Setting the DIP Switches
The DIP switches, located on the rear panel between the RS-232
and Telco ports, are for adapting the modem to your equipment
and system requirements. Each set of DIP switches controls 8
modems.
Figure 2.3 shows the DIP switches in their factory default
settings, which reflect typical system requirements such as:
Auto Answer enabled, no result codes, no Data Terminal Ready
or Carrier Detect override. See Table 2.1 for switch options to
decide if the factory settings need to be changed.

Cabling
1Make sure that the unit’s power switch on the rear panel is
OFF.
2. Connect the modems to telephone lines. For each modem, plug
one end of an RJ-11 telephone cable into a Telco jack on the
rear panel of the unit. Plug the other end into a Telco jack.
Note: Do not confuse the RJ-11 and RJ-45 cables. They look
alike, but RJ-45 cables have more pins than RJ-11 cables: RJ-
11 cables have 4 pins where RJ-45 cables have 8 pins.
3. Connect the modems to terminals. The final step is to connect
the RS232 jacks to the computer or terminal equipment.
a. Connect one end of an RJ-45 cable into each of the RS-
232 jacks on rear panel of the unit.
b. Adapters—since the terminal’s RS-232 jack probably does
not fit with RJ-45 cables, this connection requires an
adapter. Depending on a system’s cabling needs, there
are cable kits available with either RJ-45 to DB-25 or RJ-

Installing the MP/8 V.34 2-7
45 to DB-9 adapters. Use these to plug the cable into the
terminals or network.
4. Plug the power cable into the power jack at the back of the
unit. Plug the cable into a standard 115-volt AC wall
socket.
5. Power on the unit. The Run/Fail LED should emit a green
light. If it does not indicate that the power is on, make sure
the power cable is attached tightly and the power switch is
on.

Configuring the Modems
Total Control MP modems are factory configured to run under
hardware flow control. Once the unit is set up, nothing else
needs to be done—the unit is all ready to operate. However,
the modems can be configured for specialized systems or
situations.
The modems use a superset of the standard AT command set
for dial-up modems. The commands control configuration
options as well as modem operations such as diagnostic testing.
Typically, you’ll need to directly command the modems only
for initial configuration, and to write that to Non-Volatile
Random Access Memory (NVRAM) with the commands. After
that, the modems will perform without operator intervention.
This chapter covers:
ROM Templates
Default—Hardware Flow Control Template
Low Performance Template
Software Flow Control Template
Accessing the Modems
Changing the Default Settings
Custom Settings in NVRAM
Using S-Registers
Templates
Read Only Memory (ROM) templates in the MP modems
contain settings for configuration commands and S-Registers
that control the way the modems operate. By tailoring any one
or more of these, the modems can be programmed to meet
specific communications needs.

3-2 MP/8 V.34: Getting Started
Default—Hardware Flow Control Template—&F1
When the Total Control MP is first turned on, the modems
automatically load the hardware flow control template into
active RAM from Non-Volatile Random Access Memory
(NVRAM). The Hardware Flow Control template, though
stored in ROM, is also stored in NVRAM as the current settings.
Unless a modem is programmed for another template, it will
operate under this configuration.
In this configuration, the modems are set to operate with
hardware flow control, a fixed serial port rate using the highest-
level result codes.
The modem drops the Clear to Send (CTS) signal it has been
sending to the computer or terminal when the modem's buffer
nears 90% capacity. It starts sending CTS again when the buffer
is about half full.
Table 3.1 on the opposite page shows the configuration
command settings under the hardware flow control template.
Recommended Uses
This template is the most compatible and is recommended for
all systems and software that support Request to Send and
Clear to Send hardware signaling, and a fixed serial port rate to
provide flow control. It offers the greatest efficiency and
reliability. If your system requires software flow control, your
best bet is to use the Software Flow Control template described
next.
If your system supports hardware flow control, you may wish
to review the descriptions of the other templates, or go directly
to Accessing the Modemslater in this chapter.
