Ver.1.0 1. Overview The FDP03TJ010/020 (hereinafter referred to as the "FDP03") is a 2.4GHz-band wireless radio modem with a compact and low power consumption design. FDP03TJ010 should be connected to an external antenna by an antenna connector. FDP03TJ020 equips built-in antenna Do NOT place FDP03TJ020 near any metal objects. Because FDP03TJ020 uses built-in antenna, RF radio will be blocked and will have unnecessary reflections if it is placed near metal objects.
Ver.1.0 At that time, the receiver FDP03 responds an acknowledgement “ACK” signal to the sender FDP03 for notifying data packet receiving if "Enabling destination address check at reception" function of the REG18 register is turned on.
Ver.1.0 After entering a command to the sender FDP03, do not input the next command until the P0 response for the entered command is returned. Sending a new command before the P0 response is received, it may cause of command error and/or unpredictable operation. When "Disabling response" function of REG13 register of the sender FDP03 is turned on, the next command should be input after waiting a time period of expected P0 response.
Ver.1.0 2.2 Headerless Packet Transmission Mode By setting "Headerless packet transmission mode" on the REG03 register of the FDP03, the FDP03 transmits packets by wireless transmission to a destination address that is defined by the REG02 register. At this mode, a header part (command header "@", command "TXT" or "TBN", destination address, and number of message bytes [for TBN command]) can be eliminated. The trigger of data transmission can be defined by the setting of REG24 register.
Ver.1.0 2.3 Serial-Output Data Format of Receiver Side at The Transmission Mode Data format of the receiver side that outputs to the serial port varies depending on the transmission mode (packet transmission or headerless packet transmission mode). The below table shows combination of the data format and the mode setting.
Ver.1.0 2.4 Broadcast Transmission Mode It is possible to send data by broadcast transmission. Broadcast transmission mode can be used by setting the destination address to “255” at packet transmission or headerless packet. In broadcast transmission mode, the sender FDP03 transmits data packet defined times by REG11 register + 1 time. If "Enabling response" function is turned on, the sender FDP03 sends response signal to the host. For more details, see the section 2.1.
Ver.1.0 3. Data Transfer 3.1. Data Transfer Mode FDP03 has 2 kinds of data transfer mode. One is “Interchange” mode that is possible to exchange data between other FDP series. Another is “Communication Distance Extend” mode. The initial setting is “Interchange” mode. The data transfer mode should be same setting among communication partners. If the mode is different each other, it is impossible to communicate with. 3.2. Setting 3.2.1.
Ver.1.0 4. Transmission Timing 4.1 Transmission Timing At packet transmission mode, the FDP03 can transmit up to 130 bytes of message as a single packet. However, the radio transmission unit of the data is divided by 26 bytes. Since the FDP03 internally divides a message by 26 bytes when the packet size is bigger than 26 bytes, total data transmission time is varies with the data size. . In headerless packet transmission mode, the FDP03 transmits each message in units of 26 bytes without dividing them.
Ver.1.0 ① Serial input of transmission data packet The time required to data input between the host1 and the sender FDP03 is defined by below communication parameter.
Ver.1.0 ⑧ ACK packet generation It is time for ACK packet generation. It takes 1.0 ms ⑨ ACK packet transmission It is time for ACK packet transmission that the acknowledgement of data packet reception. It takes 0.45 ms. ⑩ ACK reception processing It is processing time for ACK packet. It takes 1.0ms. ⑪ Serial output of received packet It is time for output of received data packet to the host 2 through the serial port. on the communication setting between the host 2 and the receiver FDP03.
Ver.1.0 Trigger of the data transmission is delimiter at headerless packet transmission mode: Trigger of the data transmission is time-out at headerless packet transmission mode 0 2 *1 If the setting value is less than 3ms, the value of “B” will be “3”. *2 At headerless packet mode, the value of C is always 1. The total time until completion of the data transmission is calculated by below formula. Bit length per byte Line speed of the sender × 1000 × (size of message in bytes + A + 4) + B + 6.4 × C + 1.
Ver.1.0 4.2 Time period of the case that data re-transmission of divided packet is occurred at packet transmission mode When packet data size is exceeding 26 bytes, it is divided into several packets that data size is 26 bytes. At that time, each divided packet is sent defined re-transmission times. Thus, maximum data transmission period will be (setting of REG11 register + 1) x 5 times. (REG11 register is a parameter of data re-transmission frequency.) It takes 7.
Ver.1.0 5. Low Power Stand-by Mode This mode realizes low power consumption drive by switching ON and Off of RF circuit. It is possible to set this low power stand-by mode by the memory register (REG21: bit 2) or the command. If this mode is set by the command, this mode is released by the main power OFF or by set to power down mode. 5.1. Operation Flow By repeating “stand-by mode” and “sleep mode”, the power consumption at the RF circuit is reduced.
Ver.1.0 5.2.2. Setting by the command It is also possible to set “Low Power Stand-by Mode” by below listed commands. For mode detail, please check “Commands” section below.
Ver.1.0 6. RF Circuit Power Control Mode This mode can realize low power consumption operation by stopping RF circuit. 6.1. Operation Flow It is possible to control ON/OFF of RF circuit by ROF/RON command. For more detail of ROF/RON command, please check “Commands” section below. Current Consumption ROF Command RON Command RF OFF ROF Command RF ON RF OFF Wireless communication is completely cut when RF circuit is OFF.
Ver.1.0 7. Power Down Mode If the voltage level of the /SHUT terminal is set to “Low” level, the power source of the FDP03 is cut and it becomes to “Power Down Mode”. During the “power Down Mode”, all functions of FDP03 does not work. When the voltage level of the /SHUT terminal is set to “High” level, the FRP02 is to be the operation mode.
