Peltor DECT-Com configuration

Its possible to adjust RX/TX level and VOX level of Peltor base unit by PC tool via serial connection(SERIO). The SERIO kit from Peltor was not available and was not tested. Probably if it is possible to change TX level of DECT-Com from default 245 mV to 1V, no soldering on IP21 is needed and pin 1(TX output) of Peltor can be connected directly to pin 11 of IP21 DOOR interface.
