Communications
3.2
The SEL-3031 can handle as many as three connections of M
IRRORED
B
ITS
®
simultaneously over one radio link. For this example, there are three M
IRRORED
B
ITS
channels over the SEL-3031. This example shows you how to set the radio and set
different end devices to properly use the radio as a M
IRRORED
B
ITS
link.

Settings
For Figure 3.2 , we set Port 1 on both SEL-3031 devices as a M
IRRORED
B
ITS
connections.
On each radio, set the following settings on the Port 1 settings.

ITS
Connection
The SEL-3031 makes it very simple to set a M
IRRORED
B
ITS
connection. Set the
PROTO setting to MB8 to make it a M
IRRORED
B
ITS
port. The SEL-3031 without an
encryption card has data rate of 9600, 19200, or 38400 bps (8, N, 1). Setting the speed
to 38400 provides the lowest latency at the cost of disabling Port 2. Port 3 can still be
used for data at 9600 or 19200 bps speeds.
On Port 1 on each radio, install an SEL-C285 cable to the IED device. As an
alternative, the SEL-3031 can be ordered with a fiber-optic serial port that works with
SEL-2812 transceivers. If you use the fiber-optic port on the SEL-3031, the IED
connection needs to be an SEL-2812MR Fiber-Optic Transceiver.
