Exhibit 2-1: V.22/212A Modem PCB Dimensions
In the V.22/212A Modem Installation Kit (3-0447-005), the modemis factory installed to mounting
rails using 6-32 screws and internal-tooth washers. The factory mounting rails secure the modem
inside an enclosure using double-sided, high-performance, VHB tape. Do not remove the
protective paper from the VHB tape until it is time to install the assembly to the enclosure.
When selecting a mounting area in the enclosure ensure there is adequate clearance for the modem
connectors.

7
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. Remove the protective paper from the VHB tape. Ensure nothing contacts the tape
until put in place.
3. In one motion, set the modem with mounting rails in place and press down hard on the
four mounting screws of the board, securing the unit to the enclosure. Once the VHB tape
has made contact to the mounting area, do not remove it, not even temporarily.
Removing the unit from the mounting area degradesthe adhesive strengthof the tape,
requiring the tape to be replaced.

2.2 ELECTRICAL CONNECTION OF THE MODEM
When installing the V.22/212A Modem Card in a hazardous location, wire all circuits connected to
the modem using Class-I, Division-2 wiring methods as specified in Article 501-4(b) of the National
Electrical Code, NFPA 70, or in Section 18 of the Canadian Electrical Code, Part 1.
WARNING:
BEFORE CONNECTING OR DISCONNECTING THE
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.
All wiring connections to the power connector J5 terminate in cage-clamp screw terminals that
accept stranded-wire sizes to 14 AWG. Strip the wire ends approximately 3/16 of an inch. Inspect
the stripped wire for nicked and frayed ends. Insert the stripped wire completely in the clamp, then
tighten the clamp using a small common screwdriver. Inspect each connection, ensuring no frayed
strands protrude and no insulation is in the clamp.
The RS-232 connector J4 mates to a 25-position DB25P connector. After the connectors are mated,
secure the connection with two 4-40 screws.

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.
Configuration Jumper J7, located between the power connector and the RS-232 connector, is not
necessary and can be removed.
9
When routing power through the RS-232 connector J4, wire the positive lead to J4-9 (PTV) and the
negative lead to J4-7 (SG). Configuration Jumper J7 must be installed for this mode of operation.
Exhibit 2-2: Power Connection Options
WARNING:
CONNECT THE MODEM GROUND TERMINAL (E1) TO
THE CLOSEST COMMON EARTH GROUND
CONNECTION OF THE INSTALLATION BEFORE
MAKING ANY OTHER CONNECTIONS TO THE
MODEM.

10
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. When jumper J2 is installed, the modem is
constantly powered in the active mode. J2 must be removed for standby operation.
If the customer requires dial-out capabilities of the modem, the modem must be constant powered
(J2 installed), or use the MPC* input to place the modem in the active mode(J2 removed). Wire the
MPC* control line to the power connector J5-3. The line must be referenced to the ground of the
modem (J5-2 or J4-7).
2.2.2 RS-232 Connections
The V.22/212A Modem uses RS-232 communications to serially transfer data between the modem
and the customer's equipment. The RS-232 connector (J4) provides the following RS-232 pin
assignments for connection to customer's equipment:
J4-Pin Signal Signal Description
1 FG Protective Ground
2 TX Transmit Data
3 RX Receive Data
4 RTS Request To Send
5 CTS Clear To Send
6 DSR Data Set Ready
7 SG Signal Ground
8 DCD Data Carrier Detect
9 PTV Power Input
20 DTR Data Terminal Ready
22 RI Ring Indicator

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
J2 ConstantPower 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.
J7 RS-232 PWR Jumper: When the alternate power connection is made through the RS-232
connector (J4), this jumper must be installed. Remove this jumper when the primary power
connection is made through the power connector (J5).
J8 Memory Write-Enable Jumper: This configuration jumper provides a hardware safety
feature, preventing the non-volatile memory frombeing overwritten when an AT&Wx or an
AT&Zn=s command is accidently issued to the modem. To change the contents of the non-
volatile memory (destroying the old data), jumper J8 must be installed before issuing the
AT&Wx or AT&Zn=s command. This jumper is not normally installed.
11
J9 Delay Select Jumpers (5 Sec./20 Min.): In the normal five-second operation (jumpers

12
installed across 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. This is useful in remote locations where excessive line noise of very poor
phone lines may be interpreted as a false DCD signal, keeping the remote modem connected.
J10 Unqualified RX Enable Jumper: In the qualified-mode setting (jumper removed), the
DCD signal from a received call enables transfer of data from the device connected to the
modem's RS-232 port. Dialout capabilities of the connected device is disabled; the device
can only respond to a request of data from a received call.
In the unqualified-mode setting (jumper installed), the device connected to the modem's RS-
232 port can transfer data to the modem without the DCD qualifier, allowing full dialout
operation.
J11 Dumb Mode Jumper: When installed, the modem is set in a mode of operation which
provides only for the input and output of data to and from the device connected to the
modem's RS-232 port, disabling all other programming functions. This jumper is not
normally installed.
