If you are using RS485 mode (SW1 and SW2 are closed) and you want to terminate
the RS485 bus, then you only need to close either SW5 or SW6. Having both
switches closed will effectively add two termination circuits to the same bus!
TB1000 Terminal Block Adaptor
The TB1000 terminal block adaptor is designed to be used with DS1000, DS1002,
and DS1003 devices (or IB1000, IB1002, and IB1003 boards). This adaptor
"converts" DB9 connectors of the DS1000, DS1002, and DS1003 into 9-terminal
blocks of "spring clamp" type. These are convenient for attaching wires, which is
very useful for industrial installations.
Each terminal of the terminal block connects directly to a pin on the DB9 connector.
Pin numbers on DB9 connectors and terminal blocks match exactly. Therefore,
terminal assignment on each terminal block is as follows:
