TUNING PROCEDURE TR4022 1.0 INTRODUCTION This document describes the procedures required to properly tune a Strata System with the TR4022 board. Many of the adjustments for the Strata are pre-tuned during the manufacturing test process therefore adjustments required in the field have been minimized. Adjustments such as center frequency and sweep are preset for 8.2 Mhz operation. If the system is required to detect a different frequency tag the sweep range will need to be readjusted by the installer.
TUNING PROCEDURE TR4022 The switching between antenna loops minimizes the size of detection holes at the null points of the RF field. 3.0 SWITCH SETTINGS Table 1 explains each of the jumpers on the TR4022 board and 4.0 explains the switches on the TR4022 board that must be configured before the system will operate. The illustrations on the next pages shows the position of the jumpers, switches, and potentiometers on the TR4022 board used during configuration.

TUNING PROCEDURE TR4022 Switch 6 – Master/Slave configuration ON OFF Switch 6-1 Master (generates and Slave (system must receive distributes RF and Sync) Sync signal) The Master/Slave switch controls how the system will handle the sync and rf signals in and out. A system MUST be in slave mode to use these input signals. In Master mode these signals must be absent (refer to ‘Sync and RF indicators’ section).
TUNING PROCEDURE TR4022 4.0 LED DEFINITIONS System Status Indicators DS1 – Inhibit Indicator This LED indicates that a condition exists that would prevent normal detection of a tag, typically excessive environmental noise. (At the end of an alarm cycle the inhibit LED will light momentarily) DS2 – Alarm This LED indicates the system is alarming (useful for when the sounder and lights are disconnected). DS3 - Heartbeat This LED indicates the system is operating normally.
TUNING PROCEDURE TR4022 The system will not operate in any of the above ‘ERROR’ conditions. If an error condition is indicated the transmitter will be shut down and the system will not ‘pass through’ the sync pulse. 5.0 POTENTIOMETER ADJUSTMENT The table below provides all of the adjustment pots on the TR4022 board along with their function and how to adjust each pot. The factory should set all of these pots and field adjustment should not be necessary.

TUNING PROCEDURE TR4022 Screen 7 Screen 7 Alarm Counter Display (above shows 29) 8.0 TUNING 8.1 Master / Slave Setup The first step in the process for tuning a Strata pedestal with the TR4022 board is to configure SW 6-1 according to how the pedestal is used in conjunction with other pedestals. Configure either as a Master (ON) , or Slave (OFF). See Switch 6 – Master/Slave configuration 8.
TUNING PROCEDURE TR4022 Apply 24 VDC power and check that DS11 is illuminated. DS3 should also be flashing intermittently. The transmitter output is preset at the factory and should not require adjustment. Adjust the baseband gain potentiometer R89 for a noise level of less than 1.5V at Screen 1. This can be viewed by attaching an oscilloscope to the DAC test point TP16 and selecting Screen 1 by depressing SW2. Scope setting: 1V/DIV; 200uS/DIV.
