6.0 Register/Command Reference
Values (0-255)
S245 (MESH) Cost of Hop
100
Cost of one hop in mesh routing. When choosing the best route, the cost of
each route must be considered. Cost of Hop allows a user to influence the
relationship between the cost of RSSI and the Cost of Each hop. See Section
3.2.7 Routing for a detailed explanation.
Values
S244 (MESH) Channel Access Mode
0 - Aloha
1 - RTS/CTS
2– TDMA
Channel Access Mode. This register defines how devices access the channel
when they have data to transmit.
0 - Aloha - Units use Carrier Sense (CSMA) to access the channel, if
available, and send data. Register S115 can be set to
configure the randomness at which devices access the
channel to avoid collisions. Default for coordinator.
Values (1-65535)
S235 (PP) PP Routing TTL, sec
30
Routing Time to Live in seconds. (1-65535). Defines the aging interval for
routing information in PP Mode.. 65535—never age. Default is 30 seconds.
Values (1-65535)
S236 Max Buffer Out Storage
255
Maximum buffer out storage. Limits the number of buffers waiting to be output
to the user on COM1 (1-65535), default is 255. Normally should not be
changed.
1 - RTS/CTS - When units wish to transmit, they request a channel (RTS) from the associated coordinator. The
Coordinator will respond immediately (CTS) if the channel is successfully allocated. Default for
secondary coordinators and remotes.
2 - TDMA - Transmission on slot. See S221.
Values (N/A)
S247 Country Code (Read Only)
Read Only, Varies
This register shows the currently factory set country code. This is a read only
register and can only be modified at the factory.
Values (1-254)
S234 (PMP) Master Ch. Req. Timeout
1
After the master releases the channel, it will wait for the S234 number of hop
intervals to allow the slaves to send channel requests before the master
arbitrates the channel.
When there are many slaves that may want to request the channel at the same
time, setting this register to a bigger number will help ensure that the channel
arbiter in the master will allocate the channel fairly - new modems will be given
higher priority over modems that were recently allocated the channel.
