multiple repeater mean s hub ;        
8 ( 2 , 4 ) roll over cable ;
            - color pin ;
always blue , always flat ;        
one side is RJ45 , other side is DB9  
( adapter cable ) to USB 2 ;    
console port only ;            
console mean s no routing , no switching ;

            - color pin ;
      - white - brown - brown ;
      - white - orange - blue ;
      - white - blue - orange ;
      - white - green - green ;

straight through cable:

- pin order is left to right;
- white-orange-orange (1st pair);
- white-green-blue (2nd pair);
- white-blue-green (3rd pair);
- white-brown-brown (4th pair);
- two ends must have same the same order to be straight through cable;
- if NOT having the same order (two ends), then it is called crossover cable;
- good for routing & switching;
- switch to router (straight through cable);

rollover cable:

- rollover cable is blue (RJ45, DB9 RS232);
- DB9 to USB2 if USB connectivity;
- using for configuration, maintenance, and trouble shooting only;
- WHICH means no routing, no switching;
- console port only, regarding rollover cable;

crossover cable:

- white-green-green (1st pair);
- white-orange-blue (2nd pair);
- white-blue-orange (3rd pair);
- white-brown-brown (4th pair);
- good for routing & switching;
- since two ends are in different order, therefore, it cannot be straight through, so called crossover cable;

Remark: 4 kinds of cables are crossover cable, rollover cable, serial cable, and straight through cable, and the cable (networking) information is lectured by Mr. Naing Kyaw, Ithaca High School (New York), Bachelor's of Business Administration (BBA), Master of Information System / Management (MIS/M), Cisco Certified Network Associate (CCNA, 2019); completed CCNP training; Naing (Nigel) Kyaw has been a faculty of Touro College (a non-profit organization, ) in New York, USA, for 8 years already, as of 2018/2562; he has been very busy with fully booked students and his own lab equipments, regarding computer, English, math, ... ; "quiet a little port" would be a phrase (keywords), and "responsible with IT" would be an answer ... ;

Mainline Branch, consider the above diagram, Notebook Computer 4 is SHARP notebook, a developer's stand alone computer which has been deployed as non Internet/Intranet computer, and Notebook Computer 3 is SONY notebook, a developer's Internet/Intranet connectivity computer via a gateway router for uploading contents, and Notebook Computer 4 has been stand alone, which means it has not been connected by neither wire nor wireless; After directories and files transferring via USB Flash Drive [one way only, also see: schematic, the most and the highest system security method for any developing domain], and after WRITE cd-r, dvd+r, SHARP notebook system i.e. 4 and SONY notebook system i.e. 3 know each other internally a.k.a. "Mainline Branch", therefore robotic crawler only know such number as Mainline Branch, and it is the most and the highest security to any system in developing/engineering/research, therefore in this system architecture, Notebook Computer 4 is Mainline Branch, Notebook Computer 3 is a Proxy "agent" to 4;
