MODULE CONFIGURATION SETTINGS
In order for the 900 Series modules to communicate properly the chassis must be populated with modules from
the top
slot down as shown below. In addition, JP1 and JP2 jumpers (located on top side of all modules) must be
configured as indicated below.
Note: The power source must be disconnected from the 900B chassis prior to removing and inserting modules. This
unit is not hot swappable.
One Slot Configuration - When installing a single 902FX, 904FX, or
908TX module in the top slot of the 900B chassis… Configure the
module as follows:
JP1: pins 1 & 2 shorted
JP2: pins 1 & 2 shorted
Two Slot Configuration - When installing two 902FX, 904FX, and/or
908TX modules in the top two slots of the 900B chassis… Configure
both modules as follows:
JP1: pins 1 & 2 shorted
JP2: pins 3 & 4 shorted
Three Slot Configuration - When installing three 902FX, 904FX, and/or
908TX modules in all three slots of the 900B chassis… Configure all
modules as follows:
JP1: pins 3 & 4 shorted
JP2: pins 3 & 4 shorted
908TX Module - At power cycle, all LED’s flash on for approximately two seconds, and
then return to proper state. Green LED will light when Power is connected.
902FX & 904FX Modules - At power cycle, only the LED’s on the first
port flash on to indicate the reset condition, and then return to their proper
state. All other reports remain off during reset. This is normal behavior.
Green LED will light when Power is connected.
In order to verify the module jumper (JP1 & JP2) settings have been set correctly, for units which have the
N-View option turned on, you should install N-ViewOPC Server software on a PC connected to the LAN.
The software is freely distributed on the ProductCD and our web site ( http://n-tron.com/nview.zip ). Once N-
ViewOPC is installed, you should view the Ports Counter page to remotely monitor each connected port. You
may find it helpful to Copy [Alt]+[PrintScreen] the Port Counter information for each port and Paste
[Control]+[V] into a Windows document for further review. Please consult your N-View OPC Server Manual
for additional information.
