- System control RS-232 Host should be “PC” for adjustment.

Refer to the “6.1.2 Procedure of Adjustment” and adjust
three items of ADC on PCB Ass’y level through the RS-
232C.

** ADC adjustment RS232C Protocol Ver 1.0

* Baud Rate : 115,200 bps
* RS232C Host : PC
* echo : None

(1) Requirement for Adjustment

- Pattern Generator : MSPG-925FA
- Adjust 480i Comp1(Model : 209, Pattern : 65)
- Adjust 1080p Comp1 / RGB(Model : 225, Pattern : 65)

(2) Adjustment Procedure

- ad 00 00  Entering ADC Adjustment Mode
- kb 00 04  Component1 Input Change
- ad 00 10  Adjust 480i Comp1
- kb 00 06  RGB-DTV Input Change
- ad 00 10  Adjust 1080p Comp1/RGB
- ad 00 90  Finish adjustment

For downloading the MAC address which be allotted on each
LAN Card.

(1) Adjustment Method

1) Connecting the TV set and the PC which has MAC

Address Writing program through the RS232C cable.

2) Editing the mac address.txt

(Inserting start MAC address at top low.

Inserting start MAC address at bottom low.
Launch MAC Address Writing program and set just like
below picture. - (1)

3) Click the LOAD button for reading the MAC address.- (2)

(SAVE : Saving the current MAC Address

CLEAR : Initializing the space which insert MAC Address.

4) Click the “MAC Address writing” button to write current

MAC Address.- (3)

5) In case of being downloaded normally, you can see the

“OK” message in the window. - (4)

6) In case of being downloaded normally, MAC address

increased one by one automatically. So the next set, just
click the “MAC Address writing” button after connecting
the port.

(Whenever be finished, the program saves the MAC
Address in “mac address.txt” file automatically.)

* For confirm works normally the LAN card through PING TEST.

(1) Adjustment Method (PCB Ass’y Level)

1) Connecting the LAN to Ass’y and then turn on the Power.

(Default IP Setting is “Automatic setting” and allocated
the IP from Router each Power ON time automatically.)

2) Press the ADJ Key in the adjustment remote controller.
3) Press the “11. ACAP PING TEST” in EZ ADJUST menu

to check the Network works well. 

In case of normal status, you can see the “Network is
normal” message. 
And abnormal case, you can see “Network is not normal”
message.
