If the optional test module is used auxiliary power supply can be disconnected from
the device during the test to check autonomous power supply provided to the device from
current circuits.

3.5. External communication.
Configuration can be performed and monitored via a RS232 (Z52) connector
included as standard. A proprietary protocol is used for communication from the level of
software provided with the AZT-9. External communication capabilities can be expanded
through installation of the MGB-9 hub module available in several versions. Depending on
requirements it comes with RS232, RS485, optical or Ethernet ports (see the table below).
As standard each communication channel simultaneously supports the following protocols:
proprietary ZPrAE (ZP6) and IEC-60870-103. The F1 version of the MGB-9 module allows
for communication over the IEC-61850 protocol. The MGB module requires auxiliary
voltage to work.
