Safety notices
Every effort has been made to make this manual correct and up to date. Due to continuous
development of the product and by error or omission, anomalies may be found and this is
acknowledged.

Level of risk
As the SR2200 is powered from 12V DC, there is little chance of serious injury as long as
common sense is applied.
DC input is a nominal 12V DC wired center positive. Reverse polarity connection will damage the
SR2200 and potentially could lead to the risk of fire or explosion under severe circumstances.
NEVER connect the SR2200 directly to an AC outlet.
Handling the SR2200
Use a soft, dry cloth to gently wipe the SR2200 clean, never use abrasive cleaners or organic
solvents which may damage certain parts. Treat the unit with care, avoid spillage or leakage of
liquids into the cabinet. Special care should be taken to avoid liquid entering via the connection
sockets.
Special remarks
Do not use or leave the SR2200 in direct sunlight. It is best to avoid locations where excessive
heat, humidity, dust and vibration are expected. Always keep the SR2200 free from dust and
moisture.
Other warnings
There are no internal operator adjustments. In the unlikely event of servicing being required,
please contact your dealer for technical assistance.
Although carefully designed, the SR2200 (like all receivers) suffers from a degree of internal
noises known as spurii. They are a product of the receiver circuitry and do not represent a fault.
The reception might be affected by interferences produced by nearby electrical appliances such
as television, PC, walkie-talkies, etc... The reception might be strongly affected by powerful
transmissions if the receiver or the antenna is located nearby a transmitter (such as TV
broadcasting transmitter).
Transmissions with encrypted content cannot be decoded by this receiver.
Specification is typical but not guaranteed, subject to change without notice due to continuous
development of the product.

SUPPLIED ACCESSORIES
• DC power cable
• Operating manual
• Basic control software for testing purposes, on CD. This software does not support USB
connections, only RS-232C. If your PC (particularly laptops) does not feature a RS232C
port, you may alternatively use a “USB to SERIA ” adapter. This software is supplied “as
is” without any guarantee of any kind.
• Complete command list (inside the manual)
• USB driver on CD.

Refer to this diagram for connection details:
① 10.7MHz IF OUT with +/- 5MHz of bandwidth.
② Headphone socket (3.5mm mono jack, also wired for stereo plug). When this socket is
used, any external speaker connected to socket (3) will be automatically disconnected.
③ External speaker socket (3.5mm mono). The speaker should have a nominal 8 Ω
impedance and power handling of 2 Watts or greater.
④ Accessory socket. Provides output for audio and discriminator, or other applications you
might create. Pin allocation as follows:
Values for pins 2, 6, 7 are for a 3kHz FM deviation at antenna input level.

⑤ RS-232C socket for PC control. The connection cable is not supplied..
⑥ USB socket for PC control. The connection cable is not supplied.
When you connect the SR2200 (power ON) to the PC for the first time, Windows will detect
the USB connection and ask you for a driver. At this time insert the supplied CD and find
the folder named “USB DRIVER”. Driver installation will be automatic.
Please note that the supplied SR2200 control software does not function with a USB
connection. You may use the Windows “Hyper Terminal” software which is supporting USB
connections.
⑦ 12V DC input socket. The DC power cable is supplied. Please connect it to a power unit
providing 12 to 16V DC, with minimum 0.5 A. Center pin is positive.
⑧ Power switch and power ED. Unit is powered and the green ED is lit, when the switch is
in the upper position.
⑨ Antenna socket. BNC type. Preferably use an antenna with coaxial lead matched to 50Ω,
for optimal performance.
⑩ Remote control panel. The optional control panel head (with internal speaker), similar to
the control panel of AR-ONE is used to test functionality of the receiver, when a PC is not
available.

CO TROL COMMA DS FOR TERMI AL SOFTWARE
The SR2200 is operated via PC using the RS232C, or USB port. The commands necessary to
that effect, are described in this chapter.
Microsoft Windows Hyper Terminal may be used to control the SR2200, or you may use your own
software by integrating the following commands.
Communication parameters
• Baud rate 38400 BPS
• Data length 8 bits - ^A nn [cr],[ F]  ^A = 13 Hex  nn = Receiver's ID #
• Stop bit 1 bits If ID # = 00 (DEFAU T VA UE), command can be input directly.
• Parity NONE
• Flow control NONE
• ocal echo ON (set in ASCII settings of Microsoft HYPERTERMINA )
Delimiter
■PC → SR2200
<CR> （0x0d）
or
<CR>< F> （0x0d 0x0a）
Note: < F> will be ignored
■SR2200 → PC
• “OK”response when the command has been correct:
<SP><CR>< F>（0x20 0x0d 0x0a）
• Response when the command has been incorrect:
？<CR>< F> （0x3f 0x0d 0x0a）
• Response to the read command:
Following the output of the parameter, the correct response should read:
<SP><CR>< F>（0x20 0x0d 0x0a）
umerical parameter auto-correct
The SR2200 does correct the numerical command parameter to the digit format applying to the
given parameter. In the following example, the DB command has to be followed by a 3-digit
number.
Ex.: DB003 <CR>
The SR2200 will add one or two “0” in order to achieve three digits.

DB3<CR> ......... processed as DB003<CR>
DB03<CR> ....... processed as DB003<CR>
However be aware that for some commands like Memory Channel or Search Bank, if you input
MQ33 for MQ303 (bank 3, channel 3), the SR2000 would mistakenly correct your entry to MQ033
which means bank 0, channel 33.

USI G THE SUPPLIED “
““
“SR2200 CO TROL SOFTWARE”
””
”
The software is supplied "as is" for testing purposes, with no warranty nor formal support.
The “SR2200 CONTRO SOFTWARE” only recognizes the receiver’s RS232C connector.
If your PC (particularly laptops) does not feature a RS232C port, you may alternatively use a
“USB to SERIA ” adapter.
System requirements:
• IBM PC compatible receiver with an available RS232C port.
• Microsoft® Windows® 98 up to Vista (32 bit). 64bit systems not supported.
• Pentium® 300MHz processor or faster
• RAM and hard disk space requirements are negligible.
① Connect the SR2200 to your PC using a serial cable. Make sure that you have powered on
the SR2200.
In case you would like to use a “USB to serial” adapter, install this adapter first as specified by
the manufacturer’s instructions.
② Install and launch the control software. The main control window looks like this:
The default COM PORT 1 setting
should allow you to control your
receiver right away. Depending on you
PC’s configuration, the COM PORT to
which you connected the SR2200 can
be different from COM1. In this case it
is necessary to select the appropriate
number as pictured on the right.

When using a “USB to serial” adapter, the COM number Windows automatically assigns can be
quite high, such as 5 to 8. You will need to select the correct COM port, as pictured. It is possible
that you then may have to close the program and to start it again, for the connection to be
recognized.
Please make sure that the RS232C port speed is set at 38400 bps and not 19200 bps, otherwise
the connection with the PC will fail. Access this option by selecting COM > Speed and then select
“38400 bps”.
HOW TO I PUT A FREQUE CY
① First select the VFO (VFO A to J) in which the frequency will be stored. If the VFO already
contains a frequency, then the receiver will be tuned to it.
② Click the “Freq.Input” button:

The following window will appear:
③ Input the desired frequency in the left frame and click OK. If other frequencies have been
stored previously in other VFO’s, you may select one in the right window, transfer it to the left
window by clicking on the <= arrow, and validate with OK.
OTHER FU CTIO S
① Reception Modes: You have to manually choose between:
AM (Amplitude Modulation). IF filter bandwidth of 6 kHz.
NFM (Narrow Band Frequency Modulation): IF filter bandwidth of 15kHz.
WFM (Wide Band Frequency Modulation): IF filter bandwidth of 15kHz.
SFM (Super Narrow Frequency Modulation): IF filter bandwidth of 6kHz.
