1200 BPS DC-2212 Modem (260-1176)      Cables          Faxback Doc. # 5682

Tandy's DC-2212 intelligent modem is Bell System 103/113 and 212A compatible,
connecting to telephone lines via modular connector. The RS-232 input/output 
of the modem interfaces directly with the RS-232C-equipped TRS-80 computers.

CONNECTING TO THE TELEPHONE

The type of wall connection is important in determining how the DC-2212
modem is to be connected.

FOR A SINGLE-LINE CONNECTION:

1. Remove your telephone's plug from the modular wall jack and insert it in
   the PHONE jack on the rear of the modem.

2. Plug the modem's line cord into the modular wall jack.

NOTE: For a four-prong wall connection, you will need an adapter (279-360)
suitable for the older style wall connector.

If your telephone is wired directly to the wall, contact the telephone 
company to have modular connections installed.

FOR A MULTI-LINE CONNECTION:

The DC-2212 modem can be used with a multi-line telephone, but you may need
a multi-line adapter (43-270/271), a hardware modification to the modem, or
both.

CONNECTING TO A POWER SOURCE

Insert the AC adapter's plug into the AC POWER jack on the rear of the modem. 
Plug the adapter into an electrical wall outlet or an approved power strip.

Be sure to connect the adapter to the modem before you plug the adapter into
the wall outlet. Otherwise, damage to the adapter could result.

IMPORTANT NOTE: Use the supplied UL-Listed adapter only. Another type of
adapter could damage the modem.

nect to your computer. The following table provides the cable catalog
