The Clock IoT Device is needed for various interfaces to devices or systems in your local network. The role of the Clock IoT Device is to create a "bridge" between the systems in your local network and Clock PMS+ API servers.


The Clock IoT device is powered by a Raspberry Pi or A20-OLinuXino-LIME2 mini-computer that comes with preinstalled state-of-the-art system software developed by Clock. This special software enables the above-mentioned bridge to devices and software, installed in your local area network.


The Clock IoT device bundle includes:

  • Raspberry Pi or A20-OLinuXino-LIME2 mini computer;
  • Clock's system software license
  • SD card with an encryption key
  • Preload of the specific services to be connected. Additional services can be installed remotely
  • Association with the respective Clock PMS+ or Clock POS account;

Clock IoT Device is designed with strong security in mind.


Two types of devices are available:

Clock IoT type A (Raspberry Pi)Clock IoT type B (A20-OLinuXino-LIME2)


Network/Firewall

The Clock IoT device requires constant OUTBOUND (outgoing) access to:
  • *.clock-software.com. TCP ports: 80, 443, 22.
  • *.amazonaws.com. TCP ports: 443, 8443, 8883.
  • ruby-gems.clock-software.com. TCP port 5000
  • UDP port 123 (NTP - Network Time Protocol)
  • Clock does not provide IP ranges as they are subject to change at any moment.
  • Your local network should be different from 172.17.xxx.xxx (or 172.17.0-255.0-255)
  • Clock IoT doesn't need any inbound (incoming) connections/open ports.
  • The Clock IoT Device requires DHCP in the network to automatically obtain its IP address. Fixed IP addresses are not supported.
  • Keep in mind that Clock IoT device need to be placed in the same network as the third party device/system subject to the interface (for TCP/IP protocols) or physically near to the device/system (for USB cabled interfaces). Check each interface for the specific protocol/port requirements.
Important: A Clock IoT device can be connected to only one Clock PMS+ or Clock POS account.

Device/Installation

  • The Clock IoT device requires an Ethernet cable (not included) and power adapter (included). A Wi-Fi connection is not supported.
  • The Clock IoT device should be constantly ON. The usage of an uninterruptible power supply (UPS) is recommended. Restarting the device is strongly NOT recommended, as this may lead to device bricking.
  • Device LEDs. The green LED light (power) should be steady. The yellow LED light (SD card read/write) may blink or be steady.

Checking connections/ports

  • Contact your system administrator and find the IP address of the Clock IoT Device. The device hostname of Clock IoT Device is "clockrpi-" followed by the serial number of the device.
    Example: "clockrpi-a02082-000000006ecb6e0b".

    Successful connection test:

  • Open a browser and enter the device IP address.
  • The Diagnostics page will be opened
  • Please contact the system administration if any of the checks is marked as Failed and ask them to re-check the above "Network / Firewall" section.
