NexStar SLT mount control

[Snegovik]

Is there any way to control nexstar slt without the remote?
 

Now I do not have a remote and the ability to buy it separately.

Perhaps there is a way to control this mount without the remote control?
I heard something about the rs 232 cable.

The only way I know is to buy the WiFi dongle and you can control it with the Sky Portal app on your phone/tablet. The cable you mentioned plugs into the hand controller if i remember correctly.
