AT&T DEFINITY 555-230-223 - Manual (Page 39)

Installation
1. If you are installing a new terminal, unpack it according to the instructions
supplied with the terminal.
2. Place the terminal on a suitable table within 15 feet of the switch cabinet if
you have a 20-foot ED-1E434 Group 311 cable, or within 45 feet if you
have a 50-foot ED-1E434 Group 311 cable, and connect the keyboard.
3. Connect an ED-1E434 Group 311 cable between the DEFINITY LAN
Gateway system MFB and the terminal:
a. Attach one end of an ED-1E434 Group 311 cable (supplied with the
DEFINITY LAN Gateway system PEC) to the RS-232 connector
labeled PORT B on the MFB Y-cable.
b. If you connected a 116A to the PORT A and PORT B connectors
on the Y-cable (in Task 4), attach the ED-1E434 Group 311 cable
to the 116A (for a DTE connection). For a DCE connection, attach
another null modem to the 116A, and attach the ED-1E434 Group
311 cable to the other end of the null modem.
c. For a 715 BCT, attach the other end of the ED-1E434 Group 311
cable to the DCE connector on the back of the terminal. Then skip
to Step 4.
For a 513 or equivalent BCT, attach the other end to the female
connector on an H600-258 Group 1 null modem.
d. Connect the male connector on the null modem to an RS-232 serial
port connector on the back of the terminal.
4. Plug the terminal power cord into a wall outlet and power on the terminal.
5. Set the terminal options. See Appendix B, ‘‘Supported Terminals and
Modems/Option Settings,’’ for a complete list of option settings for
supported terminals.
NOTE:
When installing a serial printer on all but a 610 or 615 BCT, set the
options on the printer as described in the manual supplied with the
printer, then set the corresponding options on the terminal to match.
On the 610/615, set the terminal options first, then set the printer
options.
If the terminal is installed correctly (and the DEFINITY LAN Gateway
system is in either OAM or OS state), the screen displays the login
prompt.
If the terminal does not display the login prompt when the
DEFINITY LAN Gateway system is in one of the above states, try
pressing the
Return key a few times. If the login prompt still does not
appear, write down the state displayed on the LCD and then see the
troubleshooting procedure for terminal connections in Appendix D.
