NORDAC SK IC1-232/485 Operating Instruction
BU 0010 GB Technical design subject to change 3
Terminal resistor
A terminal resistor can be switched on at the
interface converter using a dip switch. This terminal
resistor is switched off as default setting. The dip
switch position “ON” corresponds to a switched-on
terminal resistor of 120
Ω.
(DIP switch Æ See Figure P. 2)
Supply voltage status
As soon as the +5V supply voltage of the interface
connector is on, this status is displayed by a green
LED.
(Current consumption of the converter: 100mA)
Information
The channel switching of ‘send’ and ‘receive’ occurs automatically.
Accessories
External supply cable 5V:
A +5V supply voltage is required for connecting the p-box to
a PC/laptop in combination with the interface converter. This
can be provided by an additional connecting cable. The
cable is connected to the USB port of the PC/laptop.
When using the interface converter on the frequency
inverter, this takes its supply voltage directly from the
frequency inverter and does not therefore have to be
supplied externally.
Attention:
It is important to ensure that there is only one supply voltage for the interface
converter. Otherwise this can cause damage !!!
When using the frequency inverters vector mc, SK 300E and SK 700E a supply
voltage of +5V is already available. An external supply cable for the USB connection
is not required in this case.
