68 EOT Telemetry DevicesTo calibrate the EOT:1. Charge the brake pipe and connect the EOT.2. Compare the pressure displayed at the EOT to the pressuredisplayed on the LCU.3. Make sure the two readings are within ± 3 psi of each other.4. Detach the EOT from the brake pipe and connect an accurate(calibrated) gauge.5. Compare the pressure indicated on the gauge to the brake pipepressure readout on the LCU.6. Make sure the pressure indicated on the gauge is within ± 3 psiof the LCU readout.NOTE: Do not use an EOT that displays a pressure notwithin ± 3 psi of the LCU readout or the accurate (calibrated)gauge.7. The person at the EOT uses a pen to enter the following informationon the Calibration Date Tag:• Name• Date• Location of test8. Attach the Calibration Date Tag to the EOT.68.6 Overview Of Glenayre Digitair End-Of-Train Telemetry DeviceThe Glenayre Digitair is a radio end-of-train telemetry system thatconsists of:• End-of-train (EOT) unit mounted on the trailing coupler of thelast car• Locomotive cab unit (LCU) mounted in the locomotiveJune 1, 1996 ARRC Air Brakes and Train Handling Manual 68-15
