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) connector adapter mounted on the back panel of the Elphel Model 353 camera.
RJ45/DB9F_Modular_Adapter - DB9F to RJ45/RJ25 modular adapter

On-board I2C devices

8-bit port/EEPROM

This combined port/EEPROM chip for the board identification and it also controls some IDE-related parameters of the board.

Manufacturer - NXP Semiconductors
Datasheet - PCA9500_3.pdf
I2C slave addresses:
- 8-bit port: 0x40
- EEPROM: 0xa0

8-bit port

The 8-bit port is bidirectional with weak pull up (strong pull up during write pulse), so to work as input bit has to be programmed with "1". There is a single "register" that corresponds to I/O bits that does not have any address, so a raw mode is used during I2C read/write. Default value after power up is 0xff (all bits "1").

Note: rebooting the camera does not reset the port - values are preserved.

I2C control port bits
bit	Direction	Signal	Notes
0	INPUT	CF0PRESENT	pulled to "0" by the CF0 (bottom, master) card if it is installed (otherwise returns "1")
1	INPUT	CF1PRESENT	pulled to "0" by the CF1 (top, slave) card if it is installed (otherwise returns "1")
2	OUTPUT	EN_CFM	enable CF0 (master). If set to "0" the CF0 card is reset (gives way to SATA)
3	OUTPUT	EN_CFS	enable CF1 (slave). If set to "0" the CF1 card is reset (gives way to SATA)
4	OUTPUT	EN_SATA	enable SATA port. If set to "0" the SATA port is reset (gives way to CF)
5	OUTPUT	SATA_MASTER	if set to "0" SATA will be slave IDE device, with "1" (default) it is IDE master
6	OUTPUT	DIS_SPREAD	disable spread spectrum in SATA (default). If set to "0" the SATA uses spread spectrum
7	BIDIR	GPIO7	reserved, connected to W1 solder point

Example - reading status of CF cards installed):

http://192.168.0.73/i2c.php?bus=1&raw=0x2000

result (CF0 present, CF1 - not installed, outputs - default):

<?xml version="1.0"?>
<i2c>
 <width>8</width>
 <bus>1</bus>
 <slave>0x40</slave>
 <data>254</data>
 <rdata>254</rdata>
 <hex_data>0xfe</hex_data>
</i2c>

Example - setting SATA to be IDE slave (needed if bottom CF card is installed):

http://192.168.0.73/i2c.php?bus=1&raw=0x2000&data=0xdf

then reboot (not power cycle) the camera - the SATA disk will be IDE slave, CF0 - IDE master

Identification EEPROM

Example - reading EEPROM data (it stores up to 256 bytes, containing text xml data):

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

Result:

<?xml version="1.0" standalone="yes"?>
<board>
 <brand>Elphel</brand>

 <serial>000101</serial>

</board>

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. The same 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 CMOS 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.

Example - read CMOS clock/calendar time:

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

Work in the same way as "fromCMOS" but without modification of camera system time.

Example - setting the clock/calendar

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 result should be just:

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