Communications Port Hardware
The MSI-8000 RF Remote Display RS-232 communication port is used for software updates, connecting to a
remote display and for connecting to any RS-232 device.
Connector: M12 industrial IP67 rated. An adapter cable (PN 150964) is required to connect the MSI-8000 RF
Remote Display to a computer. This adapter cable converts the 8000 connector to a standard D9 serial connector.
The 503489 cable can be converted to DTE by using a Null Modem adapter.
Data Configuration: The data output is fixed at 8-1-N.
Baud Rate: Programmable for 300 to 230.4 k baud in 8 steps. The
bootloader for updating software is always 38.4 k baud
Handshaking: No hardware handshaking is supported. Xon/Xoff
software handshaking is always on.
This configuration plugged into a standard DTE connector disables
Comm Port 2. Turn Comm Port 2 off using the Comm Port menu.
An unterminated cable is available (PN 143348) for wiring a
connector to the M12 connector found on the MSI-8000 RF Remote
Display.
The following diagrams show how to wire standard D9 connectors to
access Communications Port 1 or Communications Port 2.
