EIA Standard Definitions EIA STANDARDS The Electronic Industry Association (EIA) de- veloped several standards of data transmission which are revised and updated in order to meet the requirements of the industry. In data pro- cessing, there are two basic means of communi- cating between systems and components. The RS-232 standard was first introduced in 1962 and, since that time, has become an industry standard. The RS-232 is a relatively slow data exchange protocol, with a maximum baud rate of only 20kbaud, which can be transmitted over a maxi- mum copper wire cable length of 50 feet. The SP200 through SP213 Series of data communi- cations interface products have been designed to meet both the EIA protocol standards, and the needs of the industry. ±10kV ESD PROTECTION The SP200 Series is equipped with Sipex-pro- prietary ESD protection circuitry on all RS-232 inputs and outputs. The SP200 Series has been characterized using MIL-STD-883C Method 3015.7 Human Body Model. Each device in the family can withstand up to ±10kV of static discharge on all RS-232 inputs and outputs. All other pins of each device will maintain ≥ ±2kV of ESD protection. |
