Note:

In all cases, do not work or position equipment over an active traffic lane. Working

over active lanes presents a hazard to the installer and to travelers using the highway.

Follow local authorized procedures when installing the SAS-1 unit and any associated

components or subsystems.

SAS Relay Interface Configuration and Connection Many traffic monitoring sites in place (or planned) and traffic counters use the traditional controller interface approach of vehicle presence relay signals. The SAS Relay Interface is used with the SmarTek Acoustic Sensor (SAS-1) to provide physical vehicle presence relay signals Shelf Mount Type 170 Card to a cabinet controller or traffic counter . The SAS Relay Interface (SAS-RI) is available in two form factors (Figure 1).

Connecting and Routing Relay Signals For The SAS-RI Type 170 Card The type 170 card version is comprised of a Main D1 D2 SAS-RI Main Card and up to two SAS-RI Daughter Cards (D1 and D2) as shown in Ribbon Distributes Figure 3. Each SAS-RI Main and Daughter 10 Relay Signals Card has a ribbon cable header for relay distribution and a Relay Routing Matrix.

a card edge contact (F, W, S, Y). From Figure 4 it can be seen that the SAS-RI Main card routes relay signals 1A, 1B, 2A, and 2B to four card edge contacts. The SAS-RI Daughter Card 1 routes relays signals 3A, 3B, 4A, and 4B to four card edge contacts. And finally, the SAS-RI Daughter Card 2 routes relay signal 5A and 5B to two card edge contacts. For Type 170 card files, contacts S and Y are routed to contacts F and W respectively in the adjacent lower numbered slot (i.e.

should light based on detections by the SAS-1. To setup SAS-1 or to repeat the SAS-1 setup using the SAS Monitor and Setup software, connect the supplied serial cable from the PC running SAS Monitor and Setup directly to the SAS-CT (in place of the cable connecting the SAS-RI). After setup of the SAS-1 is complete, replace the cable from the SAS-RI (RJA) to the SAS-CT. Press the SAS-RI Reset switch on the SAS-RI front panel. The Activity LED should begin to blink after approximately 6 seconds.

on the second SAS-RI to the RJA jack on the third SAS-RI. This pattern continues for up to 6 SAS-RI cards. Note: Each SAS-RI used as slaves (SAS0002 thru SAS0006) in Figure 6 must be factory modified for receive only capability. They are not interchangable with the SAS-RI used as the Master (corresponding to SAS0001).
