4-3-2 Example set-up for the ICOM IC-R8500 receiver

Set the R8500 by accessing the ICOM initial set mode as per page 30 of the ICOM operating manual.
Set the baud rate to 9600 and address to 4Ah. No interface is required.
The receiver must be configured and switched On before the SDU5500 in order to provide a valid
connection via the RS232.
Note: The output level of the ICOM receiver(s) is about 10 - 15dB below that of the AOR receiver(s)
and may be more liable to AGC effect as signals reach the centre of companion radio passband.
•
Connect a suitable power supply to the SDU5500 using the d.c. lead provided. Ensure the correct
polarity is observed, the stripe signifies positive. (In certain market areas, a suitable power supply may
be provided).
•
When using an IC-R8500, connect an RS232 lead between the receiver and RX CTR socket of the
SDU5500 (see section 2-2 item 2 of this manual for pin-out information). If using the IC-R7100 or
IC-R9000, connect and power the optional ICOM CT17 interface.
•
Connect a 50 OHM patch lead between the RF IN socket of the SDU5500 and the IF OUT socket of
the receiver (ICOM use a phono socket, the input of the SDU5500 uses a BNC).
Cold start
It is important that the companion radio is switched on FIRST.
Now switch on the SDU5500. The first time the SDU5500 is switched on, or whenever power is
removed from the SDU5500, a COLD START sequence needs to be followed. This involves selecting
the required companion radio via the SDU5500 configuration menu. As long as power is not removed
from the SDU5500 (even though it may be switched off with power still connected), the SDU5500 will
remember which companion radio is in use.
Note: The SDU5500 CPU draws a very small current for backup purposes even though the
SDU5500 power switch is off.
The SDU5500 LCD will display various details. Under the item "RX" (third line down from the top left of
the LCD), the ICOM radio type will be displayed. Ensure that menu item "1" is displayed in the lower
left corner of the LCD, if not use the PREV (previous) and NEXT keys. Press RX to display the
companion radio configuration menu.
