Writing Multiple Channels

The main screen’s drawing tools can draw on all eight

channels of the on-screen display. Table 6 shows the

buttons that enable or disable each channel. When the

program starts, channel 0 is automatically enabled. The

main screen has a diagnostic menu, with global set-

tings related to low-level register access. These set-

tings do not need to be changed.

MAX4358 Crosspoint Switch

The MAX4455 EV kit is designed for use with the

MAX4358 crosspoint switch. To control the MAX4358 EV

kit (included in the MAX4455EVSYS), choose the

MAX4358 crosspoint from the view menu (see Figure 5).

Each of the outputs has a drop-down combo box to

select an input signal. Each output can also be config-

ured for unity gain or a gain of 2V/V. The setup menu

lets you quickly disable all outputs, or quickly connect

each output to a preset input.

Due to space limitations, the MAX4358 EV kit provides

BNC connectors for only four of its 16 outputs and only

four of its 32 inputs. However, the entire chip is func-

tional, and the software allows control of all channels.

When expert mode is selected, the GUI provides con-

trols for all inputs and outputs, as well as exposing the

IC address pin controls.
