Note that Auto 485 is a single jumper. The second site is not in use. See

Figure 1 for the location of this jumper.

Power-On Tri-state (BlueStorm/SP models only, excludes BlueStorm/SP RJ-11)

BlueStorm/SP models offer a power-on tri-state similar to the Auto-485 mode listed above. The BlueStorm/SP implementation will tri-state ports configured as RS-485 full duplex. This is meant to ensure compatibility with our legacy Blue Heat/PCI cards.

Jumper J1 controls the power-on tri-state functionality. Install a jumper on the first location of the J1 in order to tri-state Port 1 at power-on, install a jumper on the second position for Port 2, etc. Ports will not come out of tri-state until the driver opens the affected port.

Half Duplex and Multi-drop Slave modes require you to select the appropriate mode via software. Please refer to the readme.txt files found in the appropriate directories on the BlueStorm/LP/SP/SP Opto CD.
