2.3. Jumper Settings
Check all jumper settings on the Si2400URT-EVB
before applying power. Figure 1 shows the standard
factory jumper settings. These settings configure the
Si2400URT-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 Si2400URT-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.
Should echo “AT” and then an “O”.
ATS14=20 to enable +++ escape.
ATS07=06 to enable V.22b.
ATS00=01 for auto-answer on first ring.
