If you orient your Pi such that you are looking at the top with the GPIO on the right and HDMI port(s) on the left, your orientation will match Pinout. Pin 1 is the only pin with a square solder pad, which may only be visible from the underside of your Pi. Pinout depicts pin 1 in the top left corner.

#PRI LOOPBACK CABLE PINOUT PATCH#
WiringPi - for Gordon Henderson's Wiring Pi library. If a straight through is going to be used, you can simply use a normal Cat5 patch cable as the pinouts on both sides of the wire will be identical.RS232 DB9 and DB25 Loopback Pinout Loopback is a. These are the small numbers next to the header, e.g. Since there is no DCE to raise CTS, the outgoing RTS signal is looped in the NULL modem cable to the. Physical - or "Board" correspond to the pin's physical location on the header.You'll use these with RPi.GPIO and GPIO Zero. GPIO - General Purpose Input/Output, aka "BCM" or "Broadcom".

Figure 3 applies to most BB RS-485 Converters or Serial Cards that can be set for 2-wire or 4-wire operation and for some 2-wire Converters that use the same circuit. A wiring diagram is a streamlined traditional pictorial representation of an electric circuit. If you manufacture boards, we'd love to add yours too.

If you see that the router sends no errors (as 99.99% of the cases), then the circuit is faulty. Ask them to bring a circuit analyzer to be inserted between router and circuit termination. JTAG Pinout Tool Q: How many contacts on the card terminal can be analyzed A: The possibility of analyzing 18 contacts on your phone or modem card. All failing, put the burden of proof on the telco.

upgrade IOS to latest 12.4 or 12.4T (just as a caution). Ethernet is twisted differently and should not be used, espcially for long runs. Make sure you do not use ethernet patch cables, but twisted pair with the correct pinout. It seems strange to me that the clock is show as "derived from backplanes" in show controller. In particular, it seems like the switch is either loosing or receiving errors from the router, as it continuously tries to reinitialize L2. It is evident that the circuit is so severely errored that no reliable link can be established, hence L2 flaps continuously.
