A Busterminal is a very simple repeater that consumes +90 mA power supply from the DB9 connector of the attached device (5V from pin 5 and 6). Lots of devices cannot exceed 10 mA, because the power supply on the DB9 is initially implemented to solely provide power to an external termination (even with certified devices). Please check the manual of the Busterminal. It should contain a list of devices that can be used with this product. Of course, these are only the devices from this manufacturer.
