4.1.7.1.2. Closedown resistors with solding bridges
To be able to adjust the bridges of the closedown resistors of the CamCon 16 the device has to be
opened. The cover can be pushed appart in the middle with a screw driver. There are two soldering
bridges labled "TERM 485" on the soldering side of the largest circuit board. If these are closed, the
RS485 conduction is closed with a resistance of 390/150/390 Ohm. Both bridges have to be either both
open or both closed, since an asymmetrical charge disturbs the data transfer.
4.1.8. Clamping allocation of a serial RS232 interface (optional)
Since february 2002 CamCon DC16 may be equiped with an RS232 interface (optinal). The wiring
distance of this interface is limited to a maximum of 10 meters.
