Sensor input expander

[Bikey]

Any pre-release details that you can share on this, including an ETA?

Thanks.

The Analog 8 expander looks good and the price is reasonable, thanks.
A few questions
1 - how would the Analog 8 be integrated into a Dash/Vid4/DL1 Mk3 setup?
2 - On a DL1 Mk3 with dual serial ports - the data from an Analog 8 can be sent over Serial 2 (which can only receive), correct? Any idea how many Analog 8 modules the Serial 2 bus will support with channels logged at 100/50/25 or 10hz?
3 - Is there anyway to upgrade the g sensor in the Analog 8 from 2g to 6g?

Thanks.

Hi there

1. The most elegant solution would be to connect it to the
DL1 second serial port, with a breakout cable and appropriate licence (the former being included in the price of the latter)

2. At 115200 you get 11 520 bytes per second, 5 bytes per message so a maximum of 2304 messages / second.
In practice we don't like to go much over 50% bus capacity., so at 100Hz the 8 channels would use a maximum of about half of the recommended capacity.
It only sends the data if the input value changes though, so in practice it is much less than this.

3. The sensor cannot be upgraded to 6g.

Hope this helps.

Great, thank you.

Hi there,

A few questions regarding the analogue expander module:-

1) That is the resolution of the input channels? 0-16V is quite a useable range, but can limit the resolution of low voltage sensors if it's 12 bit.

2) What is the safe overvoltage range of the inputs?

3) Does it sample each channel sequentially within each sample step taken?

Looking forward to getting one of these; should be compatible with DL1 Mk2 right? Maybe with a firmware update?

Also, probably needs a y-harness to also support Dash3 from the same DL1?

Hi There,

Yes the module is indeed compatible with a DL1 Mk2, Simply make sure you have the latest version of firmware installed on the unit.

No need for the Y-Cable, the DASH3 will connect directly to a specific DASH connection called "Serial Data in" on the Analogue Module.

Kind Regards.

Hi There,

1 - Resolution on each channel is to 3 decimal places.

2 - 16v is the maximum voltage.

3 - Yes, I believe this to be the case.
