Operating Manual Reprint
Similarly, if you assign “CH SW0,” “CH SW1,”
and “CH SW2” to the Universal Input Port, you
can recall Channels 1~7 as shown below:
The Memory Channel is determined via the CE49
Programmer. (Common ➠ DSUB-25pin connec-
tor ➠ Channel switch Table).
If you need to recall all memory channels (15 CH)
from the External Controller via the Uni-versal
Input Port, you should assign the “All Channel
Recall” Command (CH SW 0 ~ CH SW 3) to the
Universal Input Port.
In this case:
Channel CH SW0 CH SW1 CH SW2

Sample Circuit
Pin 7: E
[GND]
Ground for all logic levels and power supply re-
turn.
Pin 8: A KEY OUT [Universal Output Port]
Open collector output. Output voltage 0 ~ 5 V,
Max. sink current 30 mA.
The possible programming features (use CE49)
are illustrated below.
A PORT/B PORT/C PORT/D PORT/E PORT/
None
Refer to the “Pins 20, 21, & 22” section for details.
Pin 9: TXD
[Digital Output for Alignment software]
Connect to the RS232C cable (requires FIF-8 and
CT-88)
Pin 10: RXD
[Digital Input for Alignment software]
Connect to the RS232C cable (requires FIF-8 and
CT-88)
Pin 11: EXT PTT
Shorting this port to ground causes the transceiver
to be placed in the Transmit mode, while open-
ing the connection to this port returns the trans-
ceiver to the Receive mode.
Pin 12: MIC MUTE
MIC mute on: Level High (5V)
MIC mute off: Open
LOGIC level (+5V / 0V) output.
When the PTT/EXT PTT switch is pressed, this
pin switches to “open.”
