| Serial Ports Four general-purpose serial ports are provided to enable network clients to monitor and control remote serial devices over an Ethernet. Each port is independently configurable for RS-232, RS-422 or RS-485 operation. Standard baud rates up to 115.2 Kbps are supported. These ports are useful for communicating with bar code scanners, motor controllers and other remotely located serial devices. Interlocks Integral support is provided for up to five independent interlock or emergency stop circuits. An innovative routing system allows these circuits to be directly connected to the 2601, which in turn distributes the interlock signals directly to its I/O modules. This makes it possible to implement fail-safe interlock operation without the extra costs (e.g., complex wiring, external terminal blocks) that are typically associated with interlock circuits. In addition to routing the interlock signals, the 2601 also monitors the interlock signals and reports their states to Ethernet clients on demand. Low-cost cables Each I/O module connects to the 2601 with a standard Category-5 patch cable. This cable delivers power to the I/O module and it carries the optically-isolated communications between the 2601 and I/O module. Some I/O module types, such as the 2652 Solid State Relay module, also require a daisy-chain power cable (Sensoray part number 2600C1) for interlock circuit connections.

Field Wiring
I/O modules employ two-piece mating connectors for quick connections to all field wiring. External termination boards are not required, as all field wiring connects directly to the I/O modules. This helps to minimize intermediate termination systems and wiring, thereby reducing both material and assembly costs. Mechanical
Series 2600 modules are supplied as open-frame circuit boards mounted in robust, uniform 100-mm wide DIN rail mountable frames. These are designed to quickly attach to and detach from standard 35-mm-wide DIN rails. Unlike panel mounted products, DIN rails do not require precise mounting hole positions and time-consuming assembly, thus lowering overall installation costs. Open-frame design has been applied to all modules in the 2600 family. Field wiring connectors are conveniently located at module edges for easy cable routing into adjacent wiring ducts. This eliminates the expensive module enclosures that are often required by competing products. Power Daisy-Chain
Most I/O modules require only the 24VDC operating power that is supplied from the Communication Module through the category-5 patch cable. Exceptions to this are the relay module (model 2650) and digital I/O module (model 2610). These modules obtain their I/O circuit power from a separate power daisy-chain connector. This enables each I/O point to be powered from any of six different power sources. In the case of digital I/O circuits, for example, some channels can operate from 5V power while others operate from 12V power (requires external 5 and 12 VDC power supplies). Interlocks
Daisy-chain power sources may be constant voltages, or they may be switched by interlock and/or emergency stop circuits. When switched power is used, each relay and digital output can be configured to unconditionally deactivate when the switched source is powered down (i.e., when a safety interlock or emergency stop contact opens). This guarantees fail-safe deactivation when safety conditions require it. Multiple Ethernet Clients
The 2600 system is simultaneously accessible from multiple LAN hosts. For example, a laptop can be connected to the LAN to monitor the I/O system and obtain diagnostic information without interrupting the control computer. Or two or more control computers can be connected, each controlling its own private I/O resources. Software & Manuals A software developer’s kit (SDK) for the 2600 series is available below. This kit includes hardware and software manuals, libraries for Windows 98/NT/2000/XP and Linux, and sample application programs. A serial port redirector is also included with the SDK. This software enables an unmodified application program to communicate with a remote 2601 serial port as if it were a standard serial port on the host computer. This is useful for situations in which a legacy program is designed to communicate with a device through a local serial port, but the device is physically connected to one of the serial ports on a 2601.
