4.6.4 DIP Switches of Subboard
The E8IT subboard (IMA service subboard) is of two types: E8IT.2 REV.0 and E8IT.2 REV.A.
The E8IT.2 REV.0 subboard supports only the 75-ohm coaxial cable. The E8IT.2 REV.A subboard supports both the 75-ohm coaxial cable and the
120-ohm twisted pair by setting the DIP switches.
Both types of E8IT subboards have five sets of DIP switches (S1–S5), where,
S5 has four bits. S1, S2, S3, and S4 have eight bits each.
The port impedance of the E8IT.2 REV.0 is 75 ohms by default, you need not configure it.
Table 4-14 describes the settings of DIP switches.
