COS Enable:
By enabling the COS output feature (Pin 17
of the Accessory Connector) you can customize how COS
output will operate. The COS output can be made to
toggle when carrier is present on the receiver or when
valid signaling is determined. The polarity of the output
is selectable to meet the needs of the external peripheral.
If the COS is disabled, Pin 17 defaults as a general
purpose I/O that can be controlled remotely.
Cooling FAN Operation:
The cooling fans can be made
to operate continuously or only during transmit.
CSQ Repeat:
Selecting this option will cause the
repeater to repeat every instance of valid carrier. The TX
options transmitted will be that of those programmed in
for Slot 1 of the User Settings.
Tx Timeout:
TX Timeout controls how long the CS-540
will keep the transmitter continuously keyed before the
RF Power Amp (RF PA) is automatically disengaged. The
maximum value of the TX Timeout feature is 999
seconds. To disable the TX Timeout feature, enter 0 in
the TX Timeout field.
Remote Access Code:
The System Operator can
remotely program and manage the CS-540 Community
Repeater by using DTMF tone sequences. (See “Chapter
8: Remote Programming” for more information.) Before
making any modifications, the System Operator must
enter the Remote Access Code to gain access to the
system. The Remote Access Code is a four-digit number
that you specify on a per channel basis. The remote
code “5555” is reserved for remote rebooting, but all
other four-digit numbers are valid. If you want to disable
the Remote Access feature, simply don’t create a user in
the System Operator slot. Without a designated System
Operator, the Remote Access Code is irrelevant. For
more information on the CS-540’s remote programming
features, see “Chapter 8: Remote Programming”.
User Settings
User ID:
The User ID is an eight-character name that
will be displayed in the CS-540’s LCD while that user’s
call is being repeated. Legal characters in the User ID
include uppercase letters, numbers, dashes, and periods.
By default, users are assigned the name “USER” plus a
two digit number corresponding to the slot of that user.
For example, the user in slot #8 will be assigned the
name USER08 by default. The user in slot 0 is assigned
the name “SYS-OP” to reflect its special role as the
System Operator, but you can change its User ID as well
if you prefer.
Status:
Each user has a status of “Active” or “Inactive”.
By default, all users are “Active”. If you mark a user as
“Inactive”, their calls will not repeated, although all their
information will still be retained in the system. This
option is useful if you want to suspend the repeater
privileges of a user, without deleting that user entirely.
RX/TX Signaling:
Each user must be assigned an Rx
Signal and a TX Signal. You may specify either a CTCSS
tone or a DCS code. If you select a CTCSS tone, you
must also specify one of 50 tones ranging from 67.0 to
254.1 Hz. If you select DCS code, you must also specify
one of 112 three-digit codes, inverted or non-inverted.
The Rx Signal and TX Signal are selected separately. The
per user TX signaling setting can also be made to
transmit carrier only (CSQ). The CS-540 is capable of
cross tone/code encoding. For example, if the CS-540
detects that it has received a transmit request with a
179.9 Hz CTCSS tone, it can then repeat the call with a
162.2 Hz CTCSS tone, or even with a DCS code. Cross
tone/code encoding can be useful when setting up
multiple repeaters at different locations that share the
same frequency.
NOTE:
If you employ both DCS and CTCSS RX
squelch options for users on the same channel, we
recommend that you do not use an RX CTCSS tone
of 136.5 Hz for any users on that channel. Some
transmitting mobiles use a DCS turnoff code of
136.5 Hz that the repeater could misinterpret as a
valid incoming call.
Courtesy Tone:
When a user has finished transmitting,
the CS-540 can emit a courtesy tone. The courtesy tone
can be set for 500 Hz, 1000 Hz, 1500 Hz, or no courtesy
tone. The duration of the courtesy tone is fixed at 75
milliseconds.
TX Hold Time:
After a user has finished transmitting,
the repeater can continue to transmit for a programmed
amount of hold time. TX Hold Time has a range of 0 to
65,535 ms. However, during remote programming, the
max number that can entered is 9,999 ms. If the user
has a courtesy tone, it is recommended that you set the
TX Hold Time to be at least 250 ms.
Tone-in-Tail:
Without Tone-in-Tail enabled, the CS-540
will not encode the user’s CTCSS tone or DCS code when
that user has de-keyed, even though the repeater
continues to transmit for the duration of the TX Hold
Time. With Tone-In-Tail enabled, the CS-540 will encode
the user’s CTCSS tone or DCS code during the TX Hold
Time. Whether or not Tone-in-Tail should be enabled or
not depends on the requirements of your system
configuration.
Error Alerts
PLL Lock Error:
The CS-540 supports monitoring the status of the PLL/VCO circuitry in both the Receive and
Transmit modules. In the event the receiver’s PLL is unable to lock due to a hardware failure, the CS-540 will
display RXPLLER. If the transmitter's PLL circuitry should fail, TXPLLER will be displayed. Upon detecting a PLL
error, the CS-540 will enter an error state. While in error state, the CS-540 repeater operation will be
suspended. The user may try to reprogram the channel by pressing the up/down buttons. In the event the
problem is unsolvable, the repeater may require servicing. Please contact your dealer or BridgeCom Systems,
Inc. technical support.
