Note:A total of 32 channel settings are available. The jumpers are a binary representation of the decimal addresses. JP1/A is the Most Significant Bit and jumper JP1/E is the Least Significant Bit. The jumpers have the following decimal values: JP1/E=1, JP1/D=2, JP1/C=4, JP1/B=8, JP1/A=16, . Open the jumpers and add the values of the jumpers that are open to obtain the correct channel. (Open=1, Closed=0)

The settings for JP2 through JP4 are identical to those for JP1. JP1 sets the FABB channel for serial port 1, and JP2 through JP4 set the FABB channel for serial ports 2 through 4, respectively.
