Manual EKS Electronic-Key Adapter serial 1 General notes 1.1 Use of the manual This manual describes the technical features and the function of the EKS Electronic-Key adapter EKS-A-ISX-G01-ST09/03 with serial interface (order no. 084 750). The complete evaluation and interface electronics are integrated in this unit. 1.
Manual EKS Electronic-Key Adapter serial 1.7 Explanation of symbols The following symbols are used in this manual to identify important instructions and useful information: Information! Important information is provided to the user here. Warning! Risk of damage to material or machine. Danger! Risk to life and limb. 1.
Manual EKS Electronic-Key Adapter serial 2 Safety precautions The Electronic-Key adapter must only be employed and used in accordance with this manual. The Electronic-Key adapter is typically operated as part of a higher-level overall system, e. g. a machine installation. When designing machines and using the Electronic-Key adapter, the national and international safety and accident prevention regulations specific to the application must be observed, e.g.: EN 60204, Safety of machinery.
Manual EKS Electronic-Key Adapter serial 3 Function 3.1 Functional description The EKS is used for access control and monitoring on control systems (PC/PLC) or parts of control systems for machine installations. Instead of passwords, coded Electronic-Keys are assigned. In this way unauthorized access to control and display systems is prevented to the greatest possible extent. The EKS uses a non-contact, inductive read/write identification system.

Manual EKS Electronic-Key Adapter serial 4.4 DIP switch settings Using the DIP switches S1 to S8, various parameters can be set. Write protection can be enabled using DIP switch S1. In this way the writing of data to the Electronic-Key read/write is prevented. The settings are only applied when the power supply is switched on.
Manual EKS Electronic-Key Adapter serial 5 Mounting Mounting must be performed only by authorized personnel. To achieve the degree of protection IP 67, it is necessary to install the Electronic-Key adapter in a clean, flat metal plate at least 2 mm thick and to tighten the screws to a tightening torque of at least 0.25 Nm. The Electronic-Key adapter is intended for mounting in control panels with a cut-out measuring 33 mm x 68 mm according to DIN 43700 (see page 8 chapter 4.
Manual EKS Electronic-Key Adapter serial 6 Electrical connection Electrical connection may only be performed by authorized personnel trained in EMC and with the device and wiring isolated. For use and operation as per the be used. requirements, a power supply for use in class 2 circuits must The Electronic-Key adapter is only allowed to be connected if it is electrically isolated. Otherwise the Electronic-Key adapter may be damaged. If connected incorrectly, the Electronic-Key adapter may be damaged.

Manual EKS Electronic-Key Adapter serial 7 Setup Setup is to be performed in the following sequence: 1. Set the DIP switches on the Electronic-Key adapter (see page 10 chapter 4.4). 2. Check mounting and electrical connection are correct (see page 11 chapter 5 Mounting and page 12 chapter 6 Electrical connection). 3. After the power supply is switched on, the LED on the front of the Electronic-Key adapter illuminates green. This indicates that the power supply is present. 4.
Manual EKS Electronic-Key Adapter serial 8 Operating the Electronic-Key-System using the serial interface 8.1 Special features of the serial interface If there is an Electronic-Key within the operating distance of the Electronic-Key adapter, the LED on the front changes from green to yellow. At the same time the OUT handshake signal (for use as CTS signal) changes from inactive (0) to active (1).
Manual EKS Electronic-Key Adapter serial 8.3.1 Special features of the 3964R data transfer protocol [1] The 3964R data transfer protocol is a comparatively reliable protocol for the electronic exchange of data between PC/control system and a peripheral connected, because the data transfer is performed using a standardized protocol. On control systems with an integrated 3964R driver (see e. g.
Manual EKS Electronic-Key Adapter serial The peripheral monitors the amount of time between the incoming characters. The gap between two characters must not be more than the character delay time (CDT, typically: 100 ms). All 10hex values contained in the message core must be sent twice so that the recipient recognizes that here information is being transferred and not the control character DLE (DLE duplication).
Manual EKS Electronic-Key Adapter serial 8.4 Commands for writing and reading an Electronic-Key read/write Write and read processes are always initiated by the PC/PLC (control system) using a "command message". The Electronic-Key-System then sends a reply message to the control system. PC/PLC (control system) Electronic-Key-System Command message −→ Reply message ← On Electronic-Keys read/write with 116 bytes, the memory is organized in 4-byte blocks.
