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
Connector)".
3 Press [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 signal 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, press
[ ] again to turn the transceiver power ( ) ON.
The output signals for each configuration behaves as
follows:
COM Terminal on the
rear panel
PC
CTS/ RTS
(Default)
TxD → RxD
RxD ← TxD
RTS → CTS
CTS ← RTS
GND GND
MSQ/ PKS
No function → RxD
No function ← TxD
MSQ → CTS
PKS ← RTS
GND GND
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.
