I/O
The I/O port (available only on the MCP-108) responds to switch closures and voltage level (high/low) changes, or can be used for
logic-level outputs. The +12 pin pr12 V
DC
@ 200 mA and is designed as a power output for the PCS Power Current
Sensors, VSS2 Video Sync Sensors (or equivalent). The GND connector is a common ground and is shared by all I/O ports. A
common ground is shared with I/O ports 1 - 2.
FIG. 8 displays the I/O connector.

I/O port
CAUTION:
Improper wiring could damage your ControlPad. The CP-3008 ControlPad has the ground and power signals in swapped
positions on the I/O port. If you are replacing a CP-3008 ControlPad with the MCP-108, you may need to make a wiring change in
your I/O connector to avoid damaging the MCP-108.
A contact closure between the GND and an I/O port is detected as a Push.
When used for voltage inputs, the I/O port detects a low signal (0 - 1.5 V
DC
) as a Push, and a high signal
(3.5 - 5 V
DC
) as a Release. (This I/O port uses 5V logic but can handle up to 12V without harm.)
The following table provides wiring requirements for the I/O port:
IR/Serial
You can connect up to two IR-controllable devices to the IR connectors to the Massio ControlPads. The MCP-106 features only one
IR connector; the MCP-108 features two connectors.
The IR connectors support generating carriers up to 1.142 MHz. The IR connectors accept an IR Emitter (CC-NIRC) that mounts
onto the device's IR window, or a mini-plug (CC-NSER) that connects to the device's control jack.
You can also connect a data (0 - 5 V
DC
) device.
FIG. 9 displays the IR/SERIAL connector.

IR/SERIAL connector
The IR/Serial connector wiring specifications are listed in the following table.
IMPORTANT:
The IR positive (+) and negative (-) connections are positioned from left to right. The signal connector is located on the
left side of the IR connection while the ground connector is located on the right side.
