2. ANSI/TIA-568 - Wikipedia

   en.wikipedia.org/wiki/ANSI/TIA-568

   A cable terminated according to T568A on one end and T568B on the other is a crossover cable when used with the earlier twisted-pair Ethernet standards that use only two of the pairs because the pairs used happen to be pairs 2 and 3, the same pairs on which T568A and T568B differ. Crossover cables are occasionally needed for 10BASE-T and ...

3. Modular connector - Wikipedia

   en.wikipedia.org/wiki/Modular_connector

   Only lines 1 and 2 have electrical compatibility, with T568A wiring, and only line 1 with T568B wiring, because Ethernet-compatible pin assignments split the third pair of RJ25 across two separate cable pairs, rendering that pair unusable by an analog phone. (With T568B wiring, a telephone may connect to line 3 as line 2.) Both the third and ...

4. Ethernet over twisted pair - Wikipedia

   en.wikipedia.org/wiki/Ethernet_over_twisted_pair

   IEC 63171-6 industrial: [6] This standard defines five 2-pin connectors that differ in their locking mechanisms, and one 4-pin connector with dedicated pins for power. The locking mechanisms range from a metal locking tab to M8 and M12 connectors with screw or push-pull locking. The 4-pin connector is only defined with M8 screw locking.

5. 25-pair color code - Wikipedia

   en.wikipedia.org/wiki/25-pair_color_code

   If looking at the cable's core and the switch is in that direction, the groups are counted counter-clockwise. If the cable is the field side, the count is clockwise. There are indicators on the mylar ribbons to know where to begin for each layer and a diagram for the different cable sizes should be readily available for reference. [5] [6]

6. IEC metric screw sized connectors - Wikipedia

   en.wikipedia.org/wiki/IEC_metric_screw_sized...

   M12 A-coded 5-pin connector: For each connector size, the A-coding is the inspecific pinout variant and the only variant defined in varying numbers of pins. Ethernet cable with an M12 X-coded connector in one end and a modular connector in the other.

7. DMX512 - Wikipedia

   en.wikipedia.org/wiki/DMX512

   3: Connector: 1: Pinout; Pin 1: Signal Common: Pin 2: data-Pin 3: data+: DMX512 over XLR3 is prohibited by section 7 of ANSI E1.11 - 2008. Despite this, 3-pin XLR has become a de facto standard within the lighting industry. See the XLR-3 pinout section for more details.

8. Ethernet crossover cable - Wikipedia

   en.wikipedia.org/wiki/Ethernet_crossover_cable

   This wiring scheme constitutes a crossover cable. A crossover cable may also be used to connect two hubs or two switches on their upstream ports. Because the only difference between the T568A and T568B pin and pair assignments are that pairs 2 and 3 are swapped, a crossover cable may be envisioned as a cable with one modular connector following ...

9. NEMA connector - Wikipedia

   en.wikipedia.org/wiki/NEMA_connector

   Per UL Standard ANSI/UL 498, a receptacle (any color) with an orange triangle, is an isolated ground (IG) device, where the grounding pin of the receptacle is connected to ground independently of the frame of the receptacle and wiring outlet box. This is also a requirement of the National Electrical Code (NFPA 70), Article 406.
