3) Connection JIG 
4) Check 
=========================================
1. Setting Procedure
1) Setting JIG
(1) Connect UTC-1000 Equipment to JIG device as a like
left picture 
- Connection Line:  
UTC-1000 TOP1 <--> Game port(RJ21) 
-> TV-LINK CFG (Phone Jack)
UTC-1000 TOP2 <--> JIG 11pin Connection 
UTC-1000 RF1  <--> b_LAN RF IN 
UTC-1000 LAN  <--> PC LAN Port 
2. Working procedure
1) Connection
UTC-1000 LAN <--> PC LAN Port 
UTC-1000 TOP1 <--> Game port(RJ21) 
-> TV-LINK CFG (Phone Jack) 
UTC-1000 RF1 <--> b_LAN RF IN 
2) Power on JIG
3) Test Start
UTC-1000 TOP2 <--> JIG 11pin Connection 
4) Checking b-LAN MAC Address
Check whether it is same their address numbers or not
between B-LAN Label and on the pc address
numbers.

2. Check  “Version 6.0” of the 1. b_LAN Application version  
3. Check whether it is same their address numbers or  not between B-LAN Label and  2. MAC Address on the pc. 
12. Default Value in Adjustment mode  
(Default values maybe modified during E/S & L/P Event for adjustment time reduction. But, it will be fixed before Mass Production)
13. Serial number download.
