SWITCHING THE COM CONNECTOR PIN
ARRANGEMENT
You can configure the RTS/CTS terminals of the
COM
connector on the rear panel allowing it to function in the
same manner as the MSQ/PKS terminals of the
ACC 2
connector.
[
]
[F1]~[F7]
[MENU]
F[ADV.]
1
Press
[ADV.]
(F) from the
Menu
screen to open the
Advanced Menu
screen.
2
Access Menu 24, "MSQ/PKS Pin Assignment (COM

[SELECT]
(F4) to allow editing of the parameter
box.
4
Press
[-]
(F4) or
[+]
(F5) to select "On" or "Off" to
determine the pin behavior.
The default is "Off".
Off: The COM connector is normal (CTS/RTS mode).
The
COM
connector processes the RTS signal and CTS
signal.
On: The COM connector is in MSQ/PKS mode.
The signals on the RTS and CTS pins of the
COM
connector
are replaced with the MSQ and PKS signals, respectively.
A message confirming the
COM
connector behavior appears.
5
Press
[OK]
(F4).
6
Press
[
]
(F1).
7
Press
[MENU]
to exit.
8
Press
[

to turn the transceiver power (
) OFF, then
press
[

Note:
◆
The revised configurations cannot be enabled until the transceiver
is restarted.
◆
If "On" is configured for the MSQ/PKS Pin Assignment, you cannot
control the transceiver using the ARCP-990 and ARHP-990 or by
PC commands sent via the
COM
connector.
◆
If "Off" is configured for the MSQ/PKS Pin Assignment, the
transceiver transmits when the PKS pin of the
ACC 2
connector is
shorted to GND.
◆
The I/O level of the audio varies depending on the sound device
connected. If the audio I/O level does not match the transceiver,
use Menus 7-06, 7-10, and 7-11 to change the audio I/O level on
the
ACC 2
connector.
{page 16-20}
◆
The squelch signal of the sub band cannot be transferred.
