Return the relay to service by setting cell [0F0E: COMMISSIONING TESTS, Test Mode] to
‘Disabled’.
4.2.9 Rear Communications Port
This test should only be performed where the relay is to be accessed from a remote location
and will vary depending on the communications standard being adopted.
It is not the intention of the test to verify the operation of the complete system from the relay
to the remote location, just the relay’s rear communications port and any protocol converter
necessary.
4.2.9.1 Courier Communications
If a K-Bus to RS232 KITZ protocol converter is installed, connect a portable PC running the
appropriate software to the incoming (remote from relay) side of the protocol converter.
If a KITZ protocol converter is not installed, it may not be possible to connect the PC to the
type installed. In this case a KITZ protocol converter and portable PC running appropriate
software should be temporarily connected to the relay’s K-Bus port. The terminal numbers
for the relay’s K-Bus port are given in Table 7. However, as the installed protocol converter
is not being used in the test, only the correct operation of the relay’s K-Bus port will be
confirmed.

Table 7 - RS485 Terminals
Ensure the communications baud rate and parity settings in the application software are set
the same as those on the protocol converter (usually a KITZ but could be a SCADA RTU).
The relay’s Courier address in cell [0E02: COMMUNICATIONS, Remote Address] must be
set to a value between 0 and 255.
Check that communications can be established with this relay using the portable PC.
