OCG-D power consumption?

[Jan Zavitski]

Hello all,

I have searched through the forum and still have a couple of unanswered questions regarding the OCG-D (model MTCDP-G2-1.0 to be precise):

1. What are the typical power consumptions of the device (while being idle, transmitting/receiving data via 2G, etc)?

2. Does it support any low-power modes?

3. According to the specification it has an ARM9 CPU – can anybody specify an exact make?

4. Is it shipped with a schematic?

Regards,

Jan Zavitski

Hi,

1. What are the typical power consumptions of the device (while being idle, transmitting/receiving data via 2G, etc)?

Answer:

http://www.multitech.net/developer/products/multiconnect-ocg/hardware/multiconnect-ocg-d/hardware-specifications-r1-0/

2. Does it support any low-power modes?

Answer:

Yes. standby and mem mode.

Ex:

An example of how to put your MT100EOCG/MTCDP in a standby mode and wake it up using the serial port console (ttyS0).

*Plug in your 3pin debug cable and at the prompt type:

echo enabled > /sys/devices/platform/atmel_usart.0/tty/ttyS0/power/wakeup[Enter]

*Enable ttyS0 port to wake up.

echo standby > /sys/power/state[Enter]

*Put the processor in stand by mode.

Now, you can just hit a space bar or Enter key to wake it up.

Another example, you can wake up using the rtc timer by typing at the prompt:

echo “” > /sys/devices/platform/at91_rtt.0/rtc/rtc0/wakealarm[Enter]

*Clear the value.

echo “+30” > /sys/devices/platform/at91_rtt.0/rtc/rtc0/wakealarm[Enter]

echo mem > /sys/power/state[Enter]

*Put the processor in “mem” mode.

*Now, the device will wake up after the timer is expired (30secs).

3. According to the specification it has an ARM9 CPU – can anybody specify an exact make?

Answer:

AT91SAM9G20-CU

4. Is it shipped with a schematic?

Answer:

No.
