NetAXS™ NX4L1 Installation Guide
Installation
Note:
If an NX4IN is not required in a system, start addressing the output modules at DIP switch 3. If
an NX4IN is configured with an address other than 1 or 2, the NetAXS panel will not communicate
with it. Likewise, if an NX4OUT is configured with an address other than 3 through 6, the NetAXS
panel will not communicate with it.
The NetAXS board and the NX4L1 is not intended to provide either module power or module output
load power for downstream I/O. A separate 24 VDC supply should be used to provide power to all
downstream modules and output loads. For some installations, the noise immunity improves if the
NetAXS common is connected to the 24 V Return wiring for the downstream modules. This
connection is not needed for most installations.
Jumper settings JP1 - CLOSED (if the module is
the last module on the
downstream bus), OPEN (if the
module is not the last module on
the downstream bus)
JP2 - any setting
JP3 - any setting
JP4 - NORMAL
(Positions 1 and 2)
NX4OUT DIP switches Address (switches 1–6) -
3 through 6
Baud rate (switches 7 and 8) -
7 = OFF, 8 = ON
OP Mode (switches 9 and 10) -
9 = OFF, 10 = OFF
Jumper settings JP1 - CLOSED, positions 2 and
3 (if the module is the last
module on the downstream bus);
OPEN, positions 1 and 2 (if the
module is not the last module on
the downstream bus)
