Features

10369 interface board is an extension board for the Elphel 353/363 series cameras.

• It provides multiple interfaces and peripherals to the camera:
  • SATA port for external disk drives
  • Compact Flash (in "True IDE" mode) and IDE HDD ports (with adapter/riser boards: 103691, 103692)
  • RS-232 port
  • Opto-isolated I/O port for synchronizing the camera or synchronizing together multiple cameras (modular RJ14 external connector)
  • Opto-isolated I/O port for synchronizing multiple camera modules in the same enclosure (flex cable connectors)
  • Digital thermometer with internal ("system") and external thermal sensor (emitter-base junction of PNP or NPN transistor)
  • Fan driver, controlled by the digital thermometer with programmable on/off temperature
  • Clock/calendar with the super-capacitor backup power
  • EEPROM for the board identification and configuration

Adapters

10369 board is used with several adapters:

• 103691 - adapter/riser to connect one or two Compact Flash cards
• 103692 - adapter for the ZIF-type (flex cable connector) 1.8" HDD
• 103693 - USB type A (host) connecor adapter mounted on the back panel of the Elphel Model 353 camera.

On-board I2C devices

Remote/local digital temperature sensor

The temperature sensor measures on-chip ("system") temperature, it can also measure temperature of the additional sensor (small transistor) soldered to the pads W2-W3. Additionally this circuit can automatically control 3.3V/5.0V fan (if connected to J17) - in that case the pins W2-W3 should be soldered together if external sensor is not used).

Manufacturer - NXP Semiconductors

Datasheet - SA56004X_5.pdf

I2C slave address: 0x90

Example - reading register 0 (LTHB : Local Temperature High Byte):

http://192.168.0.9/i2c.php?width=8&bus=1&adr=0x4800 // Add register number to the base address of 0x4800

Returns xml file that includes the temperature register (signed char, °C), +48°C in the example below:

<?xml version="1.0"?>
<i2c>
 <width>8</width>
 <bus>1</bus>
 <slave>0x90</slave>
 <adr>18432</adr>
 <hex_adr>0x4800</hex_adr>
 <data>48</data>
 <rdata>48</rdata>
 <hex_data>0x30</hex_data>
</i2c>

Clock/calendar

10369 has on-board clock/calendar with the backup power provided by the supercapacitor (1.0F x 2.5V) - it should enable clock to run for several weeks if the camera is left without power.

Manufacturer - NXP Semiconductors

Datasheet - PCF8563_6.pdf

I2C slave address: 0xa2

Example - reading register 2 (seconds):

http://192.168.0.9/i2c.php?width=8&bus=1&adr=0x5102 // Add register number to the base address of 0x5100

Returns xml file that includes seconds portion of the current time - 54sec in the example below:

<?xml version="1.0"?>
<i2c>
 <width>8</width>
 <bus>1</bus>
 <slave>0xa2</slave>
 <adr>20738</adr>
 <hex_adr>0x5102</hex_adr>
 <data>54</data>
 <rdata>54</rdata>
 <hex_data>0x36</hex_data>
</i2c>

Example - setting camera system time to the clock/calendar time:

http://192.168.0.9/i2c.php?cmd=fromCMOS

If the clock calendar contains valid date/time, it returns xml file like following:

<i2c>
<result>
 "System clock is set to Tue Jul  1 01:01:53 UTC 2008"
</result>
</i2c>

Otherwise (time is not set or the capacitor ran out of charge):

<i2c>
<result>
 "Set system time error (probably CMOS clock is not set)"
</result>
</i2c>

In that case the clock/calendar should be set. First - set the system clock (i.e. open camera web interface, it will set the camera system time to that of the computer), then open

http://192.168.0.9/i2c.php?cmd=toCMOS

The resulty should be just:

<i2c>
<result>OK</result>
</i2c>

Connectors

J1 - AUX (from the CPU board)

J2 - IDE (from the CPU board)

J3 - Power (from the CPU board)

Note: +/- 48V are non-regulated input power rails. For 12V or 24V camera modifications these lines will also have +/-12V or +/-24V.

J4 - Power (optional - to the next boards)

Note: J4 is normally not installed. It is used in some camera modificatios where ther is another board on top of the 10369 that needs power - J4 is located oppposite to J3, same as on 10353 system board.

J5 - Power (optional 3.3V in)

Note: J5 is normally not installed. It may be used in multi-camera systems to provide 3.3V from the commomn to all camera modules power supply (DC-DC converter on 10353 should not be installed).

J6 - IDE (to adapter/riser)

J7 - SATA

J8 - USB0 (to external)

J9 - USB1 (to internal)

J10 - USB2 (to internal)

J11 - USB4 (to internal)

J12 - SYNC (internal, master)

Note: Connect J12 to J14 on the next camera in chain with a 4-conductor flex jumper, then from J13 of that next camera to the next in chain's J14, and so on. J12 and J13 have contacts on the bottom side, J14 - on the top to simplify chaining.

J13 - SYNC (internal, slave)

Note: Connect J12 to J14 of the next camera module in chain.

J14 - SYNC (internal, slave)

Note: Connect J14 to J13 of the previous camera module in chain (if the previous is not the master). If it is the master, connect J14 to the master's J12 instead of the J13

J15 - SYNC (external)

Note: In order to synchronize multiple cameras connect the pins 2 on all cameras together, same for all the pins 3. Additionally connect pin 1 on the 'master' (synchronization source) camera to pin 3, pin 4 - with pin2.

J16 - RS-232

J17 - Fan

Note: Default configuration supports 3.3VDC fans, in order to switch to 5.0V you need to open (cut trace) jumper JP2 and close (solder together terminals of) jumper JP1.

W2-W4 - Terminals for external temperature sensor

Note: small NPN (i.e. 2N3904) or PNP (i.e. 2N3906) can be used as an external sensor. Connect NPN base (or PNP emitter) to W2, NPN emitter (or PNP base) to W3 (W4 may be connected to the shield around these two wires that shoul be twisted). If no sensor is used W2 and W3 should be connected together to enable fan control.
