Configuration Overview
Each ME475A-R2 SRM has three sets of eight switches, yielding 24 total DIP
switches. The three sets will be referred to as S1, S2 and S3. As Figure 2 shows, the
orientation of all DIP switches is the same with respect to “ON” and “OFF” positions.

2.2 CONFIGURATION SWITCH SET “S1”
The DIP switches on S1 set data rate, clock source, async./sync. mode and carrier
control method. The default settings are summarized in Table 1.
