1. Si2493/57/34/15/04-EVB Setup and
This section explains how to set up the Si2493/57/34/
15/04-EVB for evaluation as an RS-232 or USB
interface modem. Jumper settings, power connection,
PC/terminal
configuration settings are given. The initial modem
setup after power is applied as well as a basic tutorial
on modem operation are provided. Si2493/57/34/15/04-
EVB configurations for evaluating additional features
are discussed separately. See the Si2493/57/34/15 or
Si2404 data sheets and “AN93: Si2493/57/34/15/04/04
Modem Designer’s Guide” for complete details.

1.3. Jumper Settings
Check all jumper settings on the Si2493/57/34/15/04-
EVB before applying power. The standard factory
jumper settings for the FT package are shown in
Figure 1; the FS package is shown in Figure 2. These
settings configure the Si2493/57/34/15/04-EVB for RS-
232 serial operation with autobaud. Any standard
terminal program configured to communicate through a
PC COM port can be used to communicate with the
Si2493/57/34/15/04-EVB. The standard factory jumper
settings for USB operation with the FT package are
shown in Figure 3; the FS package is shown in Figure 4.
The only difference between RS-232 and USB jumper
settings is that JP5 must be installed to enable USB.
