10.3.1 REFERENCE EX CHAN GE / Reference exchange slave ratio PIN 189
Note. In SLA VE mode, when data is received, it initiates an immediate transmit of its own GETFRO M data.
10.3.2 REFERENCE EXCH ANGE/ Reference exchange slave sign PIN 190
Note. In SLA VE mode, when data is received, it initiates an immediate transmit of its own GETFRO M data.
10.3.3 REFERENCE EXCH A NGE / Reference exchange slave monitor PIN 191
In M ASTER mode the receive channel still accepts data. E.g. A MASTER unit can borro w a SLA VE unit block.
10.3.4 REFERENCE EXCH ANGE / Reference exchange master monitor PIN 192
Note. In M ASTER mode the unit initiates transmission. In SLA VE mode transmission is initiated by reception.
10.3.5 REFERENCE EX CH A NGE / Reference exchange master GET FROM
This is the data that will be transmitted by a master, and by a slave in response to receiving data. Hence to
cascade units there is one MASTER feeding the first SLA VE, then the first SLA VE feeds the second SLA VE
etc. The data being received in each unit is connected internally by the REF EX CH SLA VE GO TO in the
BLO CK OP CONFIG menu. The data being sent to the next unit is determined by this GETFRO M
