APPENDIX B
CONNECTION INTERFACES USED WITH EACH SERIES
PTX_LCD
Devices from the PTX_LCD series offer two interfaces to connect to DB2003 – I
2
C bus and
RS232. The REMOTE connector, type DB15 must be used for an I
2
C connection. Use “Cable 3” (see
“APPENDIX A” on page 49) . If you connect multiple devices on the I
2
C bus, each device must have
a unique address. In the device screen menu, under the “General Set” page, the parameter is named
“UART Adr.”. The same value is used for the I
2
C bus address. In the DB2003, it is designated “Bus
Address” and is valid for all interfaces.
The RS232 connection can be made in two ways. On the PTX_LCD side, you can use the RS232
connector, type DB9. On the DB2003 side, you can use the COM1 connector and a straight cable, as
described in “APPENDIX A” - “COM1 Connector” . The second way is to use the COM2 connector
and “Cable 1” . When 2 devices are connected via RS232 (on COM1 and COM2), they can use the
same address value. It is important to set in both DB2003 and PTX_LCD the same values for Bus
Address and for Bus Speed.
PTX_DDS and PTX_LCDDSP
Devices from this series use only an RS232 connection and it can be made in two ways. On the
PTX_DDS/PTX_LCDDSP side, use the RS232 connector, type DB9. On the DB2003 side, you can
use the COM1 connector and a straight cable, as described in “APPENDIX A” - “COM1 Connector” .
The second way is to use DB2003 connector COM2 and “Cable 1” . When 2 devices are connected
via RS232 (on COM1 and COM2), they can use the same address value. It is important to set in both
DB2003 and PTX_DDS/PTX_LCDDSP the same values for Bus Address and for Bus Speed.
Devices from the PTX_DDS and PTX_LCDDSP series have a REMOTE connector but it cannot
be used with the DB2003.
TEX_LCD and Blues
Devices from the TEX_LCD and Blues series use only an I
2
C bus connection, using the REMOTE
connector, usually type DB15. Use “Cable 3” . If you connect multiple devises on the I
2
C bus, each
device must have an unique address.
Devices from the TEX_LCD and Blues series have an RS232 connector but it cannot be used with
the DB2003.
PJ Amplifiers
Amplifiers from the PJ series use only an I
2
C connection. Usually, the connector is of the DB9
type and is designated ‘I
2
C BUS’. Use “Cable 3” from “APPENDIX A” . If you connect multiple
devices on the I
2
C bus, each device must have an unique address.
PJ amplifiers have an RS232 connector but it cannot be used with the DB2003.
