... E,O,M,S 3.3.2 Latency Note about Timing: The AC4486 is a single frequency radio design. Though it does not hop from one frequency to another, packet delivery timing is based on a fictitious hop, which occurs every 20ms. This maximizes the use of the AC4486 resources and makes timing much more deterministic. For ease of understanding, the documentation will still refer to a hop ...

... ONTROL OMMANDS The AC4486 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. Note: Do not to modify undocumented static addresses as undesired operation may occur. All “ ...

... AC4486 Specifications 4.6.4 Server/Client Command The Host issues this command to change the mode (Server or Client) of the transceiver and can force the transceiver to actively begin synchronization. The transceiver will not begin acquisition sync until its Range Refresh timer expires; therefore it is recommended that the host uses the commands which force acquisition sync ...
Page 27
... AC4486 Specifications 4.6.6 Sleep Walk Power-Down Command After the Host issues the power-down command to the transceiver, the transceiver will de-assert 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 ...

... AC4486 Specifications 4.6.15 Auto Destination The Host issues this command to change the settings for Auto Destination. When issuing this command, the Auto Destination setting will only be changed if the corresponding enable bit is set. Host Command: Byte 1 = CCh Byte 2 = 15h Byte 3 = Data1 Where: ...
Page 32
... AC4486 Specifications 4.6.17 Read ADC The Host issues this command to read any of the three 10 bit onboard A/D converters. Because the RF is still active in on-the-fly mode, the transceiver will not process the command until there is no activity on the network. Therefore, the Read RSSI command is useful for detecting interfering sources but will not report the RSSI seen from a remote transceiver on the network ...
Page 33
... AC4486 Specifications 4.6.18 Report Last Valid RSSI As RSSI values are only valid when the local transceiver is receiving a RF packet from a remote transceiver, instantaneous RSSI can be very tricky to use. Therefore, the transceiver stores the most recent valid RSSI value. The Host issues this command to request that value. Note: This value will default to FFh on a Client and 00h on a Server if no valid RSSI measurement has been made since power-up ...

... AC4486 Specifications 4.6.21 Set Max Power The Host Issues this command to limit the maximum transmit power emitted by the transceiver. This can be useful to minimize current consumption and satisfy certain regulatory requirements. Host Command: Byte 1 = CCh Byte 2 = 25h Byte 3 = Data1 Where: Data1 = New Max Power ...
Page 36
... AC4486 Specifications 4.6.24 Deep Sleep Mode The Host issues this command to put the transceiver into Deep Sleep mode. Once in Deep Sleep, the transceiver disables all RF communications and will not respond to any further commands until being reset or power cycled. This command is valid for both Servers and Clients. ...
Page 37
... AC4486 Specifications 4.6.27 EEPROM Byte Write Upon receiving this command, a transceiver will write the data byte to the address specified but will not echo it back to the Host until the EEPROM write cycle is complete. The write can take as long as 10ms to complete. Following the write cycle, a transceiver will transmit the data byte to the Host. ...
Page 38
... 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 AC4486 is a single frequency transceiver, though it still generates a Hop Frame signal every time it transmits a timing beacon. ...
Page 39
... AC4486 Specifications 5.1.4 CTS Handshaking (pin 7) The AC4486 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 loss will occur. The transceiver prevents this loss by asserting CTS High as the buffer fills up and taking CTS Low as the buffer is emptied. CTS On in conjunction with CTS On Hysteresis control the operation of CTS ...

... Channel Number in the same coverage area as the interference between the two Servers will severely hinder RF communications. The AC4486 runs a Peer-to-Peer type architecture where all transceivers, whether Servers or Clients, can communicate with all other transceivers. To prohibit transceivers from receiving broadcast packets, Unicast Only can be enabled. ...
Page 43
... Aerocomm. 5.2.4 Duplex Mode In Half Duplex mode, the AC4486 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 “ ...

... RF Channel Number – RF Channel Number selects the operational frequency band of the transceiver. The AC4486 provides two channels of operation based on output power and transmit duty cycle. The AC4486 does not restrict the duty cycle or power output and the OEM is responsible for ensuring that these requirements are met. This information is provided in the chart below: 4 57,600 is the default baud rate ...

... D0 – D6h. 5.2.8 Auto Config The AC4486 has several variables that control its RF performance and vary by RF Mode and RF Architecture. Enabling Auto Config will bypass the value for these variables stored in EEPROM and use predetermined values for the given mode. Below is a list containing all of the variables affected by Auto Config and their respective predetermined values (values are all in hexadecimal format) ...
Page 46
... Enabling One Beacon mode causes the beacon to only be sent once per complete hop cycle. Because the AC4486 is single frequency, the beacon is not required for the Client to locate the Server. Therefore, One Beacon mode is enabled by default to minimize the amount of time spent sending beacons. Table 12 – ...
