Adding PAD modules to your Dewtetron system:
PAD modules can be plugged directly into the DEWE-3210, because it has 8 slots for DAQ/PAD/HSI series
plug-in modules. But if you don’t want to give up one of these eight dynamic input slots, you can simply add
a DEWE-30 series chassis.
This method also allows the DEWE-3211 to utilze PAD series modules, since this model does not have any
slots on its chassis. When only PAD modules are installed into it, the DEWE-30 series expansion box con-
nects easily via either RS485 connected to the Dewetron chassis’ EPAD interface, or via RS232C using the
Dewetron chassis’ COM port. DEWE-30 chassis are available with 4, 8, 16, 32, 48, or 64 slots.
- Note: if you want to also use DAQ or HSI series modules in this expansion rack, then you must also have an
analog cable connecting it to the DEWE-3210 or DEWE-3211. In addition, there must be an A/D card inside the
DEWE-321x chassis with the appropriate number of ADCs available.
Typical hook-ups
PAD modules can plug directly into any DEWE system that has DAQ/PAD/HSI slots, or...
PAD modules can plug into a DEWE-30 chassis, and connect to a DEWE system via RS485 (always avail-
able on the EPAD connector in any DEWE mainframe)
When using PAD modules simply with a computer (not a DEWE computer), you can use the RS232 se-
rial interface on the back of the DEWE-30 chassis to connect to your computer. If your computer does not
have RS232, you can obtain and use an RS232 to USB converter that will create a virtual com port on your
computer.
Do not connect both RS232 (USB) and RS485 interfaces at the same time.
If using RS232 com port, you must congure the port used for additional PAD modules in the DS-7 hardware
setup, analog tab.
Make sure that PAD modules are check-marked in the HARDWARE SETUP SCREEN when using DS-7
software
When adding external PAD modules, enter the number of them under “Additional PAD modules”
If adding a DEWE-30 via RS232, select the appropriate com port here for the additional PAD modules.
