Panel Description
Power LED
- Solid ON (red): 12V input power supply is on
- OFF
VDC Output LED
- Solid ON (red): 'VDC Output' port is supplying 12V
- OFF: 'VDC Output' port is disabled
Status LED
- Blinking ON (red): normal operation and good connection to the SynLInk PDU Controller
- OFF: No connection to SynLink PDU Controller
Reset Button
- Push and hold for 5 seconds to Reset
Digital Input LEDs (1-6)
- Solid ON (green): port detects logic HIGH
- OFF: port detects logic LOW
Relay Output LEDs (1-6)
- Solid ON (green): The relay is in the Normally Closed (NC) position, with the Common (COM) terminal making contact with the Normally Closed terminal
- OFF: The relay is in the Normally Open (NO) position, with the Common (COM) terminal making contact with the Normally Open terminal
User Switch
- ON: All relays are switched to the Normally Closed (NC) position, with the Common (COM) terminal making contact with the Normally Closed terminal
- OFF: All relays are switched to the Normally Open (NO) position, with the Common (COM) terminal making contact with the the Normally Open terminal. Any attempts to turn ON the relays using the web interface is ignored by the HUB while the User Switch is OFF.

Port Description
Power
12V power supply input. Use the power supply included.
VDC Output
Current limited 12V power supply output. Output current limited to 4A.
Digital Input
6x optically isolated digital input ports with pull-up option to ‘HI’ (VDC). See example wiring diagram on Page 5. If the port is pulled up to ‘HI’, the HUB detects logic high. If the port is pulled down to COM/ground, the HUB detects logic low.
Relay Output
6x dry contact SPDT relay outputs. Each port can be individually controlled (open/closed) and programmed for automation on the SynLink controller interface. ‘O’ = Normally Open Relay Contact. ‘M’ = Common. ‘C’ = Normally Cosed Relay Contact.
Sensor Port
Interface between HUB and SynLink PDU Controller. Connect this port to a SynLink PDU’s sensor port using a standard network cable (straight-through). An 8 foot network cable is included in the package.
Setup
Step 1
Reference the wiring examples for connecting sensors and actuators.
Step 2
Plug the HUB into the wall using the provided power brick.
Step 3
Using a standard network cable (straight-through), establish a connection from the Sensor Port of the HUB to any of the Sensor Ports on the SynLink PDU.
Step 4
Once connected, the SynLink PDU will promptly detect the HUB, making it instantly accessible for use.
