Figure 3.2 SEL-3031 Port Settings for MIRRORED BITS Connection
The SEL-3031 makes it very simple to set a MIRRORED BITS connection. Only the
PROTO setting is needed to set the M
IRRORED BITS port. The SEL-3031 without an
encryption card has fixed data rate of 19200 bps (8, N, 1) so no other setting changes
are needed.
On Port 1 on each radio install a 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 then the IED connection
needs to be an SEL-2812MR Fiber-Optic Transceiver.
