Thank you for purchasing the CU8232 computer control interface for operation with the AR2700 receiver. Every effort has been made to make this supplement correct and up to date. Due to continuous

development of the product and by error or omission anomalies may be found and these are acknowledged. Most apparent faults are usually due to accidental misoperation of the product, carefully read all of the

manual and relevant sections in the AR2700 operating manual before deciding to return the interface for repair.

(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 IBM compatible DOS and Microsoft WINDOWS packages to support the AR2700 receiver.

The CU8232 interface also enables data to be copied between two AR2700 receivers when simultaneously connected to the CU8232. All operating, memory and search bank data may be transferred and is accomplished without the use of a host computer and the interface is powered from the AR2700 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 (CU8232 & AR8000) One

Optional - AR2700 supplement (this booklet) One

(3) AR2700/CU8232 connection & clone

1. A ribbon cable is used to connect the AR2700 to the CU8232. One end of the ribbon cable has a

reinforced plate, this is used at the AR2700 end of the connection. Insert one flat cable (they are both identical) into the CU8232 [PROGRAM] socket contact (metal) side downward.

Connection & clone

The [PROGRAM] socket is the primary receiver connection used for computer control. This port also takes power from the receiver (when the AR2700 is switched On).

Should you wish to CLONE data between two AR2700 receivers, connect the second ribbon cable to the socket labelled [COPY].

2. Remove the battery compartment lid of the AR2700 using a downward sliding motion. 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 facing toward the front of the receiver and the blue tab facing you (so that the cable is not twisted)

IMPORTANT

If the receiver has a four pin remote socket the optional IF-ADP cable will be required... in which case please contact your dealer.

It may be difficult to insert the flat cable into the CU8232 or AR2700 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 AR2700 connected to the [PROGRAM] socket. When the receiver is switched On, the AR2700 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 AR2700 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.

4. Switch both receivers On and run the CLONE functions as detailed on page 57 section 15 of the AR2700 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. ¶ Always press the [ENT] key of the AR2700 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 AR2700 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.

(4) Connection for RS232 operation

The connection and setup parameters are identical to those for the AR8000 receiver... for this reason please refer to page 6 section 4 of the main CU8232 operating manual.

ATTENUATOR ON/OFF.

Commands AT AU BM

ATn[ï] n = 0 ATT OFF

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

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

n = 1 ATT ON

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

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

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.

n = 1 AUTO MODE ON

Related commands MD MX RF SE ST

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 1 2 - - 5 - - - 9 To switch bank link Off type in the reported scan bank letters:
