1. Introduction
1.1 Communications overview
The Autostart AS731 and AS732 provide full-function, automatic or manual control for diesel generators.
Both units include an RS232 interface that allows communication with other RS232 equipment such as
PCs and modems. When used with software model
AS7CN for PC and Windows®, the system allows a remote PC operator to program, monitor and control an Autostart and generator.
Model AS732 additionally features an RS485 Modbus® interface, allowing communication between several
AS732s (e.g. in a multi-genset system) or between
AS732s and other RS485 equipment (e.g. PLC, SCADA or building management systems).
This document details the communication features of
AS731/AS732 firmware versions V2.2.x, along with the installation and operation of (fully compatible) software
AS7CN versions 2.2.x.

2.1 RS232 communications
2.1.1 General
The Autostart RS232 port uses an RJ11 connector on the rear facia, as shown in the diagram on page 1.
The RS232 link is typically used to communicate with a PC running Murphy software AS7CN, which may then be used to program, monitor or control the Autostart and generator system. As detailed in the diagrams at the foot of this page, the link may be ‘local’ (up to 10 metres using a simple RS232 serial lead) or ‘remote’ (any distance, using suitable RS232 modems and the telephone network).
2.1.2 RS232 accessories
The following accessories are available from Murphy:-
Model Description
AS7CP R232 local comms (null modem) lead,
RJ11 to 9 way D type
AS7CQ RS232 adaptor for optional use with AS7CP,
9 way D to 25 way D.
AS7CR RS232 modem lead, RJ11 to 25 way D type.
A ‘local’ serial link requires the use of lead AS7CP: this lead alone is sufficient if the PC has a 9 way COM port; if the PC has a 25 way COM port, adapter AS7CQ is also required.
‘Remote’ communication typically requires the use of modem lead AS7CR, two modems (with telephone connections), and a modem to PC lead. Note: Murphy is unable to supply modems or modem-PC leads.

2.1.3 RS232 connection - general
IMPORTANT: Before attempting any RS232 connection, ensure that AS731/732 pin 1 (battery negative supply on the main terminal block) is connected to earth/ground, and that the Autostart is switched off. This is a necessary precaution to avoid excessive (possibly destructive) earth currents when connecting to certain RS232 equipment.
WARNING: failure to connect pin 1 to negative DC and ground may result in permanent damage to the Autostart or connected RS232 equipment (e.g. PC
or laptop).
2.1.4 RS232 local connection (distances up to 10 metres)
For distances up to 10 metres, PCs with a 9 way COM port can be connected directly to the AS731 using lead
AS7CP. For PCs with a 25 way COM port, use an additional adapter model AS7CQ.
To connect up a local link:-
1. Ensure that both Autostart and PC are powered down.
2. Connect the RJ11 (telephone type) plug of lead
AS7CP into the AS731/732 RS232 socket.
3. The other end of lead AS7CP can be connected directly into PC’s with a 9 way COM port. For PCs with a 25 way port, connect adapter AS7CQ between the lead and PC port.

2.1.5 Remote (Modem) Communication
Two modems are required, one connected to the
Autostart at the generator site, the other connected
(or internal) to the PC at the remote control site. The modems must be RS232 and Hayes AT compatible, and must comply with the technical and legal requirements of the connected telephone network.
At the Autostart/ generator site, the modem should ideally use an uninterruptable power supply (usually a battery/DC system). If the Autostart is required to dial out on fault conditions, the generator site must be enabled for a tone dialling (rather than pulse dialling) telephone system.
3. PC software AS7CN
Model AS7CN is a software tool that allows RS232 communication between an Autostart AS731/AS732 and a PC/Windows® compatible system. The
Windows®-based interface allows a PC user to monitor, control and program a locally or remotely connected
Autostart system. (Note: the software does not allow direct communication to an AS732 RS485 network, but connection to an AS732 RS232 port can be used as a
‘gateway’ for the interrogation and control of multiple
AS732 controllers on a common RS485 network.
Before attempting to install or operate the software, please read the following sections in full.
To connect the generator site:-
1. Ensure that both modem and Autostart are powered down.
2. Take lead AS7CR and connect the RJ11 (telephone type) plug into the Autostart RS232 socket.
3. Connect the other (25 way D-type) end of the lead into the modem RS232 port.
4. Connect the modem telephone and power supply leads as specified by the modem manufacturer.
5. Power up the system: modem first, then Autostart.
At the PC control site, ensure that the modem is correctly fitted to the PC, either internally as a modem card or externally via a serial port. Refer to the modem manufacturer’s instructions if required.
3.1 Software Installation
Before communication can occur between a PC and
Autostart, software AS7CN must be correctly installed and configured.
3.1.1 Compatibility
The following information relates to AS7CN software versions 2.2.x, which is fully compatible with AS731 and
AS732 firmware V2.2.x. AS731s with older firmware
(V1.00 to V2.1.0) will communicate with the latest software but are not fitted with some of the latest programmable features. Software V2.2.x is NOT compatible with AS732 firmware V2.00 (Modbus ASCII version).
2.2 RS485 communications (AS732 only)
An RS485 network is formed by daisy-chaining units as shown in the diagram at the foot of page 2. Interconnection is via leads with RJ45 plugs and screened cable, such as those found in 100BaseT Ethernet systems: use CAT5 cable as a minimum; CAT5E cable is recommended.
The total length of the network must not exceed 1000 metres (approx 3300 feet). Network terminator modules are supplied with each AS732 and should be left inserted into any unconnected sockets, i.e. in units at either end of the network.
Software AS7CN is designed for use on any PC or
PC compatible laptop running English versions of
Windows® ’95, ’98, ME or 2000. The software supports communication by RS232 serial port using an internal modem or external modem with designations COM1, 2, 3 or 4.
3.1.2 Software Availability
Software AS7CN is available from Murphy as a single, self-extracting file. The latest version of this file, named as7cn_v2_2_0.exe, is available as a free of charge download from our website

“Murphy AS731…“ – then click the Add/Remove… button.
• The InstallShield® wizard will run. Select the ‘remove’ option, then click Next >
• Follow the wizard instructions. Warning messages may be displayed about removing shared Windows® components. If a newer version of AS7CN is to be installed immediately afterwards, it is generally safe to remove the shared components by selecting ‘yes’
(and also ticking ‘don’t display this message again’).
If, however, the software is to be permanently removed, or if you are in doubt, it is safest to keep the shared components by selecting ‘no’ to each warning.
Additional uninstall notes:-
When run for the very first time, the software will also ask the operator to configure the PC communication port - see section 3.4 below for full details.
Three buttons on the main menu screen - ‘monitor’,
‘program’ and ‘log calls’ - allow the operator to select one of three (mode) screens:-
• Click Monitor to upload and display real time data about the status of the connected system, and for limited control over the system. Full details are given in section 3.6.
• Click Program to view and edit AS731/732 program
‘profiles’. Each profile contains settings for timers, input/output configurations, etc. Profiles may be opened from disk, saved to disk, uploaded from or downloaded to the Autostart and printed out.
Full details are given in section 3.7.
• Click Log calls to get the software to wait for incoming calls from remote Autostart units. The site name and fault condition is displayed on screen and logged for later review. See section 3.8 for full details.
3.3 Drop-down menus
1) The procedure above does not remove *.731 or *.732 files, which are created when custom AS731 (program mode) ‘profiles’ are saved to disk (see section 3.7 for details of Autostart program ‘profiles’).
The menu bar has several drop-down options, similar in style and operation to other Windows® based software:-
2) Program profiles (*.731 files) that have been saved to disk using software AS7CN V1.02 or earlier CANNOT be read by AS7CN V1.03 or later. If you have older profiles on disk and want to use these with V1.03 or later software, please consult your Murphy representative.

The Settings menu allows configuration of the PC RS232 communication port, and the selection of ‘local’ or ‘remote’ communication mode (see section 3.4 below).
The currently selected option is highlighted with a tick.
The Modem menu options are only available when the
PC is fitted with a modem.
These options allow the user to connect and disconnect a communications link with a remote Autostart.
This menu is not required when communication is ‘local’ - the software automatically establishes a connection through the local serial port.
Help Includes hyperlinks to
Murphy website home and
Autostart pages.
Help|About gives details of the software and its version number.
3.4 Configuring the PC communication port
Each PC serial port or modem is assigned a COM port number by the Windows® operating system. Before communication can occur with the Autostart, the software must be set with the number of the COM port to be used.
The configuration screen below launches automatically when the software is run for the very first time. These settings can also be changed at any time by selecting clicking the Settings|Com ports menu option:-
For both local and modem (remote) port settings, click on the correct COM port number, or on the ‘not used’ option. If the correct COM port is not known, refer to the PC manufacturer’s data. If an incorrect COM port is entered, the software typically displays ‘can’t open
COM port’.
Note: For local communication, the PC serial port may be physically labelled with the COM setting.
On older PCs, the serial port is often designated as
COM2 (with COM1 reserved for the mouse). On newer
PCs and laptops, the mouse often has its own dedicated connector and the serial port is often designated COM1).
For modem (remote) communication, the modem may be external or internal to the PC. An external modem is connected via a serial port, with its own
COM setting as for local communication (often COM1 or COM2). An internal modem card does not use a serial port connection, but is still allocated a COM number (often COM 3 or 4).
The modem initialise strings (outgoing and incoming) contain Hayes AT commands to set up the modem operating characteristics. These should only be edited by experienced modem users. Below this, a separate software control allows the PC modem to use either tone or pulse dialling mode.
3.5 Making a connection
Before a communication link can be established between software and Autostart, the Autostart must be connected and powered up. The software allows selection of ‘local’ or ‘remote’ communication modes.
3.5.1 Local connection
For a local connection (using a simple serial link) click on Settings|Local Connection. The software then attempts to establish a link to the AS731/732 through the specified serial (COM) port.
3.5.2 Remote (modem) connection
‘Remote’ communication requires that a modem is fitted to the PC and that the software has been set up correctly for that modem (see section 3.4). To make a connection to a remote Autostart:-
Click on Settings|Remote Connection. This drop down menu option is only available if the software detects that a modem is fitted to the PC.
Click on the Modem|Connect drop down menu item to display the following dialog box:-

pre-programmed numbers (see 3.5.3 below for details). Note: when dialling through a private exchange, additional prefix numbers may be required, e.g. ‘9’ to access an outside line, and ‘,’ (comma) to
wait for the outside line dial tone.
• Click the mouse in the Remote PIN box and type in the correct access PIN (personal identification number) for the remote Autostart. The factory default PIN is 5678.
• Click on Dial
The PC modem then dials out to the remote Autostart modem. The connection progress is displayed in the
‘status’ area. After a successful connection, the software displays a ‘connected’ message - programming, monitoring and control of the Autostart are then exactly as for a ‘local’ connection. If a connection is not successful (e.g. due to a modem fault or incorrect PIN), appropriate error messages are displayed.
Disconnecting a remote connection
When monitoring or programming of a remote Autostart is complete, end the modem session by selecting the
Modem|Disconnect drop down menu option.
3.5.3 Using the address book
Access to the address book is from the Dial dialog box
(see section 3.5.2 above). The address book allows storage and recall of 20 site names and modem numbers:-
Single genset (‘full’) monitor screen (all units)
To view existing entries, click on the Name drop down list and select the contact required: the corresponding phone number is shown in the Phone number box.
To use the highlighted contact and return to the ‘Dial’ dialog, click on Use.
To modify existing entries, or create a new contact, click the Modify Entry or New Entry buttons. Type the new details in the boxes provided, then click Store.
3.6 Monitor Mode
Once a connection has been established between PC and Autostart, the generator status can be monitored by clicking on the View|Monitor drop-down menu or the main menu Monitor button.
In monitor mode, data about the generator system is uploaded from the Autostart and displayed in real time.
When monitoring an AS731, the software displays a
‘single genset’ screen format below left, providing ‘full’ details about the Autostart, engine and AC parameters
(see numbered points following for more detail).
When monitoring an AS732, the software displays a ‘multi-genset’ screen format (shown below right).
This screen can display summary information for several generators, using data passed via RS232 from a ‘master’ AS732 (which in turn has collected data from a number of RS485 networked ‘slave’ AS732s).
On this multi-genset screen, the operator can a) read a summary text status for each genset, b) start and stop each genset, and c) press the ‘full monitor’ button to display details (screen as below left) for each genset.
The key features of the single genset screen are, as labelled on the diagram below left:-
1 Communications status. The green LED simulation flashes while communication is in progress between software and Autostart. No flashing indicates that the communication link has broken or stalled.

3.7 Program mode
The AS731/732 has around 50 programmable features
– timers, inputs, outputs, control options, etc. Software
AS7CN allows the creation and editing of program
‘profiles’, each profile being a collection of individual function settings. The software also allows profiles to be saved to and opened from the PC hard disk, floppy disk or network drive, and uploaded from or downloaded to the Autostart (see section 3.7.2).
To select the program screen, select the View|Program drop down option, or click on the main menu quick launch Program button. The program mode screen also opens automatically if an Autostart profile is loaded
(e.g. by clicking on File|Open Profile from disk or
File|Upload Profile from Autostart).
The program mode screen has eight selectable tabs, each of which allows the operator to view and edit a sub-set of the profile settings. The program mode screen typically opens with the ‘Profile’ tab selected, as follows:-
3. Generator set-up 1
4. Generator set-up 2
5. DC variables
3.7.1 Viewing and editing settings
Click on the appropriate tab to view each group of program settings, then use the mouse to edit the value, option or text for each function. The eight screens are shown below for reference, but full details of the individual program options are listed in installation (programming) document mi6129.
1. Profile
In the opening screen shown above, the operator can enter notes about this particular program profile. The notes are stored with the profile (either to disk or within the Autostart) and will appear whenever the profile is opened or uploaded.

3.7.2 Managing Profiles
Use the File drop-down menu for storing and retrieving program profiles, to or from either disk or
AS731/732.
Opening from/saving to disk
Profiles may be opened from and saved to disk regardless of whether an
Autostart is connected or not. Profiles may be saved to disk with a .731 or .732 file extension (according to user preference – both file types can be read by either
AS731 or AS732 units). The filenames should be chosen to allow organised storage and later recall, e.g. “siteA.731” or “siteXYZgen1.732” etc. The default save directory is
C:\Program Files\Murphy\ AS7CN\Profiles\, but the software allows selection of any location on hard disk, floppy disk or network drive.
When a profile is opened from disk, the filename appears in the software title bar. The profile remains open if the operator switches between program, monitor or main title screens. If no profile is open
(e.g. immediately after start-up), selection of ‘program’ from the main title screen causes the automatic opening of the default factory profile (filename defaults.731).
Uploading from/downloading to an AS731/732
Once the PC is connected to an AS731 or AS732, profiles may be saved (downloaded) from the PC to the
Autostart, or opened (uploaded) from Autostart to PC.
Note that the profile filename is not stored in the
Autostart, and that the software allocates the filename
“upload” to all uploaded profiles.
The download of Autostart profiles typically takes a few seconds to complete, but can take longer - up to 25 seconds - when certain program settings are changed
(e.g. a change to the AC over current settings usually results in the Autostart having to recalculate it’s calibration tables).
The transfer status of all downloads and uploads is displayed by the software, and appropriate error messages are shown if the communication link or transfer process fails.

3.8 Log Calls
Where a modem communication link has been set up between PC and modem, the ‘log calls’ mode allows the software to wait for and log incoming calls from remote
Autostart units. In order to use this feature, the Autostart/ generator site modem and telephone exchange must employ a tone dialling (rather than pulse dialling) system.
To use this facility, program each Autostart with one of the ‘dial out on fault’ options (shutdown faults only, or warning and shutdown faults), and with the telephone number of the PC/modem which is to be used to log calls: for full details of programming, see document mi6129.
At the PC end, select this software mode by clicking on the main menu Log calls button, or on the View|Log
calls menu option. The screen displays:-
3.9 Exit
To exit the software, select the File|Exit drop down menu item.
For each incoming call, the software records the details of the Autostart site name, fault type, and the time and date received. The information is added to a text file named faultlog.txt (stored on the PC in the software’s installation directory), which is then displayed in the large scrollable area shown above.
Once a fault message has been logged, the software runs a short (10 seconds) timer, during which the PC operator (if present) has the option of maintaining communication. If this timer expires, the software automatically breaks off communication, freeing itself to receive other calls.
If the Autostart dials out but fails to log the fault
(e.g. if the PC is switched off, or the modem is already engaged, or the software is not in ‘log calls’ mode), the unit breaks off communication then automatically retries every minute; the Autostart will retry indefinitely, until the fault is logged.
