"The use of usb to transfer operational data between receivers is a great function I've never used, but would if it would help in what I'm doing."
It is the only way to keep your fav lists and audio settings as a copy too. Like setting a restore point for your computer; or backing up files you have on a hard drive. The usb2 plug can even format drives you want to use to have recorded programs to refer to.
I use my little flash drives alot with the 1200 recvr. for the pvr too. They allow me to control what the receiver is doing at any one time. I make up lists for people; as time goes the people give their lists; or have the list they use; to make their tv better. That is a customization; like having a camper mirror for the pickup.
The auto-update is this function (data for receiver) over the G19 satellite; and when it does put new data into the hdvr1200, you are assured by Glorystar that it is needed and works already. This is a greater thing also; as it is a powerful tool for them to use to help their system work better. This auto-update part of their receiver's is very high tech. It works in advanced mode also; and when you have the G19 satellite scanned, it does update via satellite, no phone or internet required. This is a great achievement of Glorystar, and will always be used for exactly what you are talking about. Adding channels!
Channels, on G19 have been coming and going for years now. Since the number of FTA channels hit 200+ via G19; the churn of channels has been non-stop; so goes the day of a satellite channels life. Only the viewers of them have anything said; as the programming and requirements to be in the Broadcast Industry here in the US are the easiest to Broadcast in. Because the audience is religion; and multi-denominational, here is G19 with every channel. And putting the hdvr1200 receiver in non-glorystar mode (advanced) is required to see the rest of G19. A channel list allows you to this readily; and you can clone and make up the list you want to show on your receiver; they just must be scanned channels on any hdvr1200 anywhere (like at glorystar)!
Using usb2 ports is dangerous if not used correctly; this means that if you plug something into your machine, not to touch the plug again until all data has been written to/from your usb2 flash or hard drive. Unplugging it requires care that the usb2 port was not being used when you do. Otherwise, this port, plug; will/can/has/will again have the chance to break a hard drive or thumb drive. Care in data management does allow anybody to keep this "files" and handling it (the data) requires care and a step by step approach, as you know it is yours to use to perform the duty; just for a certain channel, or operational flash re-write, the hdvr1200 dvb-s2 receiver/media box has many uses for its usb2 port. And it requires multiple type usb2 devices; like hard drives and flash memory sticks. So, use of the usb2 port is needed when using the hdvr1200 from glorystar when recording or "tivo-ing".
Two receiver "cloning" - making the 2nd receiver have the same everything just like the first (i use usb2 flash drive; and put it onto the second receiver of the same exact type and brand) Glorystar GeosatPro hdvr1200 ONLY.
