ARP (Rear Panel)
The LOGIQ™ P5 and LOGIQ™ A5/A5Pro system has the  I/O interfaces for peripherals in rear panel. 
ARP (Arirang Rear Panel) assy has  connectors for peripheral. Composite in/out and S-VHS in/out is for 
the analog video interface for recording and playback  of the VCR or DVD recorder. Audio in/out is for 
audio interface for audio recording and audio playback of the VCR or DVD recorder. The ARP assy also 
has a USB hub device for expending the USB ports  which provide additional USB ports. The analog 
VGA signal also provide display interface for external VGA monitor.

Power Diagrams
5-7-1 Overview
The AC Power assys main tasks are to supply powers the various internal subsystems and to isolate 
electrically the scanner from the on site Mains Power System. The voltage to peripherals can be 
confederated to either 110 VAC or 220 VAC. Internal circuit for AC power have the free voltage 
capability basically but, we should  separate the group using of low voltage (100V~127V), high voltage 
(200V~240V), and mixed voltage (100V~120V for peripheral an d 200V ~ 240V for system). 
5-7-2 TRANSBOX(AC Power)
The mains cord has plugs in one side end. A male plug connects to the mains outlet on site. The mains 
voltage is routed to the Main Circuit Breaker, located on the rear side of the system. The Main Circuit 
Breaker is of the auto fuse type,  if for some reason the current grows to high, the switch will 
automatically break the power. From the Main Circui t Breaker, the AC power is routed via the Mains 
Transformer and the Inrush Current Limiter to in ternal outlet connector for AC distribution.
The Transformer is the galvanic barrier between the re st of the scanner and the on site AC Mains. Input 
voltage to the transformer can be either 220 VAC or  110 VAC. AC output of transformer is supplied to 
the APS/APS Pro through Inrush  Current Limiter without additional co ntrol. AC output of transformer for 
LCDMON, 4D BOX(option),  and peripheral controlled by the L1SYSC ON according to the On/Off status 
of the system.  Figure 5-32   AC Power Assy Block Diagram

5-7-3 APS/APS Pro (LV Power & HV Power)
NOTE: HVL+ and HVL- are  not available for APS PRO.
DC Powers are supplied by APS and sour ce of all assys in nest and nest fan, etc. To turn on the APS, 
the live power is needed as a  standby power. This live power is  generated from APS when the APS 
receive the AC input from the TRANSBOX. When the  LP(live power) is supplied to the L1SYSCON and 
system momentary swit ch is pushed on, L1SYSCON make the LV _ON signal level into low to turn on 
the APS. After turning on the APS, the ACPC in TR ANSBOX assy change the relay path on itself to 
supply stable AC power by using of D12V from APS. 
DC Output Capacity: 
• +D5VLP, 0.42A rms 
•+D5V, 6.5A rms
• +D3.3V, 6.48A rms
• +D12V, 3.36A rms
• +D12VFAN, 0.94A rms
• +A6V, 7.92A rms
• -A6V, 1.52A rms
• +A12V, 1.26A rms
• -A12V, 0.6A rms
APS supplies High Voltage power  to activate high voltage transmit pul se and static supply bias voltage 
on high voltage  mux and probe. When L1S YSCON makes the HV_STOP  signal to low, the APS 
generates the HV module in APS. The SHV supplies +/-80V to the syst em constantly and the THVH and 
THVL supplies 0~+/- 60V individually.
SYSCONPM(SYSCONCM) control the level of TH VH and THVL through the IIC interface.
HV Output Capacity:
• +SHV, +80V, 0.05A rms
• - SHV, -80V, 0.05A rms
• +THVH, 0V~+60V, 0.5A rms
• - THVH, -60V~0V, 0.5A rms
• +THVL, 0V~+60V, 0.5A rms
• - THVL, -60V~0V, 0.5A rms

5-7-4 AC Power Outlet for Peripheral
The ARP CONN ASSY and ARP CONN 220V ASSY are  the ARP assemblies which interconnect 
external signal and power with the LOGIQ™ P5 s ystem. Both of the assemblies are the same except 
the circuit breakers current ratings depending on vo ltage of the system power source (See Safety 
described below).
5-7-4-1 Safety • Circuit Breaker
• Electrical Isolation
The ARPs Insite interface is electr ically isolated from the systems internal circuit. The isolators 
dielectric strength should be 500VAC RMS or higher within 1 minute (in compliance with IEC60601-1-1). Table 5-4    Circuit Breaker Specification

The cable connection can be separated to two group, internal harness and external cable connection 
for peripheral equipment.

The black box with white character is the label of  the connector and the adjacent same label connector 
means that the two connectors should be connected each other. The dotted line means optional 
connection when the customer uses that option. Figure 5-33   Cable Connection - Internal
