The visual difference from the more-common 8P female is subtle. The RJ45S keyed 8P modular connector has only pins 5 and 4 wired for tip and ring (respectively) of a single telephone line, and a "programming" resistor connected to pins 7 and 8. [10] [11] [12]
GG45 is a variant of ARJ45 that allows for cables terminated with male 8P8C (AKA RJ45) connectors to be plugged into GG45 jacks. However, GG45 cables cannot plug into 8P8C jacks as a protrusion on the socket is designed to activate a switch on the jack for the alternative contact positions.
The connector provides power to the keyboard on the outer two contacts and receives data signals on the inner pair. The cable between the computer and the keyboard is a coiled cord with an appearance very similar to a telephone handset cable. [11] The connector on the Amiga 1000 uses crossover wiring, similar to a telephone handset.
For example, telephone cables in the UK typically have a BS 6312 (UK standard) plug at the wall end and a 6P4C or 6P2C modular connector at the telephone end: this latter may be wired as per the RJ11 standard (with pins 3 and 4), or it may be wired with pins 2 and 5, as a straight-through cable from the BT plug (which uses pins 2 and 5 for the ...
Perhaps the most comprehensive known and most discussed feature of ANSI/TIA-568 is the definition of the pin-to-pair assignments, or pinout, between the pins in a connector (a plug or a socket) and the wires in a cable. Pinouts are critical because cables do not function if the pinouts at their two ends aren't correctly matched.
The most common type uses Category 5 cables (four twisted pairs with 100 ohm impedance) between 8P8C (colloquially and incorrectly called RJ45) room sockets and a central patch panel. The A and B wires of an analogue phone line appear in a structured cabling system usually on the centre pins of the 8P8C connector (pins 4 and 5; the blue/white ...
shielded or unshielded Cat5, Cat5e, Cat6 or Cat6A cables using 8P8C (RJ-45) modular connectors with straight-through T568A or T568B wiring (modular cables wired to T568A at one end and T568B on the other are more commonly referred to as crossover cables) qualified optical fiber cables for use with modular fiber optic spectroscopy equipment
A keystone module for a CAT5 network cable A 3-port keystone wall plate. A keystone module is a standardized snap-in package for mounting a variety of low-voltage electrical jacks or optical connectors into a keystone wall plate, face plate, surface-mount box, or a patch panel.
