REPLACING I/O MODULES
In order to replace an input or output module - e.g. if more inputs or outputs are required
- rst switch the Compact Stagebox OFF and unplug the mains cable(s).
• Observe the precautions for handling devices sensitive to electrostatic discharge – refer to p. 5.
• For all screws in question a no. 2.5 Allen screwdriver is used.
• Remove the top cover of the Compact Stagebox (2 countersunk screws M4x8 on top, 13 screws
M4x6 around the upper edge).
• Then remove the module concerned. Unplug the at cable from the backplane PCB and the supply
loom from the module.
• Remove the 4 screws M4x6 at the module’s edges.
• Insert the new module and x it with the 4 screws. Connect the at cable to the corresponding
socket on the backplane PCB (for correct connection refer to the illustration below).
• Connect the supply loom to the module. Supply looms are identical for input and output modules,
no particular order has to be followed when reconnecting them. Like the power connections in a PC,
there is one connector more than modules to feed; the fourth connector is not used.
• For xing the top cover it is recommended to tighten all screws only after all of them have been
inserted a few turns into their threads.
• Connect the Compact Stagebox to the mains again, switch it on and press the RECONFIG button
with a small tool (e.g. the Allen screwdriver used before).
• Remember that the new input/output count needs to be congured in your console’s I/O mapping.
Please refer to its user guide.

Output Modules

The 3 module slots are labeled A, C and E; they correspond to the connectors of the backplane PCB ac-
cording to the illustration above. There are 3 connectors on the left for input modules, and 3 on the right
for output modules. Modules must be connected to the correct connector in order to have a correct as-
signment of input and/or output channels.
In the standard conguration (2 input modules in slots A and C, and 1 output module in slot E) the mod-
ules are connected as follows:
Input module A è top connector on the left side of the backplane (P2)
Input module C è middle connector on the left side of the backplane (P13)
Output module E è bottom connector on the right side of the backplane (P20).
