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 1 gives the CRAFT port pinout.

Connector type	RJ-48C
		Table 1. CRAFT Port Pinout
PIN	NAME	DESCRIPTION
1	GND	Ground - connected to unit chassis
2	RTS	Request to send - flow control
3	RXDATA	Data received by the ATLAS 550
4	DTR	Data terminal ready
5	TXDATA	Data transmitted by the ATLAS 550
6	CD	Carrier detect
7	UNUSED	—
8	CTS	Clear to send - flow control

Front Panel LEDs

With the ATLAS 550 powered-up, the front panel LEDs provide visual information about the status of the ATLAS 550 and any option modules that may be installed. Table 2 provides a brief description of the front panel features, and Table 3 on page 27 provides detailed information about the LEDs.

	Table 2. ATLAS 550 Front Panel Description
Feature		Description
Controller Status LEDs		Displays the general status of the entire ATLAS 550. (See Table 3 on page 27.)
Power		Indicates the unit is on or off.
System		Indicates the status of the system.
Ethernet		Indicates the status of the Ethernet port.
Remote		Indicates whether a user is logged into the unit.
Network Module LEDs		Displays the status of the network interface. (See Table 3 on page 27.) All
		LEDs are off if no network module is installed.
OK		Indicates that the network interface is operating correctly.
Test		Indicates that the network interface is in test mode.
Error		Blinks to indicate the occurrence of error events.
Alarm		Indicates an alarm condition on the network interface.
