Daisy Chaining
To manage even more devices, up to 15 additional PN9108U Stations can be
daisy chained down from the top level unit. In this way, up to 128 devices
can be managed on a complete installation. To set up a daisy chained
installation do the following:
1. For each PN9108U Station that you add to the chain, use the DB-9 to
DB-9 PON cable that was provided with it to connect the parent
PN9108U’s PON OUT port to the child PN9108U’s PON IN port.
2. Power up the daisy chained PN9108U Stations in sequence starting with
the highest level Station and working down. In each case, wait for the
PN9108U’s Station ID to be ascertained and displayed on the Station ID
LED before powering on the next unit.
The Station ID for First Stage (top level) unit is 01; the ID for the Second
Stage unit is 02, etc.
3. After all the PN9108U Stations are up, power on the devices.
