messages sent by the slaves will be received only by the master unit.
For example, imagine a installation where doors are controlled by access card readers. Each reader uses serial
communications to report access information back to a hub. A single master unit could be used to receive serial
information from each of the individual doors. The master unit could also be used to broadcast information back to all
readers, provided you don't mind them all receiving the same message.
To pair a point-to-multipoint configuration:
In a point-to-multipoint configuration, your master device sends communications heard by each of the slave devices,
but the slaves can only send data back to the master.
1. Make sure all devices are powered.
2. On the master SNAPlink device, press the button four times within a 3-second period. LED A should switch to
flashing amber. Again, push the button four times within a 3-second period. LED A should switch to a slow
flash between green and amber, indicating that it is a master unit.
3. For each slave SNAPlink device, press the button four times within a 3-second period. LED A may briefly
switch to flashing amber, but should quickly go to a solid green, indicating that it has found its master. (If you
have an exceptionally noisy RF environment, you may find that one or more of the slave devices have LED A
flashing amber rather than green. If this occurs, you should consider switching your devices to a different
SNAP channel, which would use a different radio frequency. You can make this change using the EasySet
software or using the DIP switches inside the SNAPlink device.)
NOTE:
If you have an exceptionally noisy RF environment, you may find that one or both of the devices have
LED A flashing amber rather than green. If this occurs, you should consider switching your devices to a different
SNAP channel, which would use a different radio frequency. You can make this change using the EasySet
software or using the DIP switches inside the SNAPlink device.
