Activation of the radio signal performs automati-
cally, as soon as the function "pulse enabled" is
activated and the EDC module scans 30 pulses
from the register. The current status of the roller
counter is programmable by means of the opti-
cal head using the front-mounted optical interface
of the EDC module. A ZENNER PC-software is
required for programming. The configuration is
made by means of a ZENNER software, the uni-
versal interface MinoConnect and the specific
ZENNER infrared optohead IrCombiHead.
