4.1 INTERFACES
This section shows the three standard Discovery hardware configurations,
including all technical details like cable P/N’s, cable diagrams, jumper settings
etc. In Chapter 6 you can find the (optional) Ethernet configuration. The
hardware specifications are summarised in Appendix A,”Connector types and
pin definitions”.
There are three main configurations possible when connecting the standard
Discovery to a back office system:
1. Direct RS232 connection (see section 4.1.1;
2. Direct RS422 connection (see section 4.1.2);
3. Multipoint RS485 network configuration (see section 4.1.3).
It’s optional to use the Ethernet configuration (see Chapter 6).
Before connecting, determine the cable work needed (see the following
sections).
4.1.1 Direct RS232 connection (single unit)
The Discovery and the back office system are directly connected via an RS232
cable (see figure 4.1). When using a shielded cable the maximum cable length
is 15 m, otherwise the maximum cable length is 2 m. The cable will be supplied
and installed by the Scantech Distributor. See Appendix A for cable
specifications. For test and demo purposes a short RS-232 cable is available at
Scantech under P/N A361701.
