connecting 2 antenna controllers to Simons map

[ve3lbq]

Hello, struggling on connecting Prosistel D controller to show antenna azimuth on Simons map. The controller is connected to PC via USB and creates port. The rest is unclear how to connect to the map. Have been using Yaesu rotator successfully connected already for a while via ERC mini, no problems. Also it would be nice to have my both yaesu and prosistel antenna azimuths showing on the same map. Is that possible? Thanks!
