1 (PII=6) Integration: 1024:1 (PII=10) Integration: 32768:1 (PII=15) Pulse Repetition Rate (Nominal) RF Communications Channelization: Raw Data (Symbol) rates: Max Range (max FCC Part 15 transmit power, standard Broadspec Antennas, free space, thermally noise limited environment, clear line of sight) Comms type: Max user bytes/packet: Pulse integration rates (PII): Ranging Performance
P412 User’s Manual & Data Sheet constructed of wood frame and drywall (aka sheetrock or gypsum board), then one will experience a level of performance that is less than but close to LOS conditions. This is because wood and drywall do not significantly attenuate or disperse RF signals at the P412’s operating frequency. At the opposite end of the propagation spectrum would be operation inside a metal ship.
P412 User’s Manual & Data Sheet P400 Transmit Power (EIRP dBm) the P412 to a power meter. The maximum level shown in Figure 12 (-13 dBm at a gain setting of 63) corresponds to the maximum level permitted by FCC when used with the Broadspec antenna. It is not possible for the user to enter a value greater than 63. Using any antenna other than the Broadspec invalidates the certification.
P412 User’s Manual & Data Sheet Figure 13: Broadspec Antenna with right angle connector 8 FCC Compliance The P412 and associated Broadspec antenna have been designed to be in compliance with the Federal Communications Commission (FCC) regulations governing both UWB hand-held systems (Part 15.519) also known as “battery powered devices” and UWB Surveillance Systems (Part 15.511).
P412 User’s Manual & Data Sheet This label is located on the back or bottom side of the P412. See Figure 15. FCC ID Label Figure 15: Location of certification number 9 Export Restrictions Relating to export, the Department of Commerce’s Bureau of Industry and Security has assigned the Export Commodity Control Number (ECCN) of 5A001b.4 to the P412. Products falling under ECCN 5A001b.4 are controlled for export purposes pursuant to the Commerce Control List for National Security and Antiterrorism.
