Section 2, Engineering Guidelines ATLAS 550 System Manual

CONTROL IN Port

The CONTROL IN port (RJ-45) connects to a computer or modem or to another ATLAS 550 unit. The CONTROL port input provides the following functions:

•Accepts EIA-232 input from a PC or a modem (for controlling the ATLAS 550)

•Operates at 2400, 9600, 19200, or 38400 bps

•Acts as input for either VT100 terminal or PC (with terminal emulation software) control

•Acts as an interface for flash memory software downloads and configuration transfers using XMODEM

The CONTROL IN connection follows, and Table 4 shows the pinout.

Connector type RJ-48C

		Table 4. CONTROL IN 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

CONTROL OUT Port

The CONTROL OUT port (RJ-48C) connects to other ADTRAN products’ CHAIN IN connectors. The CONTROL port output provides the following:

•EIA-232 output to chain control to other ADTRAN equipment, such as a TSU 120 or another ATLAS

•2400, 9600, 19200, or 38400 bps operation

•Automatic setup; no user input required

The CONTROL OUT connection follows, and Table 5 shows the pinout.
