Example:
2.5.3.2 Connecting the USB interface cable
1. Attach the locking wire saddle at the location shown in the figure below.
2. Put the USB cable through the locking wire saddle as shown in the figure below.
Note:
Putting the USB cable through the locking wire saddle, as shown in the figure below, prevents the
cable from coming unplugged.
3. Connect the USB cable from the host computer to the USB upstream connector.
4. Up to 2 USB devices can be connected to a USB model TM-T88IV by using 2 USB
downstream connectors.
Note:
The hub installed in a USB model connector panel is a bus-power-supply hub. It is important to note
that bus-power-supply hubs (including other USB model TM printers) and bus-power-supply
functions with a current consumption of 100 mA or more cannot be connected directly to the printer.
