Daisy Chaining
To manage even more devices, up to 15 additional PN0108 Stations can be
daisy chained down from the top level unit. Up to 128 devices can be managed
on a complete installation. To set up a daisy chained installation do the
following:
1. For each PN0108 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 PN0108's PON
OUT port to the child PN0108's PON IN port.
2. Power up the daisy chained PN0108 Stations in sequence starting with the
highest level parent and working down. In each case, wait for the
PN0108'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 unit is
01
; the ID for the Second Stage unit is
02
, etc.
3. After all the PN0108 Stations are up, power on the devices.
