DELTAQUEST OEM 2-DOOR ACCESS CONTROLLER PCB
DQ-S2-PX
'Versatility to support access control and membership applications'
The DQ-S2-PX DeltaQuest universal OEM 2-door access controller PCB can be fitted into a third-party housing to provide I/O support for PC-based access control or membership software that needs to manage access points. Up to 32 access points that use ID devices such as card readers and keypads can be supported via a single USB port or a TCP/IP network connection.
PRODUCT FEATURES & BENEFITS
Each reader control module can manage up to two ID devices and operate their associated barriers or turnstiles via robust output relays.
Each DeltaQuest module collects ID data from the attached card readers or keypads and sends it together with the identity of the reader/keypad to the third-party software via the master module. If the software identifies that the ID data is valid, it can permit access to the user through the barrier or turnstile by sending a simple command to the corresponding DeltaQuest module via the master.
The DeltaQuest is ideal for use in the leisure industry when combined with third-party membership software.
The DeltaQuest is compatible with all Nortech’s reader technologies and can support many third-party readers and keypads.
Benefits
- Supports most reader technologies and output formats
- Up to 32 access points can be managed via a single USB port or TCP/IP network connection on the PC
- Supports PINs of up to 15 digits from a connected keypad
- Simplifies software development by using a simple command structure
- Simple, cost-effective installation with no local settings such as DIP switches or jumpers required
- Fully configurable via user-friendly software
- Compatible with several third-party database/membershipmanagement systems
- Each reader interface supports Free Exit and an auxiliary output to control card capture, DVR, etc.

Seamless OEM Integration for Custom Access Control Solutions
The DeltaQuest PCB module is designed for system integrators and OEM partners who need to embed robust access control functionality into their own enclosures or third-party housings.
This is particularly valuable in leisure facilities, fitness centres, and membership-based venues where existing IT infrastructure or bespoke cabinet designs must be maintained. The compact 125.5mm × 125.5mm form factor allows placement in control panels, kiosks, or custom-built reception desks without compromising functionality.
Installation teams working with golf clubs, social clubs, and corporate wellness centres benefit from the flexibility to integrate the controller directly into turnstile pedestals or barrier housings.
The module supports both USB and TCP/IP connectivity, enabling deployment in facilities where network infrastructure varies across entry points. When combined with membership management software such as Gladstone or Legend, the DeltaQuest PCB transforms standard entry barriers into intelligent member verification stations.

Scalable
Connect up to 32 access points through a single USB or TCP/IP connection.
Multi-Format
Compatible with Wiegand, C&D, and RS232 reader output formats.
Compact
Board-only design at 125.5mm² fits into any OEM housing.
Developer-Friendly
Simple command structure accelerates software integration.
The DeltaQuest PCB supports most reader technologies including Wiegand (26/34-bit), Clock & Data, and RS232 formats. It provides 12V DC or 5V DC power to connected readers (200mA max at 12V).
A single USB port or TCP/IP network connection can manage up to 32 access points using DeltaQuest modules in a master/slave RS485 configuration with cable runs up to 1200m.
The DQ-S2-PX requires an external 12V DC power supply capable of delivering 1A maximum. The board itself draws approximately 200mA at 12V DC during typical operation.
Yes, it is compatible with leading membership management platforms including Gladstone Health & Leisure, EZ Runner, Legend, and SDA Software, plus any system that can issue simple serial commands.
Each reader interface provides a voltage-free changeover relay rated at 2A @ 30V DC for barrier control, plus an auxiliary open-collector output for DVR triggering or card capture devices.
