NSG 5500 Automotive transient immunity generator
2.9 Installation / set-up control unit (CTR)
There are three controllers in circulation: The CTR 5500 and CTR 5501/02. The CTR 5501/02 has some small
changes: it supports a new USB connection and has a new method of updating the firmware.
2.9.1 Setting the IEEE address
2.9.1.1 IEEE address setting CTR 5500
When communicating with the NSG 5500 via the IEEE 488 Interface it is necessary that the address set in the
AutoStar comm setup screen corresponds with the IEEE 488 address set on the control unit.
A DIP switch array on the front panel of the control unit is used to set the NSG 5500 IEEE address. There may be
five or six switches on this DIP switch, depending on the hardware version. Only the first five switches are used.
These first five switches correspond to the binary weighted address values 1, 2, 4, 8, and 16. The total sum
of the values corresponding to the switches in the “ON” position is the IEEE address. For example, in the
illustration below, the address set is 1 + 2 + 8 = 11.

NOTE!
The address is read only at power on. Therefore, after changing the address
setting, the NSG 5500 must be powered off and then on to accept the new setting.
The hardware is set at the factory to address 1. This is also reflected in the Auto
-
Star setup.
CAUTION!
The IEEE Bus has proven to be a very reliable control method in industrial envi
-
ronments. However, the CTR 5501/02 supports also USB control. Please note that
USB can be affected by disturbances in typical EMC laboratories. For this reason,
please use only the supplied USB cable.
Only cables confirming to the USB 2.0 standard and above are supported. Even so,
in very noisy environments, the IEEE 488.2 connection is recommended.
