Daisy Chaining
To manage even more devices, up to 15 additional PN9108 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 PN9108 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 PN9108's PON
OUT port to the child PN9108's PON IN port.
2. Power up the daisy chained PN9108 Stations in sequence starting with the
highest level Station and working down. In each case, wait for the
PN9108'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 PN9108 Stations are up, power on the devices.
