Modem Riser

7.2.3 Hardware Installation Procedure

7.2 Modem Riser (optional)

7.2.1 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 com-

puter to a remote location, receiving data at

up to 56 Kbps in V.90 or K56flex modes.

7.2.2 Primary/Seconday MR

There are two types of modem risers: primary

MR and secondary MR. In appearance, the

primary MR has a crystal onboard but the sec-

ondary does not. If your motherboard has an

audio codec and no PCI audio chipset on-

board, you may use the secondary MR; oth-

erwise, 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 to 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.
