SiFLEX02 TRANSCEIVER MODULE MODULE USER’S GUIDE 2 Supporting Ping Pong Range Test on Host Board See the Development Kit User’s Guide for detailed information regarding Ping Pong Range Test usage. The Ping Pong Range Test firmware is built into the module firmware. This allows for the test to be used on the application host board. The following considerations need to be made in order to utilize the test. 2.1.1 Power A nominal 3.3 VDC power supply should be connected to the VCC - 3V3DC pin (26) on the module. Also, a ground connection on the GND pin (44) is required. If batteries are used be sure to install the jumper on J2 between pins 2-3. 2.1.2 LED’s Three LEDs should be connected to module pins 27-29. The cathode of each LED should be each pin. The anode of each LED should be connected to the 3.3 V power supply through a nominal resistor value in the range of 180 to 470 ohms. Module pin 27 should connect to a green LED, pin 28 should connect to a yellow LED, and pin 29 to a red LED. 2.1.3 Switches Module pin 31 should be connected to ground through a normally open tact switch. In addition a 10k ohm pull-up resistor to VCC should be connected to this pin as well. This switch is referred to as the USER1 button in the subsequent instructions. Also, the RESET pin should be connected to ground through a momentary contact normally open (NO) push button switch. This switch is referred to as the RESET button in the subsequent instructions.

SiFLEX02 TRANSCEIVER MODULE MODULE USER’S GUIDE 4 Wakeup/Reset Alerts See host message types 0x1C (Set Wakeup/Reset Settings) and 0x9E (Wakeup/Reset Alert Status) in the SiFLEX Host Protocol User’s Guide to use the features described below. 4.1 Wakeup Alert The Wakeup Alert Status message can be used to alert the host microcontroller when it wakes up from sleep. This useful for two main reasons: • The host microcontroller knows that the SiFLEX module is ready to operate and can then accept commands over the host interface. • The host microcontroller knows the SiFLEX module has woken up from sleep due to an errant condition. For example if noise appeared on the SiFLEX wakeup input pin and the host microcontroller did not know it was out of sleep and drawing current, the power budget could be exceeded. To wake the SiFLEX module out of sleep simply send a dummy byte to the module. The SiFLEX module will wake up from sleep in under 1mS, at which point the Wakeup Alert Status message will be sent to the host, if enabled. 4.2 Reset Alert The Reset Alert Status message can also be used to alert the host microcontroller when the module has been reset. This useful so the host microcontroller knows that the SiFLEX module is ready to operate and can then accept commands over the host interface.

SiFLEX02 TRANSCEIVER MODULE MODULE USER’S GUIDE 5.3 U.FL Connector and Helical Antenna 5.3.1 Module Footprint If using the U.FL connector with an external antenna, or the helical antenna, you do not need the extra provisions in the footprint for a wire or castellated antenna. Also you do not need to hang the module off the end of the carrier board or have a cut out in the carrier board. However if concerned with compatibility with other LSR ModFLEX modules see section 0 for more information.

SiFLEX02 TRANSCEIVER MODULE MODULE USER’S GUIDE 5.3.2 Removal of U.FL connector Care should be taken when mating or un-mating the U.FL plug from its receptacle as they are designed (by the manufacturer Hirose) for a maximum of 30 cycles (in practice probably anything more than five cycles is too much). The outer shell of the mating plug can bend or deform easily and not make good electrical contact, thus degrading RF performance - sometimes significantly. Figure 7 U.FL connector A special tool exists to safely remove the U.FL cable. One supplier of this tool is Hirose Electronics, their part number is U.FL-LP(V)-N-2. See picture below for what the tool looks like and how to use it. Figure 8 U.FL extraction tool The information in this document is subject to change without notice.

SiFLEX02 TRANSCEIVER MODULE MODULE USER’S GUIDE 5.4 Castellated Antenna The castellated antenna option allows the use of a RF connector or PCB trace antenna on the modules carrier board. This option is NOT included with the Module’s FCC/IC Certification. It will require an additional certification. LS Research is equipped with a certification lab and can assist in getting this done at a reasonable cost in a short period of time. The castellated antenna option is NOT available on all ModFLEX modules from LS Research. See section 5.6 for more information. Use of the castellated antenna will require the three pads shown in the figure below. If the castellated antenna option is not needed the pads may be eliminated from the footprint.

SiFLEX02 TRANSCEIVER MODULE MODULE USER’S GUIDE 5.5 Carrier Board Alignment Holes The ModFLEX modules have two 0.032” diameter non-plated holes in the PCB that can be used to align the module to the carrier board. When designing the carrier board it is recommended to include two matching alignment holes with copper pads surrounding the holes on the bottom side of the board. The purpose of the copper pads allows for soldering alignment pins when the carrier board is used as an alignment fixture, which is described in the following sections. Figure 12 Alignment holes on module and carrier board The information in this document is subject to change without notice.

SiFLEX02 TRANSCEIVER MODULE MODULE USER’S GUIDE 5.5.1 Constructing an alignment fixture Any carrier board can be made into an alignment fixture. When using the carrier board as an alignment fixture the alignment pins can be soldered to the bare carrier board to prevent them from falling out. Then by adding standoffs to the bare carrier board you have created an alignment fixture. Figure 13 Alignment fixture overview Step 1: Make an alignment fixture by soldering two Mill-Max 3120-2 series pins or equivalent into the PCB being used for the alignment fixture. For spacing, use 1/8” standoffs between this board and the target carrier board. Figure 14 Constructing an alignment fixture Step 2: Carefully place the target carrier board through the pins on the alignment fixture.
