Protocol Selection
Jumper B10 selects between 2-pass and 4-pass communications protocol. The 2-pass protocol is
the recommended protocol because it provides faster and more efficient communications. The
4-pass protocol is mainly for use as a troubleshooting aid. When jumper B10 is installed, 2-pass
protocol is selected. The unit can be put into a 4-pass mode by removing the B10 jumper or using
the Optomux software command “E.”
Address Selection
Jumpers B0 through B7 select the Optomux address. Each Optomux unit on the same network must
have a unique address (different from all the others). Addresses are arbitrary and do not need to be
sequential (although they must be unique). The following table lists the possible addresses with
corresponding jumper configurations. To use the table, find the address you wish to use (0 to 255).
To the right of the address is the sequence of jumpers in the following order: B7, B6, B5, B4, B3, B2,
B1, and B0.
