NI-3101-SIG Signature Series NetLinx Integrated Controller
Input/Output (I/O) Port: Connections and Wiring
The I/O port responds to either switch closures or voltage level (high/low) changes, or it can be used for logic-
level outputs.
Up to eight devices may be connected to the I/O connectors on the NI-3101-SIG (FIG. 9). 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 VDC) as a Push, and a high
signal (3.5 - 5 VDC) as a Release (this IO port uses 5V logic but can handle up to 12V without
harm).
When used for outputs, the I/O port acts as a switch to GND and is rated for
200 mA @ 12 VDC. This device can use up to 8 I/O ports.
The PWR pin provides +12 VDC @ 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 - 8.
IR/Serial Port: Connections and Wiring
Up to eight IR- or Serial-controllable devices may be connected to the IR/Serial connectors on the rear of the
NI-3101 (FIG. 10). These 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. A data 0 - 5 VDC device may
also be connected. These units come with two CC-NIRC IR Emitters (FG10-000-11).
