CRAFT PORT
Use the CRAFT port to configure the system via an EIA-232 connection. The
CRAFT port provides the same functions and operations as the Control In
port located on the rear panel of the ATLAS 550. The connector type is
shown below, and Table 4-1 gives the CRAFT port pinout (see also CRAFT
Port on page 4-3 in Table 4-2).
FRONT PANEL LEDS
With the ATLAS 550 powered-up, the front panel LEDs provide visual in-
formation about the status of the ATLAS 550 and any option modules that
may be installed. Table 4-2 on page 4-3 provides a brief description of the
front panel features, and Table 4-3 on page 4-4 provides detailed informa-
tion about the LEDs.
