2.3. Jumper Settings
Check all jumper settings on the Si2401FS10-EVB before applying power. Figure 1 shows the standard factory
jumper settings. These settings configure the Si2401FS10-EVB for RS-232 serial operation. Any standard terminal
program configured to communicate through a PC COM port can be used to communicate with the Si2401FS10-
EVB. To connect the modem directly into an embedded system with LVCMOS/TTL levels, install JP8 to disable
both the RS-232 and USB interfaces. Connection to the embedded system can be made to JP-3. Place a jumper
on JP13 to enable the onboard speaker, LS1.
