Pin 13: TXDI
[Digital Input for DATA Communications]
 TX Hi-speed Data Input Type (jumper JP2005).
Input level 800 mV/600 Ohms, Max.input 1.2V
 Tx Low-speed Data input Type ( Jumper
JP2006). Input level 40 mV/600-Ohms
If the Jumper setting is "Low-speed Data" (JP2006
jumpered), this port is usable in the AUDIO
(300~3000 Hz) range.
If the jumper setting is "HI-speed Data" (JP2005
jumpered), this port is usable for 9600 bps DATA
communications, because the filter and limiter are
not engaged in the Audio line.
Pin 14: DC OUT
[13.4 V/5 V DC Output]
 Switched 13.8V output for supplying power to
an accessory (jumper JP2008).
 Switched and regulated DC 5.0V output for
supplying power to an accessory (jumper
JP2007).
Maximum output current is 200 mA
Pin 15: IGN
[Ignition Sense feature]
Connecting this line to the ignition sense line of
the vehicle will automatically turn the radio on
when the vehicle's ignition key is turned on.
Pin 16: NC
[NO connection]
Pin 17: RX DO
[Digital Output for DATA Communications]
 RX Hi-speed Data Output Type (jumper
JP2003). output level 600 mV/10k Ohms
 RX Low-speed Data Output Type (jumper
JP2004). output level 200 mV/600 Ohms
If the Jumper setting is "Low-speed Data" (JP2004
jumpered), this port is usable in the AUDIO
(300~3000 Hz) range.
If the jumper setting is "HI-speed Data" (JP2003
jumpered), this port is usable for 9600 bps DATA
communications, because the filter and limiter are
not engaged in the Audio line.

DSUB 25-Pin Accessory Connector
Pin 18: E
[GND]
Ground for all logic levels and power supply re-
turn.
Pins 19, 20, 21, & 22: DSUB 19, DSUB 20, DSUB 21
and DSUB 22
LOGIC level (+5V / 0V) output.
The logic output appears at these pins when the
front panel's PF key is turned on.
The possible programming features (use CE49)
are illustrated below.
If the HA feature is assigned to these ports, a cur-
rent amplifier must be connected between the
Horn circuit and the port.
None/A PORT/B PORT/C PORT/D PORT/E
PORT/HA PORT
Pin 23: EXT SQL
Open collector output. Max. sink current 10 mA.
A Signal is present (Squelch is open): Level High
No Signal is present (Squelch is closed): Open
When you connect the solder jumper on J2002,
this port changes to PULL UP (5 V) output.
This status can be changed by CE49 programmer.
Pin 24: SP MUTE
Open collector output.
External Speaker mute on: Level High
External Speaker mute off: Open
Pin 25: E
[GND]
Chassis ground.
