Relay Firmware Question

I would like to try and save myself some money by buying some DIN Relay units from Ebay but obviously I won't know what firmware versions I may get.

Can someone shed some light on where the intelligence resides please ?

Would I be correct to assume that the relay units are pretty 'dumb' (apologies to whoever spent his working hours writing the relay firmware ) so it won't matter how old the relay units are as they just switch on or off when instructed, and it is the switches and other input units that contain the intelligent firmware ?

Are there any firmware versions that introduced new features or cured significant bugs from early versions that I should aim for ?

Or am I barking up the wrong tree with the idea that the relays are 'dumb' ?

Any info gratefully received.

Thanks

From the first firmware released for DIN C-Bus relays have had similar features:

adjustable turn-on threshold
Logic capability with other groups in the unit
configurable power-up state
restrike timers for use with HID lighting

Later firmware includes a few new 'system' features to speed-up communications and respond to some system maintenance commands, but none of these changes would affect operation of the relay functions.

Learn mode was changed in V 1.4.00 to allow a channel to retain its prior programmed group through a learn session. This would only be of interest if you are not using Toolkit to configure the unit.

There have been a few minor bug fixes as well.. none of which affect normal operation, apart from a slight improvement in performance when network communications are marginal.

 

Thanks very much guys for the answers - just what I wanted to know.

Cheers
