TAPCO Radio 148221 900MHz Transceiver User Guide

Changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment.

Note: This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment.

RADIO 148221 TRANSCEIVER

The compact Radio 148221 900MHz transceiver replaces miles of cable in harsh industrial environments. Using fieldproven FHSS technology, which needs no additional FCC licensing in the Americas, OEMs can easily make existing systems wireless with little or no RF expertise.

OVERVIEW

The Radio 148221 is a cost effective, high performance, frequency hopping spread spectrum (FHSS) transceiver designed for integration into OEM systems operating under FCC part 15.247 regulations for the 900 MHz ISM band.

Radio 148221 transceivers operate in a Masterless architecture. The Radio 148221 instead uses a Timekeeper to synchronize the network. The Timekeeper can be selected manually or the network can use built in a.i. to pick a timekeeper. Timekeeper can act as a pseudo gateway in order to synchronize signals or devices can communicate directly to one another when synchronization is not necessary.

All Timekeeper devices broadcast an RF sync pulse on periodic intervals along with timing information for secondary io beacons that are pulsed on a digital output line.

Serial data will be routed according to the destination serial number.
Digital input signals will be broadcast and then synchronized on the timekeeper pulses.

To boost data integrity and security, the Radio 148221 uses FHSS technology with data whitening and 16bit CRC data integrity checks. Configuration data is stored in an on-board EEPROM.

All frequency hopping, synchronization, and RF system data transmission/reception is programmed in the factory and is performed by the transceiver, transparent to the OEM host.

The manufacturer is responsible for ensuring the final product meets all appropriate regulatory agency requirements listed herein before shipping any product.

Note: Unless mentioned specifically by name, the Radio 148221 modules are referred to as the radio or transceiver. Individual naming is used to differentiate product-specific features.

The host (any device to which the Radio 148221 is connected, such as a PC) are referred to as  OEM host.

This device complies with Industry Canada license-exempt RSS standard(s).
Operation is subject to the following two conditions:

1. This device may not cause interference, and (2) this device must accept any interference, including interference that may cause undesired operation of the device.

HOOKUP AND LAYOUT

Din1 is a Schmitt Trigger Input with min active Low voltage 0.7V and Active High voltage 2.5V.
Dout1/2 are push pull outputs.
RSSI uses 8bit 1 start 1 stop bit active low 460,800baud to transmit RSSI information in ascii format.
TermTxRx uses 8bit 1 start 1 stop bit active low 19,200baud to transmit and receive serial data over the air.
TermTx is in reference to the Host TX and TermRx is in reference to Host Rx.

HOST LAYOUT

TAPCO suggested Host layout using Samtec SMM-116-02-S-S
*Host layout may use any 2mm pitch connector suitable for mating with Samtec TMM-116-01-S-S-SM.

Frequency Hopping Spread Spectrum

A FHSS radio does just what its name implies – that is, it ‘hops’ from frequency to frequency over a wide band. The specific order in which frequencies are occupied is fixed but in a pseudo random order.

Modes of Operation

The Radio 148221 has 4 operating functions:

• Transmit serial data
• Receive serial data
• Hardware IO control
• Hardware Beacon outputs

Hardware IO mode acts like a one to many remote controls so when Digital input one on any device is activated, the radio broadcasts this information to all other radios on a synchronized beacon. When a remote device receives information that one of the other radios Digital Input 1 has been activated, it activates its Digital Output 1.

Hardware Beacon outputs are configurable at the factory to output a beacon pulse on Digital Output 2 in any 1 second period increment. The Fundamental System Timekeeper generates the timing for this pulse and keeps Listener radios updated as to the status of this Hardware Beacon Pulse.

Serial Data Received on any radio will be directed to the remote radio device that is getting addressed by the host application.
Local Serial Data received for device configuration will not be transmitted on the RF network.

Transmit Mode

All packets sent over the air are either Addressed or Broadcast packets. Broadcast and Addressed delivery can be controlled dynamically with the API Control byte. Contact the factory for details.

When a radio has data to transmit, it sends it out on its reserved timeslot. The number of devices on a network is configurable at the factory.

To increase the odds of successful delivery the host application is required to Transmit Retries.
RF Serial Communication is not transparent to the OEM host and the Manufacturer will need to advise the Host on how to apply data packaging for transmission OTA (over the air). Contact the factory for details.

Receive Mode

Serial data can be asynchronously received by Radio 148221 OTA then directed to the Host serial port.

RSSI – Received Signal Strength

RSSI is in units of dBm and is available through serial communication. Contact the factory for details on reading this information from the transceiver.

System Timing and Latency

Latency is the amount of time that it takes for an action to take place. There are different actions available in TapNet including remote digital control and serial data transmission/reception. IO latency is dependent on the size of the RF network.

7 Device networks require a maximum of 62.5ms for one transceiver to transmit information to the system and in as little as 9ms to transmit information directly.

16 Device networks require a maximum of 143ms for one transceiver to transmit information to the system and in as little as 9ms to transmit information directly.

System Throughput

Maximum System Throughput

• Timekeeper to Listener = 1280 baud continuous max host throughput rate
• Listener to Listener in direct mode = 1280 baud continuous max rate
• Listener to Listener in sync mode = 640 bytes baud continuous
• Maximum host serial payload size is 64 bytes.
• RF Data Rate default is 123kBaud.
  Other data rates and payload sizes are available. Contact TAPCO for details on custom serial data configurations.

System Operation

The Radio 148221 network is preconfigured at the factory so all the user needs to do is power up the devices and they will automatically sync and begin working. IO and OTA serial functionality is only available once a device is sync’d.

A flashing green LED indicates the TimeKeeper device. The Green LED specifically indicates that data has been transmitted OTA.

A red flashing LED indicates that a Listener Device is in sync with the TimeKeeper. The Red LED specifically indicates that RF data has been received OTA.
