Installation:
Programming the Consolette
9.
Dekey the Consolette by deactivating the APCO PTT signal.
10. On the Audio Parameters page of the Configuration Application, restore Wireline Function to
the previous or desired value, then click the “Store” button.
3.7.3.2 Remote Control via ACIM Setup
The Consolette can be remotely controlled from a Console supporting the RS232-based ACIM port.
Refer to
section 4.12.3
for more details on this operation. In the Audio Parameters Page (
Figure 3-
9
), first enable the ACIM interface on the Consolette by selecting “ACIM” under the “Wireline
Function” section. The user can also configure the unit for 2-wire or 4-wire operation and 600-ohm or
High Impedance from the Remote Interface Parameters Page (
Figure 3-10
and
Figure 3-11
).
Reporting of the MDC-1200 IDs can be enabled on this page as well.
NOTE:
Some systems utilize external MDC-1200 decoders and prefer to have this field disabled.
Also refer to
section 3.7.3.4.13
(Transmit Priority Operation). It is recommend for Remote Control via
ACIM that Wireline is set as the priority input.
3.7.3.3 Remote Control via E&M Setup
The Consolette supports a PTT input (PTT*) on its rear panel. The associated audio path for this
PTT input is defaulted to the single ended audio signal (AUX_TX) located on the DB25 connector on
the Consolette rear panel. To instead use the balanced wireline audio path with this PTT input, select
“Hardware PTT” for the “Wireline Function” in the Audio Parameters Page (
Figure 3-9
) and set the
“TRC AGC Configuration” to “Disabled” in the Remote Interface Parameters Page (
Figure 3-10
and
Figure 3-11
). The user can also set up the wireline for 2-wire or 4-wire operation, and 600-ohm or
High Impedance operation from this page.
Also refer to
section 3.7.3.4.13
(Transmit Priority Operation). It is recommend for Remote Control via
E&M that Wireline is set as the priority input.
3.7.3.3.1 Transmit Audio Tuning - AUX_TX
The Consolette ships from the factory with the “Crosspatch In (TX) Gain Setting” at a nominal -6
dBm. This gain is user adjustable from the Gain Adjustments Page (
Figure 3-13
).
To adjust the transmit tuning of the AUX_TX path on the Consolette, first make sure that the
“Crosspatch-Hardware PTT Selection” located in the Audio Parameters Page (
Figure 3-9
) is set to
“Hardware PTT (Aux Tx)”. Next, generate a 1 kHz signal at 300mVrms from a 600 Ohm source into
AUX_TX while asserting the PTT* signal. Measure the deviation of the received RF signal. Adjust
the “Crosspatch In (TX) Gain Setting” field to increase or decrease the corresponding gain, then hit
“apply” to see the result. Continue to adjust as necessary by selecting the up arrow or the down
arrow and selecting the “apply” button. Once you have obtained the final setting, then hit “Store” at
the bottom of the page to commit the new gains to the Consolette codeplug.
3.7.3.3.2 Receive Audio Tuning - RX_AUDIO
The Consolette ships from the factory with the "RX Codec Adjustment" set at a nominal 4 dBm. This
gain is user adjustable from the Gain Adjustments Page (
Figure 3-13
).
To adjust the receive tuning of the RX_AUDIO path on the Consolette, first generate an on-
frequency signal modulated with a 1 kHz tone at 60% rated system deviation. See the table below for
the deviation levels for each channel spacing:
