Function
P1-24
/PWR_EVAL
OUT
Power on Monitor output:
GT6201 “OFF” - open circuit GT6201 on -
closed circuit to GND (max. 100 mA)
This output indicates if the transceiver is switched on or switched off. It is an open collector output
type. The output is internally connected to ground when the unit is switched on. In this case a
current of maximum 100 mA can flow into the transceiver to drive for example an external relay.
The output has high impedance when the unit is switched off.
Note:
In order to avoid damage of this output
, a protection diode
parallel to the external
relay shall
be connected.
VHF Channel Signal Indication (/SQL_EVAL)
Pin No.
Pin Name
Direction
Function
J1-4
/SQL_EVAL
OUT
Indicates presence of the VHF channel’s
signal on the audio outputs.
This output indicates presence of the VHF channel’s signal on the audio outputs. It is an open
collector output type. The output is internally connected to the ground when the unit receives signal
on the selected VHF channel. This audio signal is available on audio outputs. In this case a current
of maximum 100 mA can flow into the transceiver to drive an external relay for example. The output
has high impedance when the unit is switched off.
External Mike Switch (/MIKE_SW)
Pin No.

Function
J1-24
/MIKE_SW
IN
Configuration selector CFG1 and CFG2.
ACTIVE state - closed contact to GND
The external Mike switch provides selection between the two available audio in/out configurations:
CFG1 and CFG2. Configurations can also be switched during operation in installation setup.
•
When /MIKE_SW is active then configuration CFG1 is used.
•
When /MIKE_SW is inactive then CFG2 is used.
Each configuration CFG1 and CFG2 stores several parameters that can be set in installation setup
pages. (For details refer to chapter 2.7).
2.5
Installation
and Configuration of
GT6201 Transceivers
Connection to the following equipment is required as minimum for GT6201 VHF transceivers:
•
Power supply
•
Antenna
•
Microphone (direct or via external audio panel)
•
Headphone or speaker (direct or via external audio panel)
•
Push-To-Talk (PTT) switch
Note:
1.
Use only
qualified
cables (
self-
extinguishing).
2.
Use AWG 20 for power supply and AWG 22/24 for other cables.
3.
Fit sleeves over the solder joints on the equipment connector. Crimp
connectors are also available from B
ECKER
.
4.
Protect the power supply with a 7.5
A fuse.
