TVI I300 Hardware Manual © Essential Viewing Systems Limited 2010 3 Mechanical Dimensions The TVI I300 PCB is 120mm long by 145mm wide by 1.6mm deep. The board incorporates six M3 sized grounded holes to support mounting of the board within an enclosure. The mounting points are specified by the following diagram where all dimensions are in mm and the view is of the top side of the board.
TVI I300 Hardware Manual © Essential Viewing Systems Limited 2010 4 TVI I300 Board Connectors The I300 board has been designed for mounting within an enclosure where connectivity to either a companion board or to bulkhead connectors is achieved via flying leads to board mount headers. The following diagram illustrates the layout and location of the I300 headers and connectors where these are prefixed by a “J” code on the PCB.
TVI I300 Hardware Manual © Essential Viewing Systems Limited 2010 4.1 Connector Parts The following parts are required for connection to the I300 board. Note that wires must not be soldered directly to any pins on the board.
TVI I300 Hardware Manual © Essential Viewing Systems Limited 2010 4.2 Cellular RF Antenna – J9 The I300 includes an onboard cellular modem which requires an external RF antenna to operate. The antenna connector on the I300 is an SMA socket labelled as J9. The connection from J9 to the external antenna must be via coax with a 50 ohm per meter impendence.
TVI I300 Hardware Manual © Essential Viewing Systems Limited 2010 4.5 RS422/RS485 & Triggers – J24 The I300 provides a configurable RS422/RS485 port together with three isolated trigger inputs on header J24. Each of the triggers is activated by applying an external voltage across the trigger input and the trigger ground. The following table specifies the mating connector and connector pins.
TVI I300 Hardware Manual © Essential Viewing Systems Limited 2010 4.7 Synchronous RS232 – J26 The I300 provides an RS232 port for synchronous serial communications with devices generating a clock signal via header J26. The following table specifies the mating connector and connector pins. J26 – 5x2 JST PHD connector Description Pin TxD 1 RxD 2 RTS 3 CTS 4 DCD 5 CLOCK 6 DTR 7 GND 8 9 10 4.
TVI I300 Hardware Manual © Essential Viewing Systems Limited 2010 4.9 Status LEDs – J31 & J32 The operational status reporting of the I300 is provided via five common cathode tri-state LEDs where each should nominally be capable of illuminating as red, green, or orange (red plus green).
TVI I300 Hardware Manual © Essential Viewing Systems Limited 2010 4.10 Video Output – J34 The I300 provides a single video output via a 75 ohm mini SMB connector on J34. Note that the connection from the board to the bulkhead connector must be 75 ohm coax cable and it is recommended that a 75 ohm BNC bulkhead connector is used as illustrated below.
TVI I300 Hardware Manual © Essential Viewing Systems Limited 2010 4.12 External SIM – J38 The I300 provides both a PCB mounted SIM carrier (J13) and a header supporting operation with a bulkhead mounted SIM via J38. Note that only one SIM can be utilised. The following table specifies the mating connector and connector pins. J38 – 4x2 JST PHDR connector Description Pin SIM Power (Vcc) 1 SIM Data I/O 2 SIM Reset 3 SIM Inserted 4 SIM Clock 5 N/C 6 Chassis GND 7 Power GND 8 4.
TVI I300 Hardware Manual © Essential Viewing Systems Limited 2010 5 Factory Configuration The standard mechanism for installing firmware and for configuring the operational mode of an I300 is via a USB mass storage device. The I300 uses non volatile memory to store firmware and configuration where the configuration partition includes both factory settings and user definable settings.
TVI I300 Hardware Manual © Essential Viewing Systems Limited 2010 5.2 Factory Reset It is possible to remove the configuration settings of an I300 and restore the unit back to the ‘original factory defaults’. This operation does not remove any OEM Defaults that have been applied and so the I300 will retain any OEM Default settings applied. This operation is designed to be used by an end-user who wishes to reset their I300.
TVI I300 Hardware Manual © Essential Viewing Systems Limited 2010 Cellular Operation The choice of external antenna will depend on operational factors and on the frequency bands used by the selected network.
TVI I300 Hardware Manual © Essential Viewing Systems Limited 2010 6 Safety Recommendations The I300 board contains ESD (electrostatic discharge) sensitive devices. Electrostatic charges readily accumulate on the human body and equipment where discharge can occur without detection. Permanent damage may occur on devices subjected to high energy discharges. Proper ESD precautions are recommended to avoid performance degradation or loss of functionality. Store any unused I300 boards in anti-static packaging.
