General : Accessories : Connection & clone

(1) General

The CU8232 interface allows computer control via the RS232 serial port of a computer. An additional piece of software will usually be required in order to address the computer’s serial port with the correct set of parameters. If using an IBM-PC or clone (with 80386 processor or higher) Microsoft WINDOWS “TERMINAL” may be used to address the computer’s serial port, configuration of “TERMINAL” is covered later in this manual.

In order to gain the greatest flexibility, a specialist software package is desirable. It is planned to later introduce a Microsoft WINDOWS package to support the AR8000 receiver.

The CU8232 interface also enables data to be copied between two AR8000 receiver when simultaneously connected to the CU8232. Memory, search and all data may be transferred enabling full CLONE of one receiver onto another. This may be accomplished without the use of a host computer and the interface is powered from the AR8000 receiver.

(2) Supplied Accessories

Please check that the following items are included in the package:

Description Quantity

CU8232 remote control interface box One Flat cable Two RS232C 9-pin to 25-pin adaptor One RS232C 9-pin male-Female adaptor One English language operating manual (this booklet) One

1. A ribbon cable is used to connect the AR8000 to the CU8232. One end of the

AR8000/CU8232 connection & clone

ribbon cable has a reinforced plate, this is used at the AR8000 end of the connection. Insert one flat cable (they are both identical) into the CU8232 [PROGRAM] socket contact (metal) side downward.

Connection & clone

Figure 1

The [PROGRAM] socket is the primary receiver connection used for computer control. This port also takes power from the receiver (when the AR8000 is switched On).

Should you wish to CLONE data between two AR8000 receivers, connect the second ribbon cable to the socket labelled [COPY].

2. Remove the battery compartment lid of the AR8000 using a downward sliding motion.

Figure 2

Locate the remote control socket which is located at the bottom edge of the battery compartment. Insert the ribbon cable (with the reinforced plate) contact (metal) side downward.

Figure 3

Connection & clone

It may be difficult to insert the flat cable into the CU8232 socket for the first time as they are necessarily quite tight. If this is the case, try inserting with a little upward pressure, it should become easier the next time. DO NOT APPLY EXCESSIVE STRESS TO THE FLAT CABLE UNDER ANY CIRCUMSTANCES.

A DC voltage is fed to the CU8232 by the AR8000 connected to the [PROGRAM] socket. When the receiver is switched On, the AR8000 DATA is routed to the RS232 connector.

If a second receiver is connected to the [COPY] socket and switched On, the CU8232 recognises it’s presence and routes data between receivers and not to the RS232 socket.

3. To CLONE data between two AR8000 receivers, connect each receiver to the CU8232 using a ribbon cable as outlined above. Data may be transferred in BOTH direction between the [PROGRAM] and [COPY] sockets.

Figure 4

4. Switch both receivers On and run the CLONE functions as detailed on page

102 section 19 of the English language operating manual.

Caution! Make sure that no low / flat batteries occur while the data clone is in progress. Although no significant extra current is required for clone operations, flat batteries may cause corrupted data transfer. It is advisable that the receivers are both powered from their chargers (which were supplied with the receivers) during clone operation.

5. If a data clone fails retry the procedures of clone operation after checking the following:

¶ Make sure that all connections are correct and there is no loose contact. ¶ Ensure that one receiver is in TRANSMIT mode and the other is in

RECEIVE mode.

- 5 -

Connection & clone : RS232

¶ Always press the [ENT] key of the AR8000 in RECEIVE mode first so that it is ready to accept data.

¶ Press the [CLEAR] key of the receiver prior to the retry if the failure is due to incorrect connections or an error in key sequence.

6. An alternative method may be used to connect two AR8000 receivers for data CLONE. Two CU8232 interfaces may be employed with each AR8000 connected to the [PROGRAM] socket. The RS232 9-pin connectors are linked using a three wire crossed cable:

CU8232 CU8232

Pin 2 Pin 3 Pin 3 Pin 2 Pin 5 Pin 5

No other pins are used.

Figure 5

(4) Connection for RS232 operation

The remote facility enables the AR8000 to be operated via a computer such as an IBM-PC or similar, basic remote control terminal or dedicated software will be required to address the AR8000 through the CU8232.

Switching the receiver On/Off, setting of volume and adjustment of squelch cannot be achieved via the RS232 port.

Computers “always” generate RF noise which may interfere with the AR8000 reception if the standard helical rubber aerial is used. To reduce the effects of noise, use of a remote aerial is highly recommended with good quality 50 OHM coaxial cable employed.

- 6 -

RS232 operation

Connect the AR8000 to the [PROGRAM] socket of the CU8232 as outlined earlier in section (3) and figure 1.

Connection to a computer is via the rear panel RS232C 9-pin “D” type female socket. Should you require a male socket then a 9-pin gender changer is supplied in the package. Should you prefer to use a 25-way “D” type female socket, an adaptor is also supplied as standard.

Always use a straight RS232 cable (null modem is not to be used!). The RS232 cable should be of good quality and no more than 2m in length. As the CU8232 is powered from the AR8000, excessive cable length may cause lost data between the AR8000 and computer.

Connection for an IBM-PC or clone is as follows:

CU8232 9-PIN IBM-PC 9-PIN

22 33 5 5 (Ground)

All other pins not used but pins 4, 6 & 8 are linked together inside the CU8232. Some software requires the linking of CTS/RTS at the computer end of the cable (pins 7 & 8).

CU8232 9-PIN IBM-PC 25-PIN

23 32 5 7 (Ground)

All other pins not used but pins 4, 6 & 8 are linked together inside the CU8232. Some software requires the linking of CTS/RTS at the computer end of the cable (pins 4 & 5).

Communication parameters : WINDOWS TERMINAL

(5) Communication parameters

Communication between the AR8000 and computer (via the CU8232) uses semi-duplex. Refer to both the English language operating manual (page 101 section 18-1) and the computer handbook for correct settings.

Baud rate: 2400, 4800, 9600 selectable Delimiter: CR or CR,LF selectable Stop bit: 2 BIT Parity check: None

The PC requires X-parameter flow control.

Both the computer and AR8000 must use the same parameters for correct operation.

If data is regularly lost or corrupted, try using a slower speed such as 4800 or 2400 baud. Use of a slower baud rate should not greatly reduce overall communications transfer rate since the processing time within the receiver and PLL lock-time ultimately restricts the whole process.

Note: When changing BAUD rate, switch the AR8000 Off/On to

ensure the new speed is selected.

(6) Use of Microsoft WINDOWS “TERMINAL”

Assuming you have DOS and WINDOWS 3.1 (or later) loaded on an IBM-PC compatible computer, WINDOWS “TERMINAL” may be used to address the CU8232 and AR8000 receiver to enable basic remote operation.

Start WINDOWS by typing WIN at the DOS prompt. Locate the [TERMINAL] ICON in the program manager ACCESSORIES group and double-click.

Sending a command

¶ For further information regarding WINDOWS TERMINAL and configuration, please refer to the operating manual supplied with Microsoft software and the computer.

Click on “COMMUNICATIONS” then select the options as shown in figure 11. The choice of COM port (COM1, COM2 etc) will depend upon your computer serial port and mouse configuration. Finally click on [OK].

(7) How to send a command

Each command comprises of two upper case letters (header) along with options as required. All commands use ASCII code which MUST BE IN UPPER CASE (except for the “ARROW” é ê which uses the control code of ASCII).

A multiple command entry is only valid where specified. Where a multiple command entry is allowed, each command MUST be separated with a space “h20” (HEX DECIMAL).

Each command is completed with a [CR] or [CR],[LF] whichever is specified in the AR8000 receiver configuration (page 101 section 18-1 of the English language AR8000 operating manual), thereafter described as [ï].

Although there is no local echo, either [ï] or a specified response should come back from the receiver after confirming the correct command.

A space is often shown as "_" in the following examples.

REMOTE indication

When the AR8000 has received a command via the RS232C port the receiver’s LCD with alternate between the top line of data and the wired “REMOTE”. When remote mode is engaged the receiver’s keypad becomes inoperative. To restore operation to the receiver’s keypad press [LOCAL] - effectively remote operation is cancelled. Remote mode is re-engaged when a new command is received via the RS232C port.

The receiver always acknowledges the receipt of a command by sending [ï] (as specified in the receiver configuration) or will respond with the requested data. Only send a second command after the first command has gained a response.

If no response has been gained after a short while, the receiver has failed to receive the command properly. Send a [ï] then re-send the command. Should problems persist, check your serial / CU8232 connections and try reducing the RS232 baud rate.

n = 1 ATT ON

Multiple commands in conjunction with other commands are possible with a space in between: AT, AU, MD, RF, ST, VA, VB.

Example: AU0_MD3_RF145.2_AT1[ï] AT[ï] checks the current attenuator setting, the response being: AT0 = ATT OFF

AT1 = ATT ON Related commands MD MX RF SE VA VB

AUTO MODE (and step) ON/OFF. AUn[ï] n = 0 AUTO MODE OFF

n = 1 AUTO MODE ON

Multiple commands in conjunction with other commands are possible with a space in between: AT, AU, MD, RF, ST, VA, VB.

Example: AU0_MD3_RF145.2[ï] AU[ï] checks the current auto mode setting, this is not valid when “M.RE” or

“SCAN” is in use. The usual response to the AU request being: AU0 = AUTO MODE OFF

AU1 = AUTO MODE ON - step size and receive mode set automatically. Related commands MD MX RF SE ST VA VB

SCAN BANK LINK ON/OFF (specifically). BM[ï] checks the current status of linked scan banks. If bank letters are specified then scan bank link is On (the specified banks will be

scanned as a group), if no letters are specified then the facility is Off. First check the current status by typing BM[ï] A typical response may be: BM -BC—GHIJa—e—h-j To switch bank link Off type in the reported scan bank letters:

BM BCGHIJaehj (lower case input being accepted for the second group of memory banks)

To activate a new scan bank link type in the required list of scan bank letters. For example to link a few specified scan banks and turn the facility On:

Type BM followed by the bank letters and terminated with [ï]

BM ABDabcij [ï]

The BM command may be used to switch some banks On and others Off at the same time. To make things easier a “-” character reverses the current status of the specified bank, of course this may also be used to switch scan bank link Off.

Note: The SCAN BANK LINK facility can also be simply switched On/Off using the ML command.

BS is the equivalent command for SEARCH bank link. Related commands ML BN XA XB XD XM XO XP XQ

LC : LM

The LC command caused the receiver to supply FREQUENCY and S-METER level only when the squelch is opened. A new response will be repeated automatically when the squelch is closed and opened again.

The automatic data response will only be supplied when ALL squelch parameters are met (level scan, audio scan etc).

To terminate the facility send another command. LC[ï] will report the present receive frequency and S-meter. The S-meter report

is in 64 steps from hex decimal 00 to 3F. A typical response may be: LC1B_RF0145300000
