GPI and TALLY intertface

Hello, dear community.
I have a Contstelllation 8k switcher and GPI and TALLY interface.
I am trying to configure tally and GPIO outputs. Is it configurable at all?
I fond only

SET OUTPUTS:
Switcher inputs 1-8
Switcher inputs 9-16
....
Switcher inputs 33-40
.

Does it mean that by this option I choose 8 TALLY/GP Input and Outputs?
I can't find a detailed description of this device and ways of configuration. If someone had experience working with this device, please share your experience.

Best Regards,
Ivan Zabaluyev.

yes .. this interface have 8 tally outputs (hardware relays) .. And this setting is for setup , what inputs U need to send .. for examle .. Constelation have 40 inputs .. so U need 5x TALLY module .. and set outputs on modules :

Switcher inputs 1-8
Switcher inputs 9-16
....
Switcher inputs 33-40
