Why do I sometimes encounter connection problems?

Check for the right jumper settings. Is the right type of cable used and the max.

length not exceeded? Check the wiring of the cable, connect (as described in the

manual) only the required lines, leave other pins open.

RS-422

How many Discoveries can be connected under RS-422?

In principle one, by applying additional COM ports on the Back Office computer

system you can increase this quantity.

Ethernet

TCP/IP: What length of cables can be used?

In principle ‘limitless’. Ask your network administrator.

Wireless Networking, RFDC

Which Wireless options are available?

The field of wireless data transfer is developing continuous.

Our wireless SG-20 is WiFi compatible (IEEE802.11b) and will follow general

developments of WiFi.

Generally spoken it can be seen as wireless Ethernet. Newer units may be

ordered with an RFDC interface (Radio Frequent Data Communication). Retrofitting

of units with a partnumber of A360104 or lower, is not possible.

H-6

SG-10 COMPATIBILITY

Can the Discovery SG-20 be combined with or joined in an existing SG10 RS-485

network?

Yes, the SG-20 can be configured to be fully compatible with the SG10, just by

setting it in SG-10 mode by means of the buttons.

It is obvious that you limit the displaying possibilities i.e. having only 2 lines

available (in SG-10 mode), rather than the 8 display lines available in SG-20 mode!

At the same time: You cannot download of use bitmap images on the Discovery

screen
