PanelView 300 Micro Terminal 13

Using the Communications Port
The PanelView 300 Micro terminal is available in 2 versions.
Both versions have an identical RS-232 communications port with a MicroLogix
8-pin mini-DIN style connector. The only difference is the protocol firmware
(DF1 or DH485) pre-loaded at the factory. Both versions of the protocol
firmware are supplied with the PanelBuilder32 software. You can change the
protocol by downloading the firmware to the terminal using the Windows
PanelView MotherBoard Firmware Download Utility (WinMBFWDL) utility.
This utility is included with the PanelBuilder32 software.
The following table lists the communication parameters supported by each of the
protocols on the RS-232 communications port.
