56K Software Modem
The Modem Riser (MR) is a high-speed PC
communication peripheral which works
with AMC’97/MC’97 compliant codecs.
With this software modem, you can connect
your computer to a remote location, receiv-
ing data at up to 56 Kbps in V.90 or K56flex
modes.
Primary/Seconday MR
There are two types of modem risers: pri-
mary MR and secondary MR. In appearance,
the primary MR has a crystal onboard but
the secondary does not. If your motherboard
has an audio codec and no PCI audio chipset
onboard, you may use the secondary MR;
otherwise, you should use the primary MR.
1. Power OFF your computer.
2. Open the computer chassis and re-
move the metal plate on the AMR ex-
pansion slot.
3. Carefully align the MR card’s connec-
tor into the AMR slot and press firmly.
4. Secure the MR card onto the chassis
with the screw removed in step 2.
5. Connect the MR card’s LINE connec-
tor to a telephone wall jack. Connect
the PHONE connector to a telephone
(optional).
6. Replace the computer chassis.
