SEL-2020 Instruction Manual
Connect the IRIG-B terminal at the Y end to the relay’s AUX input port. Connect the single
connector end of the cable to Port 2 on the SEL-2020.
2. Connect a Modbus master device to an SEL-2020 Modbus port; this example uses Port 16.
3. Change the SEL-2020 access level to Access Level 2 on the SEL-2020 and issue the
command SET P 16 to configure Port 16. The SEL-2020 will prompt for the type of device
connected to the port. Enter M for Master, enter M a second time for Modbus protocol.
Select the default floating-point map and set the start ID to 0. Assign an address to Port 2
and enter OFF for other port addresses. See the following example:

4. Issue the command SET P 2 to configure Port 2. The SEL-2020 will prompt for the type of
device connected to the port. Enter S for SEL IED, enter Y to auto-configure the port, and
press <ENTER> to confirm the configuration prompts. The SEL-2020 will establish
communication with the relay, relay ID, and communication baud rate and determine if the
relay is capable of Fast Meter. Enter Y to save port configuration changes at the final
prompt.
