Product Features by Part Number
Sealevel uses a four-digit numbering system. The first digit defines the bus interface and the product category. The rest of the characters define the port count or functionality and vary by product family. The following list illustrates the major product categories. Follow the links to the category pages where you can generally identify your product by the photo shown:
- 1000 — Interface Converters
- 2000 — USB Serial
- 3000 — ISA Serial, PCMCIA Serial, PC/104 Serial, ISA Digital I/O and PC/104 Digital I/O
- 4000 — Ethernet Serial, ISA Digital I/O, ISA Parallel (obsolete), and ISA Synchronous Serial (obsolete)
- 5000 — PCI Synchronous Serial
- 7000 — PCI Express Serial, PCI & Low Profile PCI Serial, and Compact PCI Serial
- 8000 — PCI Express Digital I/O, PCI Digital I/O and USB Digital I/O
- 9000 — Custom designed products
SeaI/O data acquisition modules use a three-digit part number — digital I/O modules begins with a “4” or “5”; serial I/O modules start with a “6”; and accessory modules (e.g., isolated hubs) start with a “2”. The three digits are followed by a letter that defines the host interface connection that is detailed below:
- E — Ethernet (Modbus TCP) interface
- M — RS-485 (Modbus RTU) interface
- S — RS-232 (Modbus RTU) interface
- U — USB (Modbus RTU) interface
- W — Wireless 802.11b/g (Modbus TCP) interface
- N — Expansion modules (connect to other SeaI/O modules via pass-through connectors for local or remote I/O expansion)
