dBDR - dB Drag Racing Systems for Car Audio Competitions

Description

dB DR components are the interface between pcRTA and the light trees used in dB Drag Racing events to display the SPL level of each vehicle. The complete system consists of the DBDR-224 I/O Interface Card, the DBDR-224 Power Module, and the connection cable.

This kit is ideal for a do-it-yourself project, where you wish to construct your own custom light trees and/or tower.

Note: This system DOES NOT include any lights, towers or AC wiring. We do not manufacture light towers.

dBDR-224 Power Module
The power module provides 2 sets of 24 solid state relays (48 SSRs total) with a capacity of 2A/240VAC per circuit. Each set is wired as (3) groups of 8 circuits, with one common power input per group. The terminal blocks accept 12-18 ga stripped wire. The control input signals are supplied through a 50 pin SCSI-II connector, PCB mounted. The module is 12.5 inches x 5.0 inches, heigth less than 2.0 inches. Eight mouting holes are provided.

dBDR-224 I/O Interface Card

dBDR-224 Interface Cable

The I/O interface is an 8-bit ISA bus card which is mounted in a PC computer. The unit provides 6 bytes of registers configured as (2) sets of three each. I/O port base address is selectable as 0300h or 0310h.

Output drive can be True or Complement. Control power (GND or VCC) is also fed via two pins through the connector, along with the 48 output drive signals. All output signals are supplied through a 50 pin SCSI-II connector.

This is a 6 ft cable used to connect the I/O card to the power module. The format uses 50-Pin SCSI-II connectors.
