The device does not contain an IR sender. You have to connect one such 
at one of the 3.5mm plugs at the back end. Something like this:
http://www.smarthome.com/calrad-92-152-single-ir-flashing-emitter.html 
(Possibly there was one in the packing?)

The device (with connected senders) thus contains 2 transmitters that 
can be operated by set_transmitters. But the driver does not implement 
ioctl LIRC_SET_TRANSMITTER_MASK correctly, so this number "2" is never 
reported.

BTW, the just released version of IrScrutinizer (1.3) can read and write 
(assuming connected IR sender!) from this device directly.

Greetz,
