2.3 Installation
Perform the following procedure to install modem cards in the CC916, CC1416, CC2816 or CC1600
racks*. The installation process involves:
1. Power cord must be unplugged prior to installation of the Power Source(s). Insert Power
Source(s) (PS216A or PS1600) into far right of the rack cage.
2. Slide a modem card into one of sixteen available modem slots. Start by inserting a modem into
the left-most channel (slot #1) of the rack. The toggle switch should be at the bottom of the card,
with the component side of the card facing the right. The modem’s gold edge connector is offset
so that the modem cannot be inserted incorrectly. Continue installing modem cards as
necessary.
3. Plug RS232C Cable into appropriate modem slot (DB25/25-pin connector-female) at rear of rack.
Note: Any cables connected to the computer must be shielded to reduce interference.
4. If you are connecting your phone line directly to the modem card, plug the phone line cable into
the appropriate modem slot (DB9/9-pin connector-female) at the rear of the rack and the other
end into the phone-company-provided RJ11 or RJ11W modular phone jack. To connect the
modem to the phone lines using an CC1600 modem rack, plug one end of the RJ11 cable
provided with the modem into the rack's RJ11 connector (located on the back plane of the
modem rack) and the other end into the phone-company-provided RJ11 or RJ11W modular
phone jack.
5. Plug in modem rack power cord.
6. Verify remote modem's current configuration settings with your MT2834BLR in terms of data
compression, error correction, transmission rate, etc. (ATL5/ATL7 Command--see Chapter 4 on
AT commands).
7. Attach MT2834BLR to dial-up phone lines and/or leased lines and verify DIP-Switch #10 and #5
settings (Section 2.5).
8. Make sure modem and computer/terminal serial port baud rates are adjusted (Section 2.5).
9. Set both local and remote modems to either Normal (&E0&W0) mode or to Reliable (&E2&W0)
mode.
10. Verify leased line transmit level (DIP-Switch #3) setting (Section 2.3.1).
11. Proceed to Chapter 3 of this manual, or to your data communications software manual.
*Multi-Tech offers several types of modem racks. All Multi-Tech rack-mounted modem cards (except
MT1432/2834MR) are interchangeable among all types of modem racks. There is, however, slight
LED indicator differences. Model #CC216G is a “generic” modem rack for any rack mount modem
card. The user affixes LED labels on a per slot basis depending on modem type.
