Read ADC
The OEM Host issues this command to read any of the
three onboard 10 bit A/D converters. Because the RF
is still active in on-the-fly Command 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. The equations for converting these 10
bits into analog values are as follows:
Command: 0xCC 0x21 Data1
Number of bytes Returned: 3
Response: 0xCC Data2 Data3
Parameter Range:
Data1 = 0x00 – AD In
Data2 = MSB of requested 10 bit ADC value
Data3 = LSB of requested 10 bit ADC value
Write Digital Outputs
The OEM Host issues this command to write both
digital output lines to particular states.
Note: This command should be used only when
Protocol Status (0xC2) is not set to 0xE3.
Command: 0xCC 0x23 Data1
Number of bytes returned: 2
Response: 0xCC Data1
Parameter Range:
Data1 = bit 0 – GO0, bit 1 – GO1
Probe
Enabling bit-6 of API Control will enable this command.
When the OEM Host issues this command, the
transceiver sends out a query every 500ms. The
transceivers, which receive this query, will randomly
choose a query to respond to. This helps prevent
multiple transceivers from trying to respond to the
same Probe at the same time. After responding to a
Probe, the transceivers will wait for approximately
10sec before responding to any other probe.
Note: While executing the Probe command, the
transceiver can perform normal RF communications.
Temperature (°C) = ((Analog Voltage - 0.3) / 0.01) – 30
RSSI Value (dBm) = -105 + (0.22 * (0x3FF – 10 bits))
Analog Voltage = (10 bits / 0x3FF) * 3.3V

Command: 0xCC 0x8E Data1
Number of bytes returned: 2
Response: 0xCC Data1
Parameter Range:
Data1 = 0x00 – Disable Probe
Apart from the Transceiver response for the command,
there are two other responses that return vital data to
the OEM Hosts. This data is very useful to monitor the
network and make decisions on rerouting data packets
accordingly.
Response 1: Remote Transceiver’s response to its
OEM Host on receiving a Probe.
This response helps a radio identify the radio that
probed it.
which is helpful in determining the strength of the
wireless link between radios.
Note: This response is received only when Probe
Report (0xC9) is set to 0xE3.
Response2: Transceiver’s response to its OEM Host on
hearing
Acknowledge):
This response helps a radio identify the radio that
received its probe. This response also returns RSSI and
RSSI* values, which can be analyzed to determine how
strong the link is.
EEPROM Byte Read
Upon receiving this command, a transceiver will
respond with the desired data from the address
requested by the OEM Host.
Command: 0xCC 0xC0 Data1 Data2
Number of bytes returned: 4+
Response: 0xCC Data1 Data2 Data3
Parameter Range:
Data1 = EEPROM address
Data2 = Length (0x01-0x80)
Data3 = Requested data
Byte 1 = 0x86
Byte 2 = RSSI (How strong the remote transceiver
Bytes 3 – 5 =3 bytes of MAC Address of the radio
Byte 1 = 0x87
Byte 2 = RSSI (How strong the remote transceiver
Byte 3 = RSSI* (How strong the local transceiver
