  • Page 14: Mechanical Mounting Of The Modem

    2.1 MECHANICAL MOUNTING OF THE MODEM The V.22/212A Modem Card must be installed in an enclosure suitable for the application. The modem can be installed using customer hardware or the factory mounting rails included in the installation kit 3-0447-005. When using customer hardware, mount the modem inside the enclosure with four 6-32 standoffs, using 6-32 screws and washers (internal-tooth washers are recommended).
  • Page 15 Install the modem to the enclosure with mounting rails as follows: 1. Clean the mounting area of the enclosure, using the alcohol swab included in the kit, then wipe the area dry with a clean towel before the alcohol film dries. 2.

  • Page 16: Electrical Connection Of The Modem

    V.22/212A MODEM CARD, ENSURE THE AREA IS NON-HAZARDOUS. The V.22/212A modem has three connectors: a telephone connector J6, a power connector J5, and a RS-232 connector J4. The telephone connector requires a standard miniature six-position RJ11C telephone plug. Only the TIP and RING lines are used, J6-2 and J6-3, respectively.

  • Page 17: Power And Control Connections

    2.2.1 Power and Control Connections The V.22/212A Modem requires 5 to 15 Vdc for operation. Power can be wired to the power connector J5 or through the RS-232 connector J4. Refer to Exhibit 2-2. When using the power connector J5, wire the positive lead to J5-1 and the negative lead to J5-2.

  • Page 18: Rs-232 Connections

    To conserve energy, the V.22/212A Modem provides a standby mode, configured by Jumper J2 (located near the telephone transformer T1). During standby mode, the modem draws 50 uA typically. When the modem receives a call or the MPC* control line (J5-3) is set low, the modem goes into an active mode and draws 60 mA typically.

  • Page 19: Modem Configuration Jumpers

    2.3 MODEM CONFIGURATION JUMPERS The Modem provides six hardware configuration jumpers. Refer to Exhibit 2-3. The configuration jumpers are described as follows: Exhibit 2-3: Modem Configuration Jumpers Constant Power Jumper: When installed, the modem is set to be constant powered. When removed, the modem remains in a stand-by power mode until the MPC* input (J5-3) is set low or the modem receives a call.
  • Page 20 J9 pins 1&3 and 2&4), the V.22/212A modem (remote modem) monitors the DCD signal of the received incoming call from a host modem. Five seconds after the DCD signal disappears (host modem disconnected), the remote modem disconnects. In the alternate twenty-minute operation (jumpers installed across J9 pins 3&5 and 4&6), the remote modem connects with an incoming call, then automatically disconnects twenty minutes later.

  • Page 24: Operating Modes

    3.2 OPERATING MODES The modem functions in one of two modes: Command Mode or On-Line Mode. Upon initialization, the modem enters the command mode of operation. During the command mode the modem operations are controlled by the AT commands. No data is being received or transmitted while in the command mode.
  • Page 25 ATE1 S0=3 <CR> or ATE1S0=3 <CR> In the previous example, the first command line includes a space between the commands (ATE1_S0=3), while the second command line does not (ATE1S0=3). The space between the E1 and S0=3 commands is not necessary, but makes it easier to evaluate the command line before activating it, especially for command lines including more than three commands (spaces are not counted as part of the 40 character maximum).
  • Page 26 ATIn The ID Code Command. The different values of "n" (0-4) provides ID codes, and various firmware and software data. ID Codes are identified as follows: Product Code (249). ROM Checksum. Checksum Test. Product Revision. Software Copyright. ATLn The Speaker Volume Command adjusts the modem's speaker volume (not required for this modem).
  • Page 27 ATXn The Result Code Command sets which verbose/numeric result codes are to be displayed. The "n" options are defined as follows: Result Codes enabled are OK/0, CONNECT/1, RING/2, NO CARRIER/3, and ERROR/4. Result Codes enabled are OK/0, CONNECT/1, RING/2, NO CARRIER/3, ERROR/4, CONNECT 1200 (baud rate)/5, and CONNECT 2400 (baud rate)/10.
  • Page 28 AT&Gn The CCITT Guard Tone Command selects one of several guard tones for the modem used in the CCITT mode (typically not used in the United States). Values for "n" are defined as follows: no guard tone. 1800-Hz guard tone. 550-Hz guard tone.
  • Page 29 Denies the local modem from participating in a remote digital loopback test initiated from a remote modem. Initiates a remote digital loopback test, checking the local computer, the local modem, the telephone lines, and the remote modem. When initiated, data entered from the local computer is transmitted through the local modem to the remote modem.
  • Page 30 AT&Xn The Sync TX CLK Mode Command determines the clock signal for transmissions when the modem is in synchronous mode (refer to the AT&M and AT&Q commands). The values for "n" are defined as follows: modem uses an internal clock. modem uses an external clock from the computer.
