Overview
OverviewOverview
Overview
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 on-board 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 Peer-to-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.
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.
The OEM is responsible for ensuring the final product meets all FCC and/or appropriate regulatory
agency requirements listed herein before selling any product.

9600_BAUD – When pulled logic Low before applying power or resetting the transceiver’s
serial interface is forced to a 9600, 8, N, 1 rate. To exit, transceiver must be reset or power-
cycled with 9600_Baud logic High.
Packet Frame – When programmed in EEPROM, Packet Frame will transition logic Low at the
start of a received RF packet and transition logic High at the completion of the packet.
13 O RSSI Received Signal Strength - An analog output giving a relative indication of received signal
strength while in Receive Mode
14 I WR_ENA EEPROM Write Enable – When pulled logic Low, it allows the Host to write the on-board
EEPROM. Resetting the transceiver with this pin pulled Low may corrupt EEPROM data.
15 I UP_RESET RESET – Controlled by the AC4424 for power-on reset if left unconnected. After a Stable
power-on (50ms) a 50us logic High pulse will reset the AC4424. Do not power-up the
transceiver with this pin tied Low.
16 GND GND Signal Ground
17 I Command/Data When logic Low, transceiver interprets Host data as command data. When logic High,
transceiver interprets Host data as transmit data.

Care should be taken when selecting transceiver architecture as it can have serious effects on data
rates, latency timings, and Overall System Throughput. The importance of these three characteristics
will vary from system to system and should be a strong consideration when designing the system.

Serial Interface Data Rate
The Serial Interface Data Rate is programmable by the Host. This is the rate the Host and transceiver
communicate over the serial bus. Possible values range from 110 bps to 288,000 bps. The only
supported mode is asynchronous – 8-bit, No Parity, 1 Start Bit, and 1 Stop Bit.

The configuration set allows the Host to modify the operation of the transceiver. If the Command/Data
pin (Pin 17) is pulled logic Low, a transceiver will interpret incoming Host data as Command Data.
The Host can then read and write parameters using the various configuration commands listed below.
To exit Configuration Mode, the Host must perform a hardware or power-on reset or issue an Exit

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).

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.

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

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

RSSI (pin 13)
Received Signal Strength Indicator is used by the Host as an indication of instantaneous signal
strength at the receiver. The Host must calibrate RSSI without a RF signal being presented to the
receiver. Calibration is accomplished by following the steps listed below to find a minimum and
maximum voltage value.
1) Power up only one Client (no Server) transceiver in the coverage area.
2) Measure the RSSI signal to obtain the minimum value with no other signal present.
3) Power up a Server. Make sure the two transceivers are in close proximity and measure
the Client’s peak RSSI once the Client reports In Range to obtain a maximum value at full
signal strength.
Figure 1 shows approximate RSSI performance. Output is 1.20V to 4.50V.

Transmit Retries is used to increase the odds of successful delivery to the

sender does not receive this acknowledge, it will assume the packet was never received and retry the

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 frequency bins. Though the RF
hardware is still technically half duplex, it makes the radio seem full duplex. This can cause overall
throughputs to be cut in half. Note: All transceivers on the same network must have the same setting

Interface Timeout – Interface Timeout specifies a maximum byte gap in between consecutive bytes.
When that byte gap is exceeded, the bytes in the transmit buffer are sent out over the RF as a
complete packet. 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
