7) Jumper Settings
There are two jumpers located on the removable AS-i address board (node). These jumpers are for selecting
external power (through power connector) or internal power (through communication connector) for the
outputs. The Numatics’ AS-i nodes are factory set to operate using external auxiliary power (black cable) for
coil outputs. By changing the power jumpers on each removable AS-i circuit board (node), as shown above,
output power can be alternatively supplied by the network (yellow) cable. When powering outputs from the
network (yellow) cable there is a 1 Amp total current limitation per AS-i node board (thus a 2 node module can
only draw a maximum of 2 Amps total from the network power).
Power Rating
Maximum system current capability is 1 Amp. when powering outputs through the network cable.

8) Standard vs. Extended Addressing
There is a choice between standard and extended addressing. Extended addressing allows the user to use 62
addresses on the network but limits the user to 3 outputs per AS-i node. Standard addressing allows for 31
addresses per network and 4 outputs per AS-i node. The AS-i Communication Node I/O Chart below includes
the part numbers of both the standard and extended addressing AS-i modules.
Please be aware of the overall current requirements when driving output
devices from network power so the appropriate current limits of network
power are not exceeded.
