XStream‐PKG‐R™ RS‐232/485 RF Modem – Product Manual v5.x00 [2006.02.24]
LH (Wake-up Initializer Timer) Command
MD (RF Mode) Command
MK (Address Mask) Command
<Sleep (Low Power)> LH Command adjusts the
duration of time for which the RF initializer is
sent. When receiving modems are put into Cyclic
Sleep Mode, they power-down after a period of
inactivity [specified by ST (Time before Sleep)
command] and will periodically awaken and listen
for transmitted data. In order for the receiving
modems to remain awake, they must detect
~35ms of the wake-up initializer.
LH Command must be used whenever a receiver
is operating in Cyclic Sleep Mode. This lengthens the Wake-up Initializer to a specific amount of
time (in tenths of a second). The Wake-up Initializer Time must be longer than the cyclic sleep
time that is determined by SM (Sleep Mode) Command. If the wake-up initializer time were less
than the Cyclic Sleep interval, the connection would be at risk of missing the wake-up initializer
transmission.
Refer to the figures in the Sleep Mode section [p16] to view diagrams of correct and incorrect
configurations. The images help visualize the importance that the LH value be greater than the
SM cyclic sleep value.
<Networking & Security> The MD command is
used to select/read the RF Mode (Peer-to-peer,
Multi-Stream or Repeater Modes) of the modem.
Multi-Streaming Mode enables exclusive
connections in point-to-multipoint networks.
Refer to the Multi-Streaming Mode section [p48]
for more information regarding how these
parameter values affect other parameter values.
Repeater Mode enables longer range via an
intermediary modem. When MD=3, the modem
will act as a “store and forward” repeater. Any
packets not addressed to this node will be
repeated. A Repeater End Node (MD=4) handles
repeated messages, but will not forward the data
over-the-air. Refer to the Repeater Mode section
[p43] for more information.
<Networking> MK Command is used to set/read
the Address Mask.
All data packets contain the Destination Address
of the transmitting modem. When an RF data
packet is received, the transmitter’s Destination
Address is logically “ANDed” (bitwise) with the
Address Mask of the receiver. The resulting value
must match the Destination Address or the
Address Mask of the receiver for the packet to be
received and sent out the modem’s DO serial
port. If the “ANDed” value does not match either
the Destination Address or the Address Mask of
the receiver, the packet is discarded. (All “0”
values are treated as “irrelevant” values and are ignored.)
