The larger storage capacitor injects a
higher voltage to the test point when SW2
is switched on. The lower current limiting
resistor increases the current charge onto
the test point.
The RS-232 is a relatively slow data exchange
protocol, with a maximum baud rate of only
20kbps, which can be transmitted over a
maximum copper wire cable length of 50 feet.
The SP207E through SP23E Series of data
communications interface products have
been designed to meet both the EIA protocol
standards, and the needs of the industry.
EIA STANDARDS
The Electronic Industry Association (EIA)
developed several standards of data
transmission which are revised and up-
dated in order to meet the requirements
of the industry. In data processing, there
are two basic means of communicating
between systems and components. The
RS--232 standard was first introduced in
962 and, since that time, has become an
industry standard.
