System error response

If the RE-350 has a fatal error which it cannot recover from while performing a command from the PC, the RE-350

will send this response and stop the current operation.

Mode error response

Depending on the mode, [ON-LINE] or [OFF-LINE], the RE-350 may not be able to execute some commands. In this

case, the Mode error response will be sent to the PC.

For Example: If the RE-350 is in the [OFF-LINE] Mode and the <Zoom Wide> command is issued, the RE-350 will

give a Mode error response because in this mode such a command cannot be executed.

Time out error response

When the RE-350 is given the command <OP AF> or <OP AWB> from the PC and it tries to perform the command

but cannot finish the operation successfully in an expected period, this error is given.

Request ON line

When the {RS-232} button on the front panel is pushed and the RTS signal line from the PC is on, the RE-350 will

send this “Event Data Packet” to the PC. If the RE-350 can receive the <Accepted> of the “E-response Packet” in 1

second, the RE-350’s mode will switch to [ON-LINE]. If not or no E-response after repeating the above “Event data

packet” twice, the RE-350 will stay in [OFF-LINE] mode.

Request OFF line

When the {RS-232} button on the front panel is pushed to try to set the RE-350 to [OFF-LINE] Mode and the RTS

signal line from the PC is on, the RE-350 will send this “Event Data Packet” to the PC. If the RE-350 can receive the

<Accepted> of the “E-response packet”, the RE-350’s mode will shift to the [OFF-LINE] Mode. Also, if there is no

response from the PC, then the RE-350's mode changes to [OFF-LINE].

If a control knob has not been used for longer than 500 milliseconds, the RE-350 will send the “FP-Data Packet” with

the corresponding control knob bit cleared.

Note: If the RTS signal line of the PC is off and the RE-350 is in [NOTIFICATION] Mode, the RE-350 will start to send

the “FP-Data Packet” which explains the button and control knob condition at the time when the RTS signal

line comes on.

If the PC is ready to communicate with the RE-350, the PC should set the RTS line to ON. The RE-350 will

recognize that its RS-232C connector is connected to the PC. When the RTS is OFF and the PC tries to send

some data, the RE-350 will disregard the sent data.

Once the RE-350 recognizes that the RTS of the PC is ON, the RE-350 will set the CTS of the PC to ON within

T1 after RTS is ON. The application software on the PC can recognize if the RE-350 is operating properly.

After the PC recognizes the CTS is ON, the PC can send the command packet to the RE-350.

Once the RE-350 receives the command packet, the RE-350 will set CTS to OFF and perform the operation

depending upon the command data from the PC to tell the PC that the RE-350 cannot receive another

command packet during this period.

After finishing the operation, the RE-350 will set CTS to ON to tell the PC that the RE-350 can receive another

command packet.

At the same time, the RE-350 will send the “C-response Packet” to notice the result of its operation. The

period (T4) between the reception and transmission of the “C-response Packet” is determined by the type of

command given.

Note: If the RE-350 does not follow the above timing chart, the power or connection of the I/ F cable is

incorrect.

If the PC wants to suspend the transmission of the “C-response Packet” data stream on its half, the PC should

set the RTS line to OFF.

Once the RE-350 recognizes the RTS of the PC is OFF, the RE-350 will hold the transmission of the “C-response

Packet” data after the remaining maximum 3 byte data in its communication buffer is transmitted. The

application software on the PC can recognize if the RE-350 is operating properly. The time period required for

transmitting the remaining data in the buffer will depend upon the communication speed of the RS232C I/ F.

When the PC wants to resume the transmission, the PC should set RTS to ON immediately. The longest time

period to be able to hold the transmission is 1000 milliseconds. If the PC fails to set the RTS line to ON in 1000

milliseconds, the RE-350 will stop the sequence to send the “C-response Packet”. The PC can not receive the

remaining C-response data any more.

Once the RE-350 recognizes the RTS signal comes back to ON within 1000 milliseconds, the RE-350 will resume

the transmission of the “C-response Packet” data.

Ap p e nd ix A – Disk Inform a tion

RE-350 Software Developer's Disk Installation

Description:

This disk contains one auto-extracting compressed file which once uncompressed contains 3 separate directories. The 3

directories are APP, 16BITSDK, and 32BITSDK. Within the APP directory is a Demo Application that was created using

the documentation and example data files in this SDK. The 16BITSDK and 32BITSDK directories contain .DLL and

Example application files for programming in a 16bit or 32bit environment.

How to Install the Compressed File From MS-DOS:

1. Create a directory named “RE350” on your hard drive. Copy the contents of the RE-350 Software Developer's Disk

into that directory.

2. From the RE350 directory, type “RE350SDK.EXE -d” at the “C:\RE350>” DOS prompt.

*** Make sure you use the -d option so that separate directories are created when the file is expanded. ***

Running this .exe file will create 3 directories, a 16BITSDK directory, a 32BITSDK directory and an APP directory

within the RE350 directory. See the following pages for a description of their individual contents.

How to Install the Compressed File From Windows:

1. Create a folder named “RE350” on your hard drive. Copy the contents of the RE-350 Software Developer's Disk

into that folder.

2. Using the Run command under the START button (Win95) OR the Run… command under the File menu in the

Program Manager (Win3.1), type “C:\RE350\RE350SDK.EXE -d” in the “Open:” text field box.

*** Make sure you use the -d option so that seperate directories are created when the file is expanded. ***

Running this .exe file will create 3 directories, a 16BITSDK directory, a 32BITSDK directory and an APP directory

within the RE350 directory. See the following pages for a description of their individual contents.

RE-350 Demo Application (\ APP)

How to Use the Demo Application:

The RE-350 Demo Application is a 16bit application that runs under Windows 95 and Windows 3.1.

1. Connect the RE-350 to the computer. Using a correctly pinned RS-232 cable (pp.57–59) connect one end to the RS-

232C output on the RE-350 and connect the other end to an available COM port on your computer.

2. Turn on the RE-350 and the computer and launch Windows.

3. In the APP directory that was created from the SDK disk is a file named CTL3DV2.DLL. This file should be placed

into your System folder within Windows [c:\Windows\System].

4. Double click on the RE-350 Demo Application icon in the APP directory.

When the application has successfully launched, the On-Line LED should be lit on the RE-350's front control panel

and within the GUI of the software interface.

Very simply the RE-350 Demo Application offers remote operation of all manual buttons and control knobs located on

the front control panel via the RE-350 graphical user interface.

If the Application Does Not Launch Properly Check:

COM Port Setting – The COM port setting selection in the RE-350 Demo Application should match the COM port

the RE-350 is connected to on the computer.

ID Setting –

Baud Rate –

Cable –

The ID Setting on the rear panel of the RE-350 (p.3) should match the ID Setting the RE-350 is

set to.

The Baud Rate setting selection in the RE-350 Demo Application should match the baud rate

selected via the switch on the rear panel of the RE-350 (p.3).

Make sure you are using a correctly pinned cable. Check with the pin out diagram on pp.57–59.

Open the project in Microsoft Visual C/ C++ to edit and recompile.

The DLL and example application are built separately. You can use RE350DLL.DLL as is by importing the functions

described below (or in RE350.H ).

You can also rebuild the application in MS-DOS by typing:

nmake -fre350dll.mak

nmake -fexample.mak

2) RE350.C and RE350.H constitute the basic driver and are generalized to work with any application. All of the

functions return an error code (defined in RE350.H ) to indicate whether the operation was successful.

Initialize communications with the RE-350:

int FAR PASCAL

int iComPort:

RE350_Open( int iComPort )

RE350_COM1-RE350_COM4

Execute an RE-350 command:

int FAR PASCAL

int iDevice:

RE350_Command( int iDevice, int nCmd, WORD wRequest, LPWORD lpwResponse );

device 0-3 (check dip switch on the back)

Command defined in RE350.H .

int nCmd:

WORD wRequest: Request data if required by command.

(Use RE350_NULL_REQUEST if not required).

LPWORD wRequest:Pointer to response (or NULL).

Close communications with the RE-350:

VOID FAR PASCAL

RE350_Close( VOID );

4) EXAMPLE.C is a simple application which demonstrates the operation of the driver. After getting this to compile in

your environment, you can add additional commands (via RE350_Command) to test the camera’s operation.

All of the RE-350 commands are implemented through this function.

RE-350 32bit Sample Code (\ 32BITSDK)

Notes:

1) This example application was written and compiled with Microsoft C/ C++ and SDK Version 4.0 (32 bits ONLY).

Open the project in Microsoft Visual C/ C++ 4.0 to edit and recompile.

2) The RE-350 driver (RE350.DLL) is located in .\EXAMPLE\RE350 and has been setup as a sub-project of EXAMPLE.

It will be automatically updated if EXAMPLE is set as the project. The output is directed to the EXAMPLE\RELEASE

directory so any changes made to the DLL will be automatically loaded by the application next time it is run.

EXAMPLE explicitly loads and unloads the DLL using LoadLibrary() and FreeLibrary() to facilitate this (see

EXAMPLE.C).
