SDIO Module Connectors and Indicators

Configuring a System with an sDIO and a RIO

When a system contains an sDIO module and a RIO, you must use the DC_SETUP.V2 program to select a block number for the RIO. This is described in the documentation supplied with the RIO. Typically, you would use default block 16 for the sDIO, and select block 17 for the RIO.

Once the RIO block number is selected, then you assign I/O signal numbers for the RIO using the CONFIG_C.V2 utility. This is the same process as described earlier for the sDIO.

1.Status LEDs.

Two LEDs indicate link status of the IEEE 1394 connection and system status.

LINK: Green LED = communication with another device over IEEE 1394 connection OK.

OK/SF: Red LED = output driver fault detected due to excessive temperature or current (output is automatically shut down), solid green LED = communication with controller OK, blinking green = not configured in software.

2.IEEE 1394 ports: Connects to one of the SmartServo ports on SmartController or IEEE 1394 ports on additional sDIO units.

3.X1 Output: 44-pin female D-sub connector, for digital output signals 0033-0048.

4.X2 Output: 44-pin female D-sub connector, for digital output signals 0049-0064.

5.X3 Input: 26-pin female D-sub connector, for digital input signals 1033-1048.

6.X4 Input: 26-pin female D-sub connector, for digital input signals 1049-1064.

NOTE: For installations that use two or more sDIO modules, the above signal numbers apply to the signals for the first sDIO. See the V+ documentation for information on configuring two or more sDIO modules.

7.Two 24VDC connectors: Connect power from the XDC2 connector on the SmartController to the XDC1 connector on the sDIO (see the “Connecting Power” section on page 30 for power specifications).

103 RS-422/485, XSYS, XUSR, RS-232/TERM specifications

Nortech Systems offers a comprehensive suite of serial communication solutions, including RS-232/TERM, XUSR, XSYS, and RS-422/485 interfaces. These products are designed to facilitate reliable and high-speed data transmission in various industrial applications, making them essential for connecting devices in automation, telecommunications, and data acquisition systems.

The RS-232/TERM interface is a widely adopted standard for serial communication, known for its simplicity and robustness. It supports point-to-point communication over relatively short distances, typically up to 50 feet. Key features include a maximum baud rate of up to 115.2 kbps, error-checking capabilities, and a straightforward connection process, making it ideal for connecting peripheral devices like printers, modems, and barcode scanners.

Building on the RS-232 standard, the XUSR and XSYS devices offer enhanced functionalities and flexibility. XUSR, for instance, supports not just traditional RS-232 connections, but also protocol conversion for various serial interfaces, facilitating seamless integration of legacy systems with modern networking technologies. It is particularly useful in environments where multiple protocols need to be managed simultaneously.

XSYS is designed for more complex applications and supports advanced communication features such as multi-drop configurations, enabling it to connect multiple devices on a single bus. This makes it suitable for extensive industrial networks where space and wiring complexity need to be minimized. Synchronous and asynchronous data transfer modes ensure that the XSYS is adaptable for both real-time data collection and standard command-response applications.

On the other hand, RS-422/485 interfaces excel in long-distance communication, allowing for data transmission over distances up to 4,000 feet. They are designed for multi-point connections, supporting up to 32 devices on a single bus through differential signaling, which enhances noise immunity. These characteristics make RS-422/485 particularly well-suited for environments with electromagnetic interference, such as factories or subways.

Nortech Systems’ serial communication solutions emphasize reliability, ease of use, and versatility. With their commitment to high performance and user satisfaction, these interfaces provide critical connectivity in today’s increasingly automated and interconnected world. Whether in data centers, manufacturing setups, or remote sensor networks, Nortech's offerings stand out for their reliability, efficiency, and adaptability, ensuring effective data communication across diverse applications.
