Overview

Thank you for purchasing the SWL IR Remote. We are confident that you will get many hours of

listening pleasure from your R-5000 using the remote. Don’t hesitate to contact us at

[email protected] if you have any problems or questions. We want your experience

with our products to be as positive and enjoyable as possible. We also appreciate any comments

on how we can make our products better.

The SWL IR Remote is a microcontroller-based device that decodes the Infrared pulse stream

from a Universal Remote control and converts it into the remote commands for shortwave

receivers and transceivers. Several versions of the SWL IR Remote are available for different

models of Receivers and Transceivers.

The SWL IR Remote is connected R-5000 receiver using a 1/8in (3.5 mm) audio type cable with

a 6-pin DIN male connector connected from the SWL IR Remote to the 6-pin DIN ACC port on

the receiver.

Power for the SWL IR Remote is provided by the included wall power supply. Alternatively, 9-

12Volts DC at 100ma max can be supplied to the power connector. The center pin of the coax

power connector is positive. There is a blocking diode in the circuit, so reverse polarity will not

harm the SWL IR Remote control unit. Customers in Europe receive a DC cable that connects to

the coax power jack on the SWL IR Remote control unit and has pig tail leads on the other end

for connecting to a DC power supply.

All keys on the Universal Remote are indicated in this manual with bold type. The keys used for

radio control are the digits 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, Mute, Power, Enter, and Last or Previous.

All references to the Last key also refers to the Previous key on the remotes that have that key.

Any Universal Remote control should operate the SWL IR Remote. Follow the instructions in

the remote manual to set the remote to operate a Sony TV. The remote needs digit keys, Power,

Enter, and Last or Previous buttons. The remote should be in TV mode to operate properly.

Make sure you do not have Cable or VCR modes selected. The codes from the keys when in

Cable or VCR mode are different and will not operate the SWL IR Remote.

None of the settings are changed in the radio with the exception of memories that you write with

the remote. All settings are temporary in the remote control. You can go back at any time to

using your radio from the front panel. Move the AF gain, RF gain, Squelch, and PBT controls

back and forth on the R75 until control is restored when returning to manual operation on the

front panel. Move the BWC and PBS controls on the NRD-535 until front panel control returns.

Keep the Quick Commands Reference sheet by your remote as reference on the SWL IR Remote

operation.

Connection to Radio

Connect the 1/8in (3.5mm) audio type plug on the cable into the back of the SWL IR Remote and

the 6-pin DIN connector on the radio jack marked ACC. You do not need to use an IF-232C

Level Converter with the SWL IR Remote. The baud rate is fixed at 4800 and cannot be

changed.

Plug in the wall power supply and plug into the back of the SWL IR Remote control box. The

power connector is located on the back left hand side of the control unit. The SWL IR Remote

draws very little power and does not include or need a power switch.

Note: Included is an IC-10 kit that must be installed in the R-5000 for the SWL IR Remote to

work properly. This kit provides the serial interface to the radio. Included is an instruction sheet

to install the IC-10 kit in your radio. You will have to disassemble the radio to install these two

ICs. Be sure to install the ICs with pin one in the proper direction. Contact us if you need help

installing these chips.

Note: The power button on the R-5000 must be pushed in for the SWL IR Remote to work

properly. Once the power button is pressed in, you can use the remote to power the radio on and

off.

Level Converter Option

Plug the DB9 cable from your computer into the back of the SWL IR Remote if you have the

SWL IR Remote version with the Level Converter option. The baud rate for the Level Converter

option is fixed at 4800 baud and cannot be changed.

Remote Control Operation

Description

The following describes the operation of the remote control. Refer to the Universal Remote

Commands tables, or the Commands Quick Reference guides for specific features on different

radios.

Once you begin to use the remote you will get very comfortable with the operation. There is a lot

of functionality achieved by just a few remote buttons. You can stick with the basic operations of

the remote (volume, frequency, and memory) and still achieve a lot of control over your radio.

The biggest problem you will have in the operation of the remote is the Enter key. If you do not

enter the codes exactly you will end up trying to enter a direct frequency. Direct frequency entry

can occur in either VFO or memory modes.

Power

When the radio is turned off with the remote, certain status is saved to non-volatile memory and

restored when power is turned back on with the remote. The current memory selection, current

tuning step, and the VFO/memory mode are stored in non-volatile memory. The last frequency

entered is kept in volatile memory and will be lost when power is removed from the control unit.

Direct Frequency Entry

When entering frequencies directly, be sure to press a digit key before the first decimal point.

The Mute button functions to mute the radio, as a decimal point when entering frequencies, and

as a clear to abort any key entry to that point. When using the Mute button as a clear, be sure to

press it enough times to get the LED to blink twice. This is confirmation that the clear command

has been accepted. When entering frequencies directly, the Mute key will operate as a decimal

point only after a digit key has been pressed before the first decimal point. As an example, you

can enter 0 Mute 3 Enter for 300KHz. Pressing the Mute a second time during direct frequency

entry will then enter 100Hz values. To enter 15.235.500 you would enter 1 5 Mute 2 3 5 Mute 5

Enter. Zeroes are assumed when not entered. You can enter 15.235.500 by pressing 15235

Mute 5 Enter. You can enter the frequency without any decimal places, but you need to enter all

the zeros so the frequency is not misunderstood. To enter 15.235.500 without using the decimal

key, enter 1 5 2 3 5 5 0 0 Enter.

The SWL IR Remote assumes that you are entering frequencies in kHz. Any frequency in kHz

can be entered directly. 9565kHz would be entered as 9 5 6 5 Enter. The decimal place (Mute)

is not necessary in this case. The decimal place is only needed to save zero entries or optionally

when entering a frequency less than 1MHz. When entering frequencies below 1MHz, press a

leading zero before the frequency and then Enter. For example: 0 7 0 0 Enter for 700kHz. Or

use the Mute key as a decimal place before or after the frequency entry. For example: 700

Mute Enter for 700kHz or 0 Mute 7 Enter for 700 kHz.

After a frequency has been entered, you can then use the CH+/- to step the frequency in the VFO

mode. Frequency steps of 10Hz, 100Hz, 1kHz, 5kHz, 9kHz, 10kHz, 100kHz, and 1MHz can be

used to adjust an entered frequency very quickly or step through stations with set frequency

spacing. Press a numeric key corresponding to the frequency step desired (see commands below),

and then the CH+/- and the step frequency will be used. The step frequency is kept and used

again the next time the CH+/- keys are used. The step is permanently kept when the radio is

powered off and back on with the remote Power button. The CH+/- keys will change the

frequency when in the VFO mode, and change memories up and down when in memory mode.

Frequency pacing is the rate at which the frequency is increased or decreased when the CH+/-

keys are held down. The pacing is a configurable parameter that can be set by the user. You can

speed up or slow down the rate at which the frequency changes by setting the frequency pacing.

The CH+/- keys are used to step the frequency up and down when in VFO mode. The first press

of the CH+/- in this mode will be slightly delayed. If the key is held down it will then begin

stepping the frequency at the current slewing rate. Use single presses of the CH+/- keys to move

slowly up or down in frequency. Hold the keys down continuously to step the frequency very

quickly.

If the VHF Converter option is installed in the R-5000, and the VHF Converter is enabled in the

SWL IR Remote, you will be able to enter and step through frequencies in the range of 108-

174MHz. The FM mode becomes selectable with the VHF Converter option.

Direct frequency entry is the same for the VHF Converter as in HF operation except for

frequencies above 100 MHz. An additional Mute is required for frequencies above 100 MHz.

Last Frequency Recall

The last directly entered frequency can be recalled. Use this when looking for other frequencies

being used by a shortwave broadcaster. You can set a frequency directly, enter another

frequency, and return to the original frequency. You can then enter another frequency and return,

etc. The last frequency entered is lost if power is removed from the remote control unit. It is kept

if the radio is powered off.

Tuning Steps

Pre-set Tuning Steps can be selected by entering a single digit before using the CH+/- keys on the

remote. The tuning step stays until changed again by the user. The Kenwood R-5000 has built in

tuning steps that are overridden by the radio when using the remote. You can tune all modes

except FM to 100Hz. Only SSB and CW modes can be tuned to 10Hz. FM steps are 5kHz and

2.5kHz.

Five User Tuning Steps can be defined for special tuning requirements. Set these tuning steps to

half the value of your filters. Tuning off frequency by half the filter bandwidth will improve

audio response without degrading the signal or losing synch lock. For example if you have a

2.4kHz filter, set User Tuning Step 1 to 1.2kHz and then tune off frequency when the 2.4kHz

filter is selected. This procedure is similar to using a PBT control, but you can see on the display

how much off frequency you are tuned. You could also set a User Tuning Step to a small value

and use it to quickly zero-beat the frequency in SSB mode.

Memory Operation

When moving through the memories, you can directly select a memory channel using the x (x)

(x) Last key sequence. For example, to select channel 23 you would press 2 3 Last. You can

select a memory channel in VFO or memory mode. You can also write the VFO to the currently

selected memory. Once the channel is selected, you can move the memory to the VFO using 0

Last, or move through the channels one at a time using the CH+/- keys. The CH+/- will change

the memory channel when in memory mode only.

The R-5000 memories are numbered from 0 to 99. The 0 memory channel cannot be directly

accessed with the SWL IR Remote. The 0 Last key sequence is used for moving a memory to the

VFO.

The remote will do the best job it can to track the current memory. When the radio is powered

off with the Power key on the remote, the current memory channel is put into semi-permanent

memory so it can be restored even after the remote control unit is powered off.

Mute Operation

There is a lot of functionality in the Mute key. The Mute key is used during frequency entry as a

decimal point. Any time a digit key is pressed before the Mute, the control unit then understands

the Mute to be a decimal point. At any time you can press the Mute key to clear any keys

pressed. The Mute may have to be pressed several times to get the LED to blink twice,

indicating that the keys have been cleared. If the radio mutes then you can be sure that the

sequence is cleared. The remote needs to know whether the Mute is being used for a decimal or

it is intended to be a clear. A clear function is interpreted by the remote control by multiple

presses of the Mute key.

Tuning Step 2 with a value of 1.4kHz would be 2 Mute 1 4 0 0 Enter.

The display on the radio will show the value as 2.140.000Hz when you

are done to confirm the entered value. It is best to set these tuning steps

with the receiver on and in the VFO mode. These steps are saved in non-

volatile memory and are never changed except using this configuration

mode.

LED Operation

The LED provides feedback on the mode and operation of the SWL IR Remote. The LED blinks

slowly whenever there is a communications error or the communications has timed out waiting

for a response when a response is expected. This can also occur if the radio is powered off and

you try to initiate commands.

Communications Error

The LED blinks continuously at a slow rate when the communication times out from the radio, or

a command is NAK’d. If the radio power is off and you try to initiate any command but power

on, the LED will indicate a communications error. If this occurs on every function and the radio

is powered on and not responding, check the cable connection to the radio.

This can also mean that the command is invalid in the current operating condition.

Clear Input

After the Mute is used to clear key entries the LED will blink twice.

Confirmation of Command

After a valid command has been issued and acknowledged the LED will blink once and go out.

The LED will appear to be on continuously when the CH+/- is held in the frequency mode

because the commands repeat and the LED doesn’t always time out.

Configuration Mode

When you enter the parameter configuration mode, the LED will blink continuously at a fast rate

until the configuration operation is completed or canceled.

RS-232C Level Converter

Description

The RS-232C Level Converter option connects to a computer through the DB9 connector on the

back of the SWL IR Remote unit. Just plug your computer into the SWL IR Remote and you can

use any software program that can communicate with your receiver.

The Level Converter is fixed at 4800 baud and cannot be changed.

Operation

The Level Converter takes in characters from a computer and sends them on to the radio, then

waits for return characters from the radio if the communications gets a response. Most Level

Converters just convert the electrical signals from RS-232C to TTL as required by the radio. The

SWL IR Remote has two serial channels (called a UART). One connects to the radio using TTL

level signals. The other channel is converted to RS-232C level signals and connects to a

computer. Going through the SWL IR Remote controller permits control over the flow of traffic

to and from the radio. IR commands can be interjected into the time between the computer

commands permitting operation by the computer and the Universal Remote.

There is a delay of about one character time when using the Level Converter. This is not enough

of a delay to cause any problems with most computer software. There is a normal turn around

time in the communications and the software, if properly implemented, should handle this delay.

Troubleshooting

Nothing happens when using the Universal Remote.

 Make sure the radio is powered. The power button on the front panel must be pressed in

(power on) for the remote to work with the ACC interface.

 Verify that the Universal Remote is in the TV mode. Check that the remote control box

is connected to the wall power supply and that the wall power supply is connected to the

AC supply.

 Check the batteries in the Universal Remote and change if necessary.

 Verify that the TV mode of the Universal Remote is set for a Sony TV.

The LED on the remote control unit blinks slowly.

 If no remote operations function, check cable connection to the radio.

 The power button should be on (pressed in) for the ACC interface commands to work. If

the power button is out, the interface will not work.

 The radio will ignore all commands while the radio is scanning. The Last key will work

to stop scanning.

 We have seen where the R-5000 will lock up when connecting to the ACC port. Remove

power from the R-5000 by unplugging it from wall power. Wait five minutes, and then

plug it back in to see if this clears up the problem.

The LED on the remote control unit blinks fast.

 The configuration mode has been selected and the operation needs to be completed. Push

Mute to cancel the operation or x x Enter to complete the operation. See chart above on

the configuration command parameters.

Some buttons on the control work, and some don’t.

 Verify that the Universal Remote TV mode is selected. If CABLE or VCR modes are

selected, only a few buttons will work. The power and mute will work in both modes.

None of the other keys will work in cable or VCR mode.

 Operate the buttons with more time between button presses. There is a 100 msec delay

between key presses so the remote control unit can tell if the button on the remote is held

continuously or has been released and pressed again. Each press of the remote will cause

a continuous stream of IR pulses to be sent (the LED on the Universal Remote will be lit

continuously). The remote control unit knows that the button has been released if the IR

pulse stream stops for 100 msec or longer.

Erratic Operation of the remote

 Check the batteries in the Universal Remote and replace if necessary.

 Be sure to aim the Universal Remote at the front panel of the control unit. The IR sensor

is behind the front lens to the left of the LED. This is more critical the further you are

away from the remote control box.

 Confirm that the interface cable is connected securely to the radio and the SWL IR

Remote control box.

 Check the power connection to the back of the SWL IR Remote control box.

Memory on the radio and the SWL IR Remote are not synchronized.

 If the memories are changed in any fashion other than the Universal Remote, the SWL IR

Remote can lose track of the currently selected memory. Use the SWL IR Remote to

perform memory operations, or select the memory channel directly with the SWL IR

Remote to synchronize the current memory channel after making memory changes other

than by using the remote.
