External antennas DECT™antennas, impedance
50 Ohm, VSWR ≤ 2.0 When connecting external
antennas, the HF connection
is automatically switched
over to the external
antennas.
Input contact Open-circuit voltage: 4V DC
Short-circuit current: ≤ 1mA
(separation by opto-couplers
and isolated power supply)
– For use at the customer's
discretion.
– Can be parametrized as
normally closed or normally
open contact.
– The maximum allowed line
connection resistance
between the external
switch and the contact
input is 100 Ohm.
Operating mode
LED – Green flashing --> Device
ready, no active DECT
connection
– Green --> Device ready, at
least one active DECT
connection
– Yellow flashing --> Device
ready, no active DECT
connection, base station
„Out of Sync.“
– Yellow --> Device ready, at
least one active DECT
connection, base station
„Out of Sync.“
– Red --> Device is online;
connection established to a
DECT™controller,
– Red flashing --> Device is
offline; no connection
established to a
DECT™controller, fault
– Red flashing fast --> Device
is offline; firmware update
is busy
– During the switching-on
process (boot loader
