The TTL output

The TTL output

The instrument with RS485 on board does not need any kind of external interface module. For instruments with an external interface: keep the TTL cable away from power cables or frequency sources.

The XJ485 external interface must be connected with a TTL cable to the instrument with TTL compatibility.

Serial address of the instruments

Each instrument must be defined by its unique address.

Check the address into the Adr parameter value of each instruments. Take reference to the instruction manual of the instrument itself to find the right procedure to enter the programming and set the value.

The easiest way to work with the category functions is to set the addresses progressively for similar groups of instruments which have the same application.
