BROADCAST
The BROADCAST command (Access Level 1) allows you to communicate
from one master port to all IED ports simultaneously. When you issue the
BROADCAST command, the SEL-2032 will indicate the connected ports.
From then on, anything you enter will be sent to all connected ports.
Any messages from any of the connected IED ports will be sent to the single
master port, as long as they are framed with the <STX>/<ETX> characters. To
transfer binary messages, add an AAh byte after the <STX> character and
then a message length as the next byte. The SEL-2032 will use the message
length to determine the end of the message, instead of checking for an <ETX>
character.
Use the BROADCAST command with an R parameter to enter broadcast
communications in a receive-only mode. In this mode, master port messages
are used for connection termination only.
Exit broadcast mode by entering the transparent termination sequence defined
in the SEL-2032 master port settings. See Transparent Communications on
page 7.8 for additional discussion on termination sequences. You will need to
allow an extra second for TERTIME1 due to some additional BROADCAST
command delays. Note that the BROADCAST command is not supported for
virtual terminal master ports.
CAL
Use the CAL command (Access Level 2) to enter Access Level C. You need a
password unless the password disable jumper is installed (J17B in the
SEL-2032). Use the PAS SWORD command at Level C to change passwords.
Figure 8.6 shows successful access.
