The OEM Host issues this command to change the transceiver
operation between Addressed Packets and Broadcast Packets. If
Addressed Packets are selected, the transceiver will send all packets to
the transceiver designated by the Destination Address programmed in
the transceiver. If Broadcast Packets are selected, the transceiver will
send its packets to all transceivers on that network. Setting bit-7 of API
Control to 1 can also enable Broadcast Packets.
Command: 0xCC 0x08 Data1
Number of Bytes Returned: 2
Response: 0xCC Data1
Parameter Range: Data1 = 0x00 for Addressed, 0x01 for
Broadcast
W r i t e D e s t i n a t i o n A d d r e s s
The OEM Host issues this command to the transceiver to change the
Destination Address.
Note: Only the three Least Significant Bytes of the MAC Address are
used for packet delivery.
Command: 0xCC 0x10 MAC3 MAC2 MAC1
Number of Bytes Returned: 4
Response: 0xCC MAC3 MAC2 MAC1
Parameter Range: 0x00 - 0xFF corresponding to 3 LSB’s of
destination MAC Address
R e a d D e s t i n a t i o n A d d r e s s
The OEM Host issues this command to the transceiver to read the
destination address.
Note: Only the three Least Significant Bytes of the MAC Address are
used for packet delivery.
Command: 0xCC 0x11
Number of Bytes Returned: 4
Response: 0xCC MAC3 MAC2 MAC1
Parameter Range: 0x00 - 0xFF corresponding to 3 LSB’s of
destination MAC Address
A u t o D e s t i n a t i o n
The Host issues this command to change the Auto Destination setting.
When issuing this command, the Auto Destination setting will only be
changed if the corresponding enable bit is set (Control1 Parameter,
EEPROM address 0x56, bits-4,5)
Command: 0xCC 0x15 Data1
Number of Bytes Returned: 2
Response: 0xCC Data2
Parameter Range: Data1 = bit-0: Auto Destination, bit-4:
Enable Auto Destination modification; Data2 = bit-0: New
Auto Destination setting, bits 1 - 7:0
R e a d D i g i t a l I n p u t s
The OEM Host issues this command to read the state of both digital
input lines.
Command: 0xCC 0x20
Number of Bytes Returned: 2
Response: 0xCC Data1
Parameter Range: Data1 = bit-0: GI0, bit-1: GI1
R e a d A D C
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.
Analog Voltage = (10 bits / 0x3FF) * 3.3V
Temperature (
o
C) = ((Analog Voltage - 0.3) / 0.01) - 30
Command: 0xCC 0x21 Data1
Number of Bytes Returned: 3
Response: 0xCC Data2 Data3
Parameter Range: Data1 = 0x00: AD In, 0x01: Temperature;
Data2 = MSB of requested 10-bit ADC value; Data3 = LSB of
requested 10-bit ADC value
