EIA STANDARDS
to meet both the EIA protocol standards, and the
needs of the industry.
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.
±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.
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
