About the interface cards

5. Usage in devices of the series

EL3000/EL9000

The electronic loads of the series EL3000 and EL9000 sup-

port the following interface cards:

IF-U1, IF-R1, IF-C1, IF-G1

Note about the GPIB card IF-G1: at devices with firmware

version 2.11 or older the card is detected as IF-C1 (CAN

card) and must be configured to following settings:

- CAN Baudrate: 100kBd

- Bus termination: no

- Relocatable ID: 0

Also, in devices with firmware version 2.14 or lower, the

card is not correctly supported. We recommend an update.

Please contact your dealer.

At firmware version 3.01 or higher there are no limitations.

The general functionality of the interface cards is the same

if used in a power supply. The amount of features is limited,

but also different.

Please refer to the previous sections for detailed information

about the interface cards.

You can configure the interface cards in the setup menu of

the devices. This is activated by turning the switch Level

Control to position Setup.

Depending on which card is equipped (the electronic loads

feature only one card slot) a different selection of parameters

is available. The parameters and their values are identical to

the ones explained in section 4.1 to 4.3, with the exception

that no Sample point can be set at CAN.

There are also no settable parameters for the USB and

IEEE cards.
