Hardware Installation

Materials You Will Need

• Eyedro Flow Meter box contents
• Two (2) #8 (4.2mm) pan head, round head or button head mounting screws (optional – not included)
• Tie wraps (optional – not included)

Tools You Will Need

Install Pulse Cable(s) for Dry Contact Pulse Meters

Eyedro Pulse Meters are intended to interface with the following pulse meter output formats:

• Form A (KY) dry contact pulses
• 5V DC wetting value¹
• Rising or falling edge detection (default is rising edge)
• Minimum pulse width is 5ms
• Maximum frequency is 100Hz

¹ A higher wetting value (up to 24V) can be achieved by connecting a separate DC power supply (not provided) to input port C of the Eyedro Pulse Monitor module. The mating connector for port C is a 1.65mm (i.d) x 3.5mm (o.d) x 9mm (length) barrel plug with center pin positive.

1. Connect pulse cable to the output of the pulse meter
   • Black conductor of the pulse cable to the K output of the pulse meter.
   • White conductor of the pulse cable to the Y output of the pulse meter.
2. Optionally, use tape or other label to uniquely identify each sensor at the end of the wire nearest to the connector.
3. Route pulse cable(s) to the Eyedro Pulse Meter.

Mount Eyedro Device

Vertical (wall) Mounting

1. Write down the 8-digit serial number from the back of the module. This will be required during software setup.
   • The serial number will be in the format “123 – 45678“
2. Find a clear area on the wall or surface to mount the device.
   • Make sure all cables will easily reach the module before securing.
3. Mark locations on the wall for the screws using the module as a template.
4. If preferred, drill a pilot hole in the marked locations using a 2.5 mm (7/64″) drill bit.
5. Drive the two (2) pan head screws into the wall surface through the flange holes on the sides of the enclosure.
6. Carefully tighten the screws until snug. Do not overtighten or it may cause damage to the flange(s).
7. Ensure secure fit.

Horizontal (surface) Mounting

Mounting is not required for horizontal installations (i.e., on a desktop or shelf). If added security is desired, follow instructions for vertical mounting using screws or double-sided tape.

Connect Cabling

Important

• Ensure all connectors and sockets are free from damage prior to mating them.
• Ensure the retention clip on the Ethernet cable is intact.
• Never force connectors.
• Never apply levering action while connecting or disconnecting.
• Always grasp connectors by the strain relief while connecting or disconnecting.
• Ensure all connections are secure.

Dry Contact (KY) Pulse Meters

1. Connect the pulse cable(s) to the sensor input ports (A or B) of the Eyedro Pulse Meter.
   • NOTE: The mating connector for the sensors are 1.3mm (i.d.) X 3.5mm (o.d.) X 9mm (length) barrel plug.
2. Optionally, connect the wetting voltage power supply to obtain a wetting voltage greater than 5V DC – not included.
3. For devices that will connect to the internet via Ethernet, connect one end of Ethernet cable to Eyedro module.
4. For devices that will connect to the internet via Ethernet, connect the other end of the Ethernet cable to the router (or Internet access point).Connect the appropriate end of the low-voltage power adapter to the Eyedro module.
5. Connect the appropriate end of the low-voltage power adapter to the Eyedro module.
   • Pulse monitoring devices use a power supply with a 5V DC output.
6. Plug the other end of the low-voltage power adapter into a nearby AC wall receptacle.
7. Optionally, secure all wiring neatly with tie wraps (not included).

Dry Contact (KY) Pulse Meters Optional – Increased Wetting Value (>5VDC)

1. Connect the appropriate end of the wetting voltage DC power adapter (24V DC max – not included) to port C of the Eyedro Pulse Meter.
   • IMPORTANT: The mating connector for port C is a 1.65mm (i.d) x 3.5mm (o.d) x 9mm (length) barrel plug with center pin positive.
2. Plug the other end of the wetting voltage DC power adapter into a nearby AC wall receptacle.
