Can NBPD0150 and NBPD0170 be daisy chained off of the same NBRK0570? If so, how often would an additional power supply be needed and where?

Such as:

570 > [170 > 150] > [170 > 150 ] > [170 > 150] > etc.

We are thinking about a design that involves a 170 and 150 on each rack, for door/card access sensors and temp/humid sensors respectively.

Douglas,

Mixing sensors pods and rack access pods can make it difficult to judge where to add external power supplies.  The users guide recommends adding one every 10 sensor pods or 4 rack access pods.  My recommendation would be to add one every 3 racks (3 150s and 3 170s).  If power issues with PODs disconnection and reconnecting occur, additional power supplies would need to be added.  So the setup would look like this:

570 > [170 > 150] > [170 > 150 ] > [170 > 150 ] > [170(external power) > 150] > [170 > 150] > [170 > 150 ] > [170(external power) > 150] > [170 > 150] > [170 > 150 ] > [170(external power) > 150] > [170 > 150] > [170 > 150 ] > 170(external power).

Please keep in mind that the NetBotz 570 only support 12 sensor pods and 13 rack access pods.

If you are not looking to add more than a few sensors per rack, you could run a 150 only every few racks and then just run the sensors to the racks next to the rack that has the 150.

Regards,

Cory
