I bought a used 497 controller to replace my bricked 494 controller for my ETX-70.
I received it but there is one problem. The controller is in Spanish language, firmware version 42S.
Is there anyway to replace firmware with an English version one, and if yes are there anywhere on the web the firmware files. On the Meade website there is no download info for 497.
I also would like to know about the connection cable for the ETX-70.
I own a 506 cable for the 494 but the 497 is not compatible with the 506. I checked that the 505 cable is something simple enough. Can I use an rj10 to rj10 cable to connect it on the telescope (from one side) and to a rj10 to serial adapter on the other side and then connect to a serial to usb cable I used to use with my 506 cable so I can connect the telescope to my PC?
