Scantech-ID Discovery SG-20 111
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!
