34s cable?

[BarryT]

Hi all,
. I recently acquired a 20b to re-purpose into a 34s and was wondering if anyone could confirm whether a cable such as THIS ONE would be adequate for flashing it? Obviously I'd need to make the end connect up properly with 20b, but just wondering if the cable itself will do the trick, or, if something else is necessary?

If I've been reading posts and articles correctly, this ought to work, but thought I'd confirm with the many fine folks here who know for certain.

Thanks all.
