This version of TallyMan contains drivers and features that are only supported in MK2 system controllers (TM1 MK2 and TM1+ MK2),
these are easily identified as they have a screen on the front panel whereas MK1 controllers (TM1,TM2,TM2+) do not have a screen.

This version of TallyMan requires that the TM MK2 be running firmware version 1.6.04 or above, please contact support@tslproducts.com
if your MK2 system controller has older firmware.
