RSX-1055 Setting
- AM Frequency : 603KHz (or 600KHz)
1. Turn AM Signal Generator Modulation ON
2. Adjust RSX-1055 AM Freq. to 603KHz (or 600KHz) and measure output level with Audio Signal analyzer.
3. If it is lower than 200mV , Adjust output level to maximum point with RF BLOCK BLACK COIL ( AM-ANT ).
( recommand higher than 250mV )
4. Set Generator' RF & RSX1055's RF to 999kHz(or 1000kHz) and measure output level with Audio Signal analyzer.
Adjust output level to maximum point with IF BLOCK YELLOW COIL
(C) TUNED Level adjust
AM Signal Generator Setting
- Modulation : 30% - Audio Frequency : 400Hz - Radio Frequency : 999KHz (or 1000KHZ)
- Output Level : 84dB
RSX-1055 Setting
- AM Frequency : 999KHz (or 1000KHz)
1. Turn AM Signal Generator Modulation ON ( Make sure if Output level is 84dB )
2. If 'TUNED' indicator does not turn on at higher than 80~86dB(Generator output),
Adjust SVR01 ( AM-ADJ ) up to the moment where 'TUNED' indicator tunrs OFF & ON again
3. Confirm if 'TUNED' turns OFF when decreasing the output level of AM Signal Generator slowly from 84dB to 80dB.
4. Push RSX-1055 TUNE UP or DOWN button "long" at AM Signal Generator Output Level 84dB and start AUTO search.
Confirm if search stops at AM Frequency 999KHz (or 1000KHz).
< Check with both of High Freq. -> 999KHz(or 1000KHz) search , Low Freq. -> 999KHz(or 1000KHz) search >

Procedure of RSX-1055 software upgrade
*Note : This procedure is made by translation of Windows 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 equipments.
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 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 connected 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 Property (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) & (W) at ASCII receiving section, Click O.K
*Click O.K
12. Power RSX-1055 on and then options message appears in HyperTerminal screen. In the
message, select number 1. Erase of current software begins.
13. When erasing finishes, download file message appears. Select Text file sending (T) in
Transmission 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
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 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.
