Configuring a Single sDIO

4.Connect an IEEE 1394 cable from one of the SmartServo ports (1.1 or 1.2) on the SmartController to one of the IEEE 1394 ports on the sDIO. Continue to daisy-chain the IEEE 1394 power from each sDIO to the next.

WARNING: Remove power from the SmartController before plugging in or unplugging any IEEE-1394 cables to SmartServo IEEE-1394 connectors. Failure to remove power could result in unpredictable behavior by the system.

5.Connect the 24 VDC input power to the SmartController.

6.Connect a user-supplied ground wire to earth ground.

A.3 Configuring a Single sDIO

The SmartController is preconfigured to support one sDIO module. Its configuration is based upon an I/O block assignment method that uses 4 bytes per block and 8 signals per byte. Thus, each byte within a block represents an eight signal range of I/O.

Block numbers for general digital I/O can range from 16 to 31; the default is 16. Input blocks and output blocks are numbered independently so you can use the same number for both an input and an output block. You must be sure that the block number you specify is not used for the same type of block in any other sDIO module or RIO in your system.

Default sDIO I/O Configuration

A single sDIO module can be used with the default I/O signal configuration and no additional configuration is required. The following signal groups are predefined for use:

•Input signals 1033 to 1064

•Output signals 0033 to 0064

The default configuration consists of the settings shown in Table A-1.

Table A-1. Default I/O Configuration for sDIO

Input Signal	Block	Byte	Output Signal	Block	Byte
Numbers	Block	Byte	Numbers	Block	Byte
Numbers			Numbers


1033 to 1040	16	1	0033 to 0040	16	1

1041 to 1048	16	2	0041 to 0048	16	2

1049 to 1056	16	3	0049 to 0056	16	3

1057 to 1064	16	4	0057 to 0064	16	4

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.
