9XTend™ OEM RF Module - Product Manual v2.x6x

Refer to the ‘Multi-transmit Mode’ section [p46] for more information.
MY (Source Address) Command
<Networking & Security> The MY command is
used to set/read the Source Address of the RF
module.
Refer to the DT command and the 'Addressing'
section [p45] for more information.
NB (Parity) Command
<Serial Interfacing> The NB command is used to
select/read the parity settings of the RF module
for UART communications.
PB (Polling Begin Address) Command
<Networking & Security> PB command is used to
set/read the module’s Polling Begin Address - the
first address polled Polling Mode is enabled.
Polling Operations: The ‘Polling Base’ (MD = 3)
cycles through a sequential range of addresses,
polling each ‘Polling Remote’ (MD = 4). The base
then waits for a response & proceeds to the next
‘Polling Remote’. Each ‘Polling Remote’ responds
by sending the data from the Data In buffer fol-
lowing the RB & RO parameters. When there is no
eligible data to send, the ‘Polling Remote’ will not respond. The
‘Polling Base’ will move to the next
address in the polling sequence after a short delay.
PD (Minimum Polling Delay) Command
<Networking & Security> The PD command is
used to set/read Polling Delay (Base, MD=3) or
Polling Timeout (Remote, MD=4).
Polling Delay (Base) is the time between polling
cycles. The Polling Base will start the polling cycle
after sending the first poll. After the polling cycle
has completed, the timer is restarted.
Polling Timeout (Remote) is the amount of time
the remote unit will hold data from the serial port
before discarding it. Data entered within the PD
time of the pol
l is transmitted and not discarded.
