13、s 98 version. So some of menu or option name may not be matched with some versions of Windows 98. First of all, User should have the new software file (ROTEL supply) before proceeding the software up-grade process. 1. Power RSX-1055 off. 2. Remove all of connections between RSX-1055 and other equipm

14、ents. 3. Connect RSX-1055 and PC with RJ45/DB9 cable. RJ45 jack should be connected to COMOUTER I/O port in RSX-1055 rear panel. DB9 jack will be connected to PC serial port (ex. COM1 or COM2,). 4. Switch down the SOFTWARE UPGRADABLE key to ON in RSX-1055 rear panel. 5. Open HyperTerminal program in

15、 Windows 98 (Program / Supplement Program / Communication / HyperTerminal) 6. Input name and select icon to use for connection in connection explanation dialogue box and click O.K. 7. Connection object dialogue box appears. Select modem(N) to use for connection. For example, if DB9 cable is connecte

16、d to COM1 serial port of PC, select COM1. 8. Selected serial port registration dialogue box appears. Select value or option per item as follows. *Bit per second (B) : 19200 *Data Bit (D) : 8 *Parity (P) : None *Stop Bit (S) : 1 *Flow Control (F) : None *And click O.K. 9. Click File (F) and click Pro

17、perty (R) in file menu of HyperTerminal. 10. Select setup. 11. In set up dialogue box, select options per item as follows. *Function Key : Terminal Key(T) *Backspace function: Ctr+H(C) *Emulation: VT100 *Telnet Terminal: VT100 *Back scroll buffer line : 500 *And click ASCII Setup (A) *Select (A) & (

Erase of current software begins. 13. When erasing finishes, download file message appears. Select Text file sending (T) in Transmissio

19、n menu (T)of HyperTerminal and text file sending dialogue box appears. 14. Change the finding file format from (*.TXT) to (*.*) format, and find the new software which is for up-date.( *. Bin) format. 15. Double-click new software file. The extension of software file name is bin (ex. xxx.bin). Then

20、software upgrade begins. 16. When the upgrade finishes, check message appears. In the message, compare received data checksum with rom checksum. If they are same, the upgrade is done correctly. 17. Power RSX-1055 off and switch up the SOFTWARE UPGRADABLE key to Off in the rear panel. 18. Disconnect

21、the cable between PC and the RSX-1055 19. Power RSX-1055 on and set the default setting on the OSD screen menu with connecting a TV monitor. And confirm if the software version is upgraded. 1612V-TRIG BDX-1339-04CAPACITOR BDX4002002710X-4002002700POWERTRANSSPKR BDAMP BDE-4002000200TERMINAL B DX-1339
