AT&T DEFINITY Remote Port Security Device - Manual (Page 22)

Location of Administration Terminal or Printer
For the purposes of installation, it is simplest if the RPSD Lock or Key administration terminal or
printer is co-located with the RPSD Lock or Key. However, this is not always possible. In the
event that the terminal or printer must be located at some distance from the RPSD Lock or Key
(in another room, on another floor, etc.), the limitations of the EIA-RS232 interface must be
considered.
To overcome such restrictions, the baud rate of the administration terminal or other equipment
connected to the Aux. Port should be adjusted as follows:
■
■
■
Cables of 0-50 feet - a maximum 9600 baud
Cables of 50-100 feet - a maximum 4800 baud
Cables of 100-2000 feet - a maximum 2400 baud
Set the link speed by using the Set Communications Parameters command from the Menu of
Commands. See Chapter 3, RPSD System Administration for details on using this command
with the RPSD Lock or Chapter 4, RPSD Key Use for details on using this command with the
RPSD Key.
