5.9 Equipment RS-485 (J10), Standard Backward Compatible Interface
The Equipment Multi-Drop, Full-Duplex, Bi-directional RS-485 Interface (J10) allows communication
between converters. Because the RS-485 Interface uses a master/slave (talker/listener)
configuration, the converter that is designated as the backup will automatically be established as
the master. Under normal RS-485 protocol, the master will poll a specific slave by address and
only then will the slave unit respond. The swapping of Transmit Data and Receive Data is
accomplished in the inter-converter cables, as the hardware interface is identical for all converters.
Refer to Table 5-5 for the connector pinout.
