▪ Special 232C Cable for commercial check Jig
▪ Power only mode
▪ PCB mode (instart menu -> menu -> Configuration Setup
-> RS232 DC Power Outlet )
(2) Check the power out & IR out - commercial check jig
1) Connect each other RS232c port on the Commercial
Check JIG
2) Press RED Color Button on SVC Remote-control in
power only mode (or PCB mode)
3) Check the LED of jig board
- +12V LED (OK condition: Turn On)
- IR LED (OK condition: blinking)
(3) Check the power out & IR out – mini jig
1) Connect mini jig on RS232c port
2) Press RED Color Button on SVC Remote-control in
power only mode (or PCB mode)
3) Check the LED of mini jig
(4) Pro:Idiom Check
1) Connect the RF Cable
2) Turn to the Pro:Idiom channel (No. 333)
3) Check the video & sound
** Only displayed at “POWER ONLY” mode
6. AUDIO output check
6.1. Audio input condition
1) RF input: Mono, 1 KHz sine wave signal, 100 % Modulation

6.2. Specification
7. GND and HI-POT Test
7.1. GND & HI-POT auto-check preparation
(1) Check the POWER CABLE and SIGNAL CABE insertion
condition
7.2. GND & HI-POT auto-check
(1) Pallet moves in the station. (POWER CORD / AV CORD is
tightly inserted)
(2) Connect the AV JACK Tester.
(3) Controller (GWS103-4) on.
(4) GND Test (Auto)
- If Test is failed, Buzzer operates.
- If Test is passed, execute next process (Hi-pot test).
(Remove A/V CORD from A/V JACK BOX)
(5) HI-POT test (Auto)
- If Test is failed, Buzzer operates.
- If Test is passed, GOOD Lamp on and move to next
process automatically.
7.3. Checkpoint
(1) Test voltage
- GND: 1.5KV/min at 100mA
- SIGNAL: 3KV/min at 100mA
(2) TEST time: 1 second
(3) TEST POINT
- GND Test = POWER CORD GND and SIGNAL CABLE
GND.
- Hi-pot Test = POWER CORD GND and LIVE &
NEUTRAL.
(4) LEAKAGE CURRENT: At 0.5 mArms
