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 à DSUB-25pin connec-

tor à 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:

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 trans-

ceiver to be placed in the Transmit mode, while

opening the connection to this port returns the

transceiver 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.”
