Pay close attention to the polarity of the +15 Vdc.Revers- ing the connections can cause damage to the TLS RF. 4. S2 DIP switch 7. Cable from battery pack 5. Red LED—Flashes only when radio is powered on in Diagnostic Mode. 4. Using a#15 torx driver, open the covers of the TLS RF, Repeater and Receiver. Make a temporary ac power cord with a grounded plug on one end. Connect the ac power cord to the TLS RF's input power terminals and ground terminal (refer to Figure 6 and Figure 7). Connect a necessary length of RS-485 cable from the TLS RF's RS-485 terminals to the Receiver's RS-485 terminals (refer to Figure 20). Connect a necessary length of 2-conductor cable from the Receiver's Repeater terminals to the Repeater's Repeater terminals (refer to Figure 21). 5. The steps below are to verify the communication between the TLS RF Unit and the Receiver. a. Plug the TLS RF's ac power cord into a 120/240 Vac outlet. Confirm the Green /Red LEDs (refer to item 2 in Figure 12), are flashing rapidly.This is an indication there is RS-485 network activity between the TLS RF and the Receiver. b. If it is, continue to Step 6. c. If it is not, check PWR LED (refer to item 3 in Figure 12), if not lit; check power wiring. If the wiring is correct, measure the voltage across the twisted pair power wires, it should read +15Vdc. If it is not, the TLS RF is bad. 10-12 GARB Approved IOM 10-Veeder Root TLS RF Wireless Systems(W2)-Executive Order VR-202
