1.3.4 Procedure for Using the {RS-232} Button

Function of {RS-232} button

By pressing this button, toggles the
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 RS232C I/F from active to inactive for communication with the PC or

RE-350's current mode.

Every data packet consists of 5 bytes of data.
If the

RE-350 receives another kind of data packet which will be described below, the RE-350 will disregard the data

packet and while the RE-350 recognizes the data packet is incorrect, the RE-350 will inactivate the CTS signal line to
the PC.

ID number

Each RE-350 can have an individual ID number, (0,1,2 or 3), which will be set by digital switches 3 and 4 on the rear
panel. The RE-350 will neglect the command data packet which has a different ID number. The PC can recognize
which RE-350 responds.

Parameter

Each data packet has this parameter. If the data packet does not need the parameter, the content should be set by

$0000.

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

2

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

5

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

1

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

2

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

3

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

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-

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 16bit Sample Code (

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).

\16BITSDK)

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.

62

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).

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

3)

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.
