10.4.74.28 RadioTxSubID
In a MultiPoint Network (with Subnet IDs disabled), a Slave or Repeater will connect with the first
Repeater or Master that it hears with the same Network ID. There are scenarios, however, where
communications need to be forced to follow a specific path. The Subnet ID is particularly helpful
to force two Repeaters in the same network to operate in series rather than in parallel; or, if
desired, to force Slaves to communicate to a specific Repeater for load balancing purposes.
There are two components to the Subnet ID:
1. Receive Subnet ID (RX ID): This setting identifies which transceiver a Repeater or Slave will
listen to. The RX ID has no effect on a radio configured as Master and should be left at the
default value of 15.
2. Transmit Subnet ID (TX ID): This setting identifies the ID on which this device transmits, and
in turn which devices will listen to it. The TX ID Subnet ID setting is only relevant for
MultiPoint Masters or Repeaters.
Default Setting:The default (disable) setting for both RX ID and TX ID is 15 (0xF), which is a visual
way to indicate that the device is the final in the line of communication and does not use a
subnet ID. A Multipoint Slave with a Subnet ID of 15,15 (0xF,0xF) does not roam from one
Repeater or network to the next, it only links to a Master or Repeater that has either a TX ID
setting of 0 or 15.
l For the Master, the default setting causes the Master to actually transmit on 0, and it will
receive any Subnet ID.
l For Slaves, the default setting (15,15) disables the use of Subnet IDs; they will connect to
the first Master or Repeater that has the same Network ID as the Slave.
l If Subnet IDs are to be used, the downstream radios (slave or repeater) that need to
connect directly to the Master will need their RX ID set to same value as the Master radio TX
ID. If the Master radio is set to its default value of 15 the slave or repeaters that need to
connect directly to the Master must have a RX ID setting of 0.

Access Wi-Fi settings, using Device Configuration Utility. Clicking on a setting in Device
Configuration Utility also provides information about that setting. These settings are available for
data loggers with integrated WIFI modules.
