6-14-7 EDACS TRUNKING MANUAL TEST-REPEATER SIMULATOR
Entering the Repeater Simulator causes the COM-120C to perform an FM-Zero
operation to adjust the Receiver’s DC offset to zero. The screen displays the message:
“Doing FMZ...please wait”.
While in the Repeater Simulator and the Radio is not transmitting, or the repeater is not
calling the Radio, the Site ID message is continuously transmitting. In this idle mode,
the Repeater Simulator is looking for a Call (or Login) request from the Radio. When
the request is found, the Repeater Simulator allows the Radio to transmit (until the
Radio releases). The Group/Logical ID’s are captured (and displayed) when the Group
Call is made (and used to call a Radio). A Radio’s Login is also decoded by the
simulator and the ID’s captured. There is also a mode of operation (activated by
softkey) where the repeater simulates a Radio calling the Radio Under Test. In this
mode, there are softkeys to disconnect and return back to the idle state.
1. CH#:
This field is used to change the
EDACS Repeater Simulator
Working Channel, as specified
by the Channel Number pre-
programmed in the Setup
Screen. Value range: 1 to 20.
The corresponding RF
Frequencies are shown in the
RF fields as the CH# field is
edited. This only sets the
Working Channel. The Control
Channel is taken from the
Setup Screen and must be
changed there if necessary.
If the Band field is set to
‘Manual’ there is no channel
number to edit. The PRGM Soft Function Key F3 may then be used to return to
the channel Band mode.
2. Band:
This field shows the channel format for the Repeater Simulator Working Channel.
Valid values are: 800 MHz, 900 MHz, USER or Manual. Display-only field. If
‘Manual’ is displayed, the RF Frequencies have been set manually in the Repeater
Simulator. All other values are taken from the pre-programmed logical channels
from the Setup Screen, according to the channel number set in the CH# field.
