TUSB-485 : USB to RS-485 Dongle
USB to RS-485 interface dongle, for connecting an RS-485 device to a PC's USB port.
Overview
The TUSB-485 is a USB to RS-485 interface dongle, for connecting an RS-485 device to a PC that only has USB ports - most laptops and modern desktops have no native RS-485 port, so a converter like this sits between the two.
The obvious pairing in this catalogue is the Tstep-087-485 stepper drive, which takes its commands over RS-485 rather than step/direction pulses; configuring it, or running it in bus-controlled mode from a PC instead of a PLC, needs an RS-485 connection the PC doesn't have natively. The TUSB-485 provides that connection without needing a PLC or a dedicated RS-485 card in the PC.
It draws power from the USB port itself, so no separate power supply is needed for the dongle - only for whatever RS-485 device is on the other end.
Beyond stepper drives, the same dongle works with any RS-485 device needing a USB-connected host, such as this catalogue's own TIO-0808 RS-485 I/O module.

Questions
My laptop doesn't have an RS-485 port — will this let me connect a stepper drive like the Tstep-087-485 to it?
Yes, that's the obvious pairing — the Tstep-087-485 takes its commands over RS-485 rather than step/direction pulses, and most laptops and modern desktops have no native RS-485 port, so this sits between the two.
Do I need a PLC to run or configure an RS-485 drive from my PC, or will this cover it?
This covers it — no PLC or dedicated RS-485 card in the PC needed, just this dongle and a USB port.
Does it need its own power supply?
No, it draws power from the USB port itself — the only thing that needs its own supply is whatever RS-485 device is on the other end.
Is this only meant for your stepper drives, or does it work with other RS-485 devices?
Any RS-485 device needing a USB-connected host works with it — this catalogue's own TIO-0808 I/O module is another example.
