3.If you are connecting more than one EMX 156 module

to your Infinet controller, connect the second one to the

bottom of the first.

4.Set the BOARD switch (upper right) to 1 on the first EMX

156, and the BOARD switch to 2 on the second EMX 156.

If you do not plan to connect more than one EMX 156

module, set the BOARD switch to 1.

Never set two modules of the same model number to the

same board number.

3. Connect the External Power Supply

(if necessary)

If you are installing multiple modules, you may need an

external power supply. To determine what you need, refer

to the ACC EMX Modules Configuration Guide.

Figure 2 shows where you connect the external power supply

to the 2-pin Berg type connector on the EMX 156.

4. Reposition Jumper of One Module

The Berg type connector immediately to the left of the ex-

ternal power supply connection has a jumper that you

reposition to indicate you are using external power.

Figure 3 shows the jumper in the two possible positions, one

for the internal power supply, the other for the external. Move

the jumper to the external power supply position.

You change the jumper position only on the module or mod-

ules connected to the external power supply, not on any other

modules.

Note

ule(s) actually connected to an external power supply. Never

change the jumper position of other modules.
