Function of {RS-232} button
By pressing this button, toggles the RE-350's RS232C I/F from active to inactive for communication with the PC or
another controller device.
Once the RE-350 detects that the {RS-232} button was pressed, the RE-350 will send an Event data packet to the PC
through the RS232C I/F to tell the PC that the operator is trying to change the mode.
The Event data packet will differ according to the RE-350's current mode.
Current Mode
OFF
ON
Notification
The Kind of Event-data-packet
LineRequest ON Line

Note:
1. The RE-350 will shift its mode after the RE-350 receives an <Accepted> E-response data from the PC.
The RE-350 can not shift its mode to [NOTIFICATION] Mode directly. In order to set RE-350 to [NOTIFICATION]
Mode, the PC has to give the <Notification> command to the RE-350 while in [ON LINE] Mode.
2. After the {RS-232} button is pressed and before the mode of the RE-350 is determined, the RE-350 will be in a
mode transition. To tell this transition status to the operator, the RE-350's RS-232 LED will blink. While the RE-350
is in this transition, every button, control knob or command from the PC, will be disregarded.

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.

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].

1 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.
2 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.
3 After the PC recognizes the CTS is ON, the PC can send the command packet to the RE-350.
4 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.
5 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.
6 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.

1 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.
2 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.
3 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.
4 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.

Appendix A – Disk Information
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 RS232C 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 –
The ID Setting on the rear panel of the RE-350 (p.3) should match the ID Setting the RE-350 is
set to.
Baud Rate –
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).
Cable –
Make sure you are using a correctly pinned cable. Check with the pin out diagram on pp.57–59.

RE-350 16bit Sample Code (\16BITSDK)
Notes:
1) This example application was written and compiled with Microsoft C/C++ and SDK Version 1.52 (16 bits ONLY).
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
RE350_Open( int iComPort )
int iComPort:
RE350_COM1-RE350_COM4
Execute an RE-350 command:
int FAR PASCAL
RE350_Command( int iDevice, int nCmd, WORD wRequest, LPWORD lpwResponse );
int iDevice:
device 0-3 (check dip switch on the back)
int nCmd:
Command defined in RE350.H.
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).
3) 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
RE350_Open( int iComPort )
int iComPort:
RE350_COM1-RE350_COM4
Execute an RE-350 command:
int FAR PASCAL
RE350_Command( int iDevice, int nCmd, WORD wRequest, LPWORD lpwResponse );
int iDevice:
device 0-3 (check dipswitch on the back)
int nCmd:
Command defined in RE350.H.
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.
