Note that the Operational mode must be set to one of the LOCAL Modes (S1-1 UP) to allow the Remote
Master mode Select Input to operate correctly. Refer to the Set Up section on Remote Master Mode Select
Set Up.
 Set the data type for the Primary Data Port.
This is done on S1-3 thru 6 and S6-1 thru 4. Note that S1-7 is used for the Master Echo Cancel
Enable/Disable function, and must be disabled in RS485 2-wire. Insure that you have set the RS485 and
RS422 termination switches (S6-3 and S6-4) correctly. In general, the last unit on an RS485 and RS422
bus should have the terminators enabled by setting the switches down. Refer to Table 2 and the System
Architecture section for details on this function.
 Set the ECHO Cancel for the Primary Data Port with switch S1-7. The Echo Cancel function is affected
by Ring Timeout Settings on S-2. If the Data Tagging Feature is enabled (switch S1-10), the Echo will be
cancelled no matter how S1-7 is set. Refer to Table 2 and the System Architecture section for details on
this function.
