トピック： Serial terminal

Serial Interface

Open the Serial Interface and Modem Setup dialog to select the interface type, its mode and to set the parameters of the serial interface.

You can use the serial interface either as signal in-/output for controlling external devices (e.g. alarm bell and light using a relay), for transferring data via a modem or mobile phone or as a web terminal for controlling/monitoring machines.

Note:	This feature is not available for Basic cameras.

Selecting the Operating Mode

Select how would like to use the serial interface in the Operating mode drop-down box:

Operating Mode	Description
Data	The serial interface operates as as terminal or as enhanced signal in-/output
Modem	An analog modem or GSM is used with the serial interface.
Off	The serial interface is deactivated.

Notes:

Depending on the selected operation mode, additional parameters are displayed.
If the serial interface had been deactivated, it will be available only after rebooting the camera.

Data Operating Mode

In the Data operating mode, you can use the camera as web-based data terminal for controlling, monitoring and remotely maintaining machines or to control other devices via the enhanced signal in-/output.

Parameters

Description

Mode

Terminal and Logger Mode

The camera can be used for monitoring and controlling production machines, heating systems and other devices equipped with a serial interface.

Note:
The integrated web terminal is only activated after the camera has been rebooted.

I/O Mode

The three remaining pins are available as signal in-/output. Open the Signal State dialog if you would like to configure this option.

Auto mode

The camera will switch modes depending on the action it is currently executing (e.g. update buffer, set signal output, etc.).

Speed

Select the data transfer speed supported by your modem.

Bits

Number of data bits per character.

Parity

Type of check for a transferred bit sequence:

N	No checks are performed.
E	The sequence is checked for an even number of single bits.
O	The sequence is checked for an odd number of single bits.

Stop Bits

Required number of stop bits

Flow Control

Off	Flow control is deactivated. When you are not sure which type of flow control your modem supports, do not change this setting. The factory default setting is Off.
crtscts	Hardware flow control

Note:	Xon/Xoff are currently not supported.

Echo

Certain devices do not repeat the string that has been sent. For this reason, this string cannot be displayed in the web terminal. Set the Echo parameter to On in order to display the strings sent.

End of Line

The end-of-line character varies between devices. Select the correct character for the device used:

LF	Line feed
CR	Carriage return
LFCR	Line feed/carriage return
CRLF	Carriage return/line feed

Buffer Size

All incoming characters are stored in a buffer prior to being displayed in the web terminal. Set the buffer size (max. 100 kByte).

Timestamp

When you set this parameter to On every line is preceded by a timestamp.

Modem Operating Mode

In the Modem operating mode, the camera can communicate with analog modems or GSM devices in order to establish data connections, for example.

Note:	As modems and GSM devices strongly vary in their use of AT commands, it is recommended that you have the manufacturer's documentation ready when setting the following parameters.

Parameters

Description

Speed

Select the data transfer speed supported by your modem.

Flow Control

Off	Flow control is deactivated. When you are not sure which type of flow control your modem supports, do not change this setting. The factory default setting is Off.
crtscts	Hardware flow control

Note:	Xon/Xoff are currently not supported.

Modem Type

Analog	Analog telephone modem
GSM	GSM model (mobile phone with data transfer, e.g. Siemens MC35, Nokia 30)
Null	Null modem A null modem is a special RS232 cable that has certain pins connected in a manner that a modem connection is simulated. In this cable, certain (at least the send and receive pins) or all pins are cross-connected.

Modem Mode

In	You can dial into the camera using the modem.
Out	The camera can dial out, e.g. for transferring images to the Internet.
In/Out	You can dial into the camera or the camera can dial out.

Note:	Only one channel is available so that dialing in and dialing does not work simultaneously.

Termination Reboot

When you set this parameter to On, the camera will reboot every time after it has dialed out. This means that the internal image storage is deleted and local network connections are interrupted.

Note:	It is recommended to use this setting only when the camera does not send images frequently.

Dial Timeout

The maximum time the camera should wait for a connection to be established.

Modem Init out

Enter the AT commands that your modem needs for initializing an outgoing call. Precede each quote character by a backslash (\").

Modem Init in

Enter the AT commands that your modem needs for initializing an incoming call. Precede each quote character by a backslash (\").

Modem disconnect

Enter the AT commands that your modem needs for terminating a call. Precede each quote character by a backslash (\").

Phone Number

Enter the telephone number that you want the modem to use for dialing out.

Dial Mode

Tone	The selected numbers are transferred as tones. This is the factory default setting.
Pulse	The selected numbers are transferred as pulses. This is an old-fashioned method.
No	The dialing method preset by the manufacturer is used.

IP Address Camera

The IP address used by the camera. When you do not enter an IP address, the factory default IP address is used.

IP Address Peer

The IP address that is assigned to the device dialing in. When you do not enter an IP address, the factory-preset IP address (172.16.23.202) is used.

IP Address Outgoing Gateway

When having dialed out successfully, the called device transmits the IP address of the gateway. The IP address entered here must not be identical to either the camera's IP address or a local address. When you do not enter an IP address, the factory-preset IP address (172.16.23.202) is used.

Authentication

Select the authentication protocol of your choice to be used when establishing a connection. Other than PAP, CHAP encodes the user name and password prior to transfer. The factory default setting is PAP.

Note:	Both parties need to use the same protocol.

Camera Login

User name and password used to dial into the camera. Enter the password twice.

Remote Login

User name and password used by the camera for dialing out. Enter the password twice.

Idle Time

When no data traffic is recognized for the period of time set here, the camera terminates the connection.

Echo Interval

Period of time after which the camera checks whether the connection has been interrupted.
Recommended value: 10 seconds.

Echo Fails

Number of retries checking for interruptions. The connection is terminated when the selected value has been reached.

PIN code for using the GSM card. When no PIN is necessary, leave this box empty.

Warning:	Entering an invalid PIN may result in a locked GSM card!

PIN delay

Period of time that the camera waits after the PIN has been entered.
Recommended value: 15 seconds.

Store the Configuration

Click on the Set button to activate your settings and to save them until the camera is rebooted.

Click on the Close button to close the dialog. While closing the dialog, the system checks the entire configuration for changes. If changes are detected, you will be asked if you would like to store the entire configuration permanently.
