Connecting your shop to Flow

Everything your IT person, or you, needs to connect the machines and terminals. One page, no special hardware.

01

How it connects

Each machine control sends data over your shop network to the Flow gateway. The gateway sends it to Flow over one outbound, encrypted connection. Nothing on the internet can connect into your shop.

  1. Machine control
  2. Flow gateway
  3. Flow cloud

What the Flow gateway is

Software you install on a PC on your shop network. From it you add machines, set each machine’s IP address, and connect other hardware Flow uses, such as label printers that print a label for each job.

Sign in to your Flow account online, download the gateway, then add your machines and printers in it.

02

What you need on the floor

ItemRequirement
Machine networkA wired Ethernet drop to each machine control, on the same network as the gateway
Flow gatewaySoftware installed on one PC per shop, wired to the same switch as the machines. Manages machines, their IP addresses and label printers
TerminalsA tablet or touchscreen at each machine, on shop Wi-Fi or wired
InternetAny business connection. About 1 GB of data a month for every 10 machines
03

IP addresses

Give each machine control and the gateway a fixed address, either set on the device or reserved in your router. We recommend putting machines on their own VLAN, separate from office computers.

04

Firewall

Allow the Flow gateway through your firewall so it can communicate with the Flow platform and with your machines.

05

Before the install

  • A list of machines with model and year
  • An Ethernet drop at each machine
  • A fixed IP address for each control and the gateway
  • The Flow gateway allowed through your firewall
