remote commands

Hi, Our club is operating a hytera rd985 as a 2m repeater. it’s up a hill with no internet connection. What’s the simplest way to connect to it remotely and change setting in the cps? Thanks Angus

Is there an updated listing on the 4/536HP remote commands? The existing one (1.03) seems to be missing the KEY codes, etc. I did get an update on one new command (MSM) from Upman. Thank you all !! John
