1. Overview

Overview

1.1.

OverviewOverview

The AC4424 is a member of AeroComm’s ConnexRF OEM transceiver family. It is designed for integration into OEM systems operating under FCC part 15.247 regulations for the 2.4 GHz ISM band.

The AC4424 is a cost-effective, high performance, 2.4 GHz frequency hopping spread spectrum transceiver. It provides an asynchronous TTL level serial interface for OEM Host communications. Communications include both system and configuration data. The Host supplies system data for transmission to other Host(s). Configuration data is stored in an onboard EEPROM. All frequency hopping, synchronization, and RF system data transmission/reception is performed by the transceiver.

The AC4424 transceivers can be used as a direct serial cable replacement – requiring no special Host software for operation. They also feature a number of On-the-Fly Control Commands providing the OEM Host with a very versatile interface for any situation.

AC4424 transceivers operate in a Point-to-Point or Point-to-Multipoint, Client-Server or Peerto-Peer architecture. One transceiver is configured as a Server and there can be one or many Clients. To establish synchronization between transceivers, the Server emits a beacon. Upon detecting a beacon, a Client transceiver informs its Host and a RF link is established.

There are two data rates the OEM should be aware of:

• Serial Interface Data Rate – All transceivers can be configured to common PC serial port baud rates from 110 bps to 288,000 bps.

• Effective Data Transmission Rate – The AC4424 is a highly efficient, low-latency transceiver. The RF baud rate of the AC4424 is fixed at 576kbps and is independent of the serial interface data rate.

This document contains information about the hardware and software interface between an AeroComm AC4424 transceiver and an OEM Host. Information includes the theory of operation, specifications, interface definition, configuration information and mechanical drawing.

AC4424 AT COMMANDS

4.44.4

AC4424 AT CAC4424 AT C

The AT Command mode implemented in the AC4424 creates a virtual version of the Command/Data pin. The “Enter AT Command Mode” Command asserts this virtual pin Low (to signify Command Mode) and the “Exit AT Command Mode” Command asserts this virtual pin High (to signify Data). Once this pin has been asserted Low, all On-the-Fly CC Commands documented in the manual are supported.

When in AT Command Mode, the user cannot send or receive RF packets. However, an ambiguity of approximately 10ms exists where, if the “Enter AT Command Mode” command has been sent to the transceiver at the same time an RF packet is being received, the RF packet could be sent to the OEM Host before the “Enter AT Command Mode” command response is sent to the OEM Host.

NOTE: The RF packet size must be set to a minimum of 6 bytes in order to enter Command

Prior to sending the “Enter AT Command Mode” command to the transceiver, the OEM Host must ensure that the RF transmit buffer of the transceiver is empty (if the buffer is not empty, the ”Enter AT Command Mode” command will be interpreted as packet data and will be transmitted out over the RF). This can be accomplished by waiting up to one second between the last transmit packet and the AT Command. The OEM Host must also ensure that the RF Packe

The AC4424 transceiver contains static memory that holds many of the parameters that control the transceiver operation. Using the “CC” command set allows many of these parameters to be changed during system operation. Because the memory these commands affect is static, when the transceiver is reset, these parameters will revert back to the settings stored in the EEPROM.

While in CC Command mode using pin 17 (Command/Data), the RF interface of the transceiver is still active. Therefore, it can receive packets from remote transceivers while in CC Command mode and forward these to the OEM Host. While in CC Command mode using AT Commands, the RF interface of the transceiver is active, but packets sent from other transceivers will not be received. The transceiver uses Interface Timeout/RF Packet Size determine when a CC Command is complete. Therefore, there should be no delay between each character as it is sent from the OEM Host to the transceiver or the transceiver will not recognize the command. If the OEM Host has sent a CC Command to the transceiver and an RF packet is received by the transceiver, the transceiver will send the CC Command response to the OEM Host before sending the packet. However, if an RF packet is received before the Interface Timeout expires on a CC Command, the transceiver will send the packet to the OEM Host before sending the CC Command response.

When an invalid command is sent, the radio scans the command to see if it has a valid command followed by bytes not associated with the command, in which case the radio discards the invalid bytes and accepts the command. In all other cases, the radio returns the first byte of the invalid command back to the user and discards the rest.

4.5.54.5.5

After the Host issues the power-down command to the transceiver, the transceiver will deassert the In_Range line after entering power-down. A Client transceiver in power-down will remain in sync with a Server for a minimum of 2 minutes. To maintain synchronization with the Server, this Client transceiver should re-sync to the Server at least once every 2 minutes. This re-sync is accomplished by issuing the Power the In Range line to go active. Once this occurs, the Client transceiver is in sync with the Server and can be put back into power-down.

The AC4424 accepts 5V TTL level asynchronous serial data in the RXD pin and interprets that data as either Command Data or Transmit Data. Data is sent from the transceiver to the OEM Host via the TXD pin. The data must be of the format 8-N-1 (8 data bits, No Parity bits, One stop bit).

5.1.2 Hop Frame (pin 6)

5.1.25.1.2

The AC4424 is a frequency hopping spread spectrum radio. Frequency hopping allows the system to hop around interference in order to provide a better wireless link. Hop Frame transitions logic Low at the start of a hop and transitions logic High at the completion of a hop. The OEM Host is not required to monitor Hop Frame.

5.1.35.1.3

The AC4424 has an interface buffer size of 256 bytes. If the buffer fills up and more bytes are sent to the transceiver before the buffer can be emptied, data corruption will occur. The transceiver prevents this corruption by asserting CTS High as the buffer fills up and taking CTS Low as the buffer is emptied. CTS On operation of CTS. CTS On specifies the amount of bytes that must be in the buffer for CTS to be disabled (High). Even while CTS is disabled, the OEM Host can still send data to the transceiver, but it should do so carefully. Once CTS is disabled, it will remain disabled until the buffer is reduced to the size specified by CTS On Hysteresis. The following equation should always be used for setting CTS On, CTS On Hysteresis and RF Packet Size

In Addressed Acknowledge Mode, the RF packet is sent out to the receiver designated by the Destination Address

Destination AddressDestination Address the intended receiver. Transparent to the OEM Host, the sending transceiver will send the RF packet to the intended receiver. If the receiver receives the packet free of errors, it will tell the sender. If the sender does not receive this acknowledge, it will assume the packet was never received and retry the packet. This will go on until the packet is successfully received or the transmitter exhausts all of its retries. The received packet will only be sent to the OEM Host if and when it is received free of errors.

In Broadcast Acknowledge Mode, the RF packet is broadcast out to all eligible receivers on the network. In order to increase the odds of successful delivery, Broadcast Attempts used to increase the odds of successful delivery to the intended receiver(s). Transparent to the OEM Host, the sending transceiver will send the RF packet to the intended receiver. If the receiver detects a packet error, it will throw out the packet. This will go on until the packet is successfully received or the transmitter exhausts all of its attempts. Once the receiver successfully receives the packet it will send the packet to the OEM Host. It will throw out any duplicates caused by further Broadcast Attempts. The received packet will only be sent to the OEM Host if it is received free of errors.

5.2.3 Random Back Off

5.2.35.2.3

Random Back Off

Random Back Off – If multiple AC4424 transceivers try to send packets out over the RF at

Random Back Off Random Back Off the exact same time, the packets will collide and will not be received by the intended receiver. In fact, if after a collision occurs, both transceivers retry at the same time, the retry will also fail. To avoid further collisions, a transceiver can be programmed to wait a random number of packet times (hops) before resending its data. The amount of randomness is controlled by this parameter and this feature is not valid in broadcast mode. Keep in mind that selecting a larger value for Random Back Off will increase the overall latency of the AC4424. The latency calculation becomes:

Worst Case Latency = 8ms Hop * # of retries * Maximum Random Value

[multiply by 16ms if using Full Duplex mode]

Latency is a very important consideration when using a wireless device. The AC4424 has a 256 byte interface buffer. If, due to latency, the radio cannot send the data out over the RF as fast as data is coming into the radio over the serial interface, the buffer will eventually fill up. If data continues coming into the radio once the buffer is full, the buffer will overflow and the new incoming data will be lost. It is strongly recommended that the radio host monitor the CTS pin to avoid this situation. The transceiver asserts this pin high as the buffer is filling to signal the OEM Host to stop sending data. The transceiver will take CTS Low once the buffer becomes less full.

• 00h – Wait 1 packet time, then retry (Random Back Off is disabled)

• 01h – Wait 1 – 2 packet times, then retry

5.2.55.2.4

5.2.55.2.5

In Half Duplex mode, the AC4424 will send a packet out over the RF when it can. This can cause packets sent at the same time by a Server and a Client to collide with each other over the RF. To prevent this, Full Duplex Mode can be enabled. This mode restricts Clients to transmitting on odd numbered frequency “bins” and the Server to transmitting on even

Interface Timeout

Interface Timeout – Interface Timeout specifies a maximum byte gap in between consecutive

Interface timeout is adjustable in 160uS decrements. The actual timeout created by Interface Timeout is equal to the 2's complement of Interface Timeout times 160uS. The default value for Interface Timeout is F0H or 2.56ms.

• The RF Exposure Warning (next page) also must be printed inside the equipment’s user manual.

The FCC/IC approval was granted with the module classified as mobile (ie. the antenna is >20 cm from the human body with the exception of hands, wrists, feet, and ankles). The end user needs to ensure that the antenna location complies with this or retest for portable classification (less than 2.5 cm with the same exceptions as mobile) at their own expense.

FCC regulations allow the use of any antenna of the same type and of equal or less gain. However the antenna is still required to have a unique antenna connector such as MMCX or reverse SMA. On the following page is a table of antennas available through AeroComm. Any different antenna type or antenna with gain greater than those listed must be tested to comply with FCC Section 15.203 for unique antenna connectors and Section 15.247 for emissions at user’s expense.
