This section describes the characteristics and operation of all connectors on the LS424.

The LS424 has an RJ45 connector for 100BASE-TX networking. The maximum length for Cat 5E cable is 100 meters; the allowed length can be higher or lower depending on the quality of the cable.

802.1x is supported on the ethernet port, but not on USB-connected ethernet devices.

The power connector for the LS424 is a USB Micro-B port rated for 5V@2A. The connector is used for power input only—it does not transfer data.

The LS424 has a USB 2.0 Type-C port, which is capable of transfer speeds up to 480 Mbit/s. 

The USB connector can supply up to 0.5A of power for peripherals.  The maximum length for a USB cable is 5 meters.

The USB Type-C port will output analog audio if the CC1 or CC2 signal is shorted to ground via a 1K resistor. Analog output can also be enabled in system software. The Dp signal outputs right audio, and the Dn signal outpts left audio.

The following table illustrates the pinout of the USB 2.0 Type-C host port:

USB 2.0 Type-C Pinout

The serial port supports TTL signaling and is located on the the A2/A3 and B2/B3 pins. It enumerates as port 0.

The serial port is disabled by default. It can be enabled/disabled by writing to the player registry using BrightScript (via 

 output is an HDMI 1.4a connector used to send digital video and audio to HDMI-enabled sink devices. It is capable of outputting a maximum video resolution of 1920x1080x60p.

In-Vitro Fertilization. In relation to embryo transfers, IVF occurs when oocytes (eggs) are collected via OPU (ovum pick up), and then in a lab, semen is added to create embryos.

Vet Code 6 = ABT? Often if a dairy sees a pregnant animal showing signs of heat they may breed her. When this breeding is entered in DairyComp the animal remains pregnant, but this flag is set so that the veterinarian can determine if she is still pregnant to the original breeding or if she has aborted and is now just another "bred status" cow.

Dairy cattle typically have their hooves inspected and, if necessary, trimmed every 4–6 months. A strategic hoof-trimming program might evaluate hooves before first calving, between 60 and 150 days in milk, and before dry-off.

Mastitis is the persistent, inflammatory reaction of the udder tissue due to physical trauma or infection. Symptoms of mastitis include udder swelling, heat, hardness, redness, or pain. The milk may have a watery appearance, flakes, clots, or pus.

Metritis is inflammation of the wall of the uterus, and usually occurs within days of calving. Symptoms of metritis are an enlarged uterus and a foul-smelling uterine discharge.

Pneumonia is lung inflammation caused by a bacterial or viral infection. Early symptoms may include fever, depression, reduced appetite, nasal and eye discharge, salivation, shallow breathing, and soft coughing.

Pneumonia

Lameness includes any abnormality which causes an animal to change the way it walks, and can be caused by a range of foot and leg conditions, including hoof ailments, hock damage, bruising, sores, or cuts.

Lame

Diarrhea in young animals. Scours causes dehydration in calves and is the leading cause of death in calves under one month of age.

Retained placenta is the failure to expel fetal membranes within 24 hours after parturition. The primary symptom of a retained placental is degenerating, discolored, and ultimately fetid membranes hanging from the vulva.

Retained Placenta

Ketosis is a common ailment that usually occurs in early lactation, when the energy demands of milk production are very high and the cow metabolizes fat stores for energy. Symptoms of ketosis may include reduced milk yield, weight loss, reduced appetite, acetone smell of breath and/or milk, and fever.

Ketosis

Milk fever is a disease characterized by reduced blood calcium levels. It occurs in early lactation, when demand for calcium for colostrum and milk production exceeds the cow's ability to mobilize calcium. "Fever" is a misnomer, as body temperature during the disease is generally not elevated. Milk fever symptoms include tremor in the muscles of the head and limbs until falling to a "sitting" position. Once down, cows may have a dry muzzle, staring eyes, cold legs and ears, constipation, and drowsiness.

Milk Fever

Displaced abomasum in cattle occurs when the abomasum, also known as the true stomach, which typically resides on the floor of the abdomen, fills with gas and rises to the top of the abdomen, where it is said to be "displaced". Symptoms may include reduced appetite, lower milk yield, reduced rumination, and a distended abdomen.

The term "Zone" represents different dairy locations. Platform Zones may be different physical dairy locations (for example, multiple locations across the state or country) or different user-defined locations within a single dairy site (for example, Pens 1-100 are Zone 1, Pens 101-200 are Zone 2, etc.).
