GPIO is shown on Fig.1. Figure 1. Example of GPIO connections. An example of connecting 2453's GPIO is shown on Fig.1. The optoisolators are Avago ACPL-217. Please refer to the manufacturer's documentation for complete electrical specifications. -
Page 9: Configuration Switches
Configuration Switches A block of DIP switches allows configuration of 2453's serial interface. Individual switch numbers and On/Off positions are indicated on the block. The interface can be configured for RS-232, RS-422 or RS-485 modes. Additionally a 120 Ohm termination can be turned on or off on RS-422/485 receive and transmit lines individually. -
Page 10: Web Page Interface
Web page interface Main menu Main Menu is the default screen displayed when the browser connects to the 2453. The default IP address as shipped is 192.168.24.53. Connect to the board by typing this address in the browser address bar. -
Page 11: Live Stream View
Live stream view windows display the live view of one of the two streams available from the 2453. To access the window click on one of the links (Live View/Stream A or Live View/Stream B) in the navigation bar. Streams are configured as described below in sections “Stream Controls”... -
Page 12: Rtsp Streams
RTSP streams Live View / RTSP Streams page provides a list of rtsp:// URLs which can be viewed using VLC or another RTSP-compatible player. The player is responsible for requesting the video and starting and stopping the stream. Right click on the link that corresponds to current configuration of selected stream (A or B), copy link address, and paste it into the player's stream address field, as shown below for VLC. -
Page 13: Stream Control
Sequencing: if on, a 2 byte sequence counter is sent with each packet. That could be used by the software on the receiving end to detect network packet loss. Startup: if set to On, the stream will start automatically when the 2453 is powered up. -
Page 14: Recording Control
Recorded file can be split into segments, in which case duration (maximum size) applies to each segment. Recording requires a 2453TA board with an SD card to be connected to the 2453. -
Page 15: Stream Configuration
Stream Configuration Stream configuration window allows configuring individual stream parameters which may differ between streams A and B. Format: allows selection of compression (H.264, MPEG4 or MJPEG) and stream types (video elementary stream, VES; MPEG transport stream, MPEG-TS, with or without AAC audio). - Page 16 OSD (on screen display): allows putting an optional text overlay (caption) on top of video (up to 160 characters). Standard formatting functions allow automatic insertion of date, time and some other information into the caption. Message field allows setting the caption text . The following formatting codes are supported: ^d –...

Page 17: Stream Configuration - Video
Stream Configuration - Video Stream Configuration – Video window allows configuration of video parameters common to both streams A and B. Video standard: NTSC or PAL. Field mode: interlaced or interpolated. This setting is relevant for full frame resolutions (480 or 576 lines). Interlaced mode preserves both video fields, resulting in highest vertical resolution, but possible motion artifacts. -
Page 18: Stream Configuration - Audio
Stream Configuration - Audio Audio parameters control input source (line or microphone), sampling rate, volume (input and output), and some other settings. Audio parameters are common to both streams A and B. An online help in the right section of the web page contains details. -
Page 19: Clock Configuration
Clock Configuration The Clock Configuration page allows setting the 2453 internal clock either manually (using a 24- hour format), or to the host's time. With a battery installed on the optional 2453TA board the 2453 will keep time when powered down. -
Page 20: Network Configuration
LAN using an Ethernet patch cable, Cat5 or better. The 2453 automatically detects the type of the host interface, so it can be connected both to the computer and to a switch (hub) using the same type of cable. -
Page 21: Step 1 - Setting Up A Temporary Ip Address
Now switch the 2453 into the Configuration Mode by pressing the configuration button. The red LED starts blinking. Note: you need to wait 15 seconds after the 2453 is powered up before the board is able to switch to Configuration Mode. -
Page 22: Step 2 - Setting Up A Permanent Ip Address
Step 2 – Setting up a permanent IP address Connect to the unit with a Web browser by typing the unit's temporary IP address in the address field. Example: http://10.135.1.61 Once the Main Menu page is displayed, select Admin/Network. Type in the desired permanent IP address and subnet mask values into corresponding fields. -
Page 23: User Management
User management User Management window allows access to the device to be limited to certain users with an associated permission level. The permissions levels are: None (guest user only); • Stream View (may only access live view or RTSP streams); •... - Page 24 To create a new user, enter the user name and password, select the desired permission level and then click Create User. Both user name and password are case-sensitive. The password “password” is not allowed.

Page 25: Firmware Update
The Firmware Update window displays the versions of the device's firmware components and the serial number. To update the firmware, choose the file (s2453.fw provided by Sensoray) and press Submit. The firmware update should take about 30 seconds to complete. Do not unplug the device while the firmware update is in process. -
