On the front panel of the modem, there are:
c
One Power LED and six status LEDs (see page 21)
c
A rotary test switch (see page 22)
On the back panel of the MOT202TSA modem, there are:
c
A power cord or power input connector
c
A power switch for turning the modem on and off
c
A fuse, 3/8 amp, 250 Volt, slow-blow
c

Configuring the Modem
The modem obtains some operating characteristics from jumper
settings. The default jumper settings are for common 4-wire full-duplex
applications. To reconfigure the modem for 2-wire half-duplex and
special applications, you must change the default jumper settings.
To change jumper settings, push the two tabs on the back of the modem
to open the modem cover and gain access to the jumper settings on the
printed circuit board (see Figure 2-3). Then set the jumpers to the
desired settings and replace the cover.
Figure 2-3. Gaining Access to the Modem Jumpers
Figure 2-4 on the next page shows the location of the modem jumpers.
Table 2-1 on page 13 summarizes the jumper settings (default settings

position of the jumpers on the modem board when you face
the board as indicated in Figure 2-4 on page 12.
Jumper S1 − Carrier Detect Control
Settings:
-33 dBm (
-43 dBm
Jumper S1 configures the dynamic range of the modem receiver. The
selections are either –33 dBm or –43 dBm. If the incoming signal is
above –24 dBm, use the default –33 dBm setting. If the modem is
operated on the network, use the –43 dBm setting.

level of 0 dBm.

Jumper S3 − 2-wire/4-wire Mode
Configuring the Modem
Settings:
2-wire
4-wire (default)
Jumper S3 configures the modem for 2-wire or 4-wire operation.
c
When configured for 4-wire full-duplex operation, jumper S5 can
be strapped to maintain constant carrier from the master modem to
all slave modems at all times after the initial training. This enables
the master modem to transmit data to the slave modems, with no
RTS-to-CTS delay. This is the preferred operating mode when
minimum turnaround is desired.
c
When configured for 2-wire half-duplex operation, the modem
encounters an RTS-to-CTS delay when transmitting to slave
modems, increasing the turnaround time. Set jumper S5 to
controlled carrier for 2-wire half-duplex operation.
Jumper S4 − Call Turnaround Squelch
Settings:
Enabled
Disabled (default)
Jumper S4 configures the modem’s Call Turnaround Squelch setting.
For 2-wire, half-duplex communications, set this strap to the Enabled
position. In this position, the receiver is inhibited for a period of time
after the local transmitter is turned OFF. This guards against echoes
caused by the transmission just completed. The time is determined by
the turnaround squelch time option (jumper
S11
).
For 4-wire, full-duplex communications, keep the jumper set to the
default position of Disabled.

Jumper S5 − Transmit Carrier
Settings:

)
Jumper S5 places the transmitter under terminal control (default) or
turns on the transmitter continuously in a 2-wire half duplex system.
Jumper S6 − Local Copy
Settings:
Jumper S6 must be left is the default position of Disabled when
operating on a 4-wire network. It is also normally left in the default
Disabled position when operating on a 2-wire network. Strapping this
jumper as Disabled inhibits the local receiver from receiving the
transmission of the local transmitter.

Jumper S10 − Carrier Detect Delay
Settings:
Jumper
S10
configures the modem’s Carrier Detect turn on Delay
timing. The delay chosen must be consistent with the Clear To Send
delay selection of the transmitting modem and must be less than the
CTS delay. The available delays are 6 ms (default) and 23 ms. The
carrier detect drop out is less than 6 ms.

applications to prevent a malfunctioning slave from occupying the line
indefinitely.
When anti-streaming is active, the modem can only transmit data for up
to 56 seconds. Thereafter, the modem’s transmitter is automatically
turned off. The modem then looks for an ON-to-OFF transition of
Request To Send (RTS) before proceeding with normal operation.

Troubleshooting
Front Panel Test Switch
The modem front panel has a five-position rotary switch that lets you
select the modem’s operating mode. The five switch positions are:
c DATA
c AL
c DL
c ST
c TTP
use this position for normal data transmissions.
(Analog Loopback) this position prepares the modem for
testing by the local terminal device. The transmitter output of the
modem is disconnected from the output coupling transformer and
connected to the modem receiver input. See Figure 3-1.
(Digital Loopback) this position configures the modem to
loop back received data to the transmitter and transmit the data to
the remote end. The RS-232-C interface to the terminal is not
active during this test. See Figure 3-2.
(Self Test) this position inhibits the modem from
transmitting and receiving data on the COMM LINE. The RS-232C interface to the terminal is not active during this test. See Figure
3-3.
The test pattern (dot pattern) passes through the transmitter, loops
back into the receiver, is demodulated, and is checked for errors. If
errors occur, the TM LED turns OFF and remains OFF for a period
of time that depends on the pattern generator baud rate.
In Analog Loopback and Self Test modes, the received analog data
is buffered, amplified by 16 dB (if output level is set to 0 dB), and
routed out on the transmit analog pair.
(Transmit Test Pattern) this setting forces the transmitter
on and transmits data from the test generator to the COMM LINE.
The RS-232-C interface lines (RTS, CTS, and Transmit Data) to
the transmitter are not active. See Figure 3-4.
The TM LED goes ON when the receive data is good. If there are
errors, or if the received data does not compare with the
transmitted data, the TM LED goes off. The RS-232-C interface
lines to the receiver are active during this mode.

Troubleshooting
his chapter describes troubleshooting procedures you can use in the
unlikely event you encounter a problem with your modem.
Local Modem Test
The local modem test verifies the local modem’s transmitter, receiver,
and connection to the locally attached DTE. This test can be run either
by generating a data pattern from the locally attached DTE or by having
the modem generate a test pattern.
The following procedure describes how to run the local modem test
using a locally attached DTE to generate a data pattern.
Using the front panel test switch, place the modem in Analog
1.
Loopback mode.
Turn on the Request To Send line.
2.
Use the locally attached DTE to transmit the data pattern and check
3.
for data errors on the Receive Data line.
The following procedure describes how to run the local modem test
using the modem test pattern instead of a data pattern originated by the
local DTE.
Using the front panel test switch, place the modem in Self Test
1.
mode.
The TM indicator should turn ON. If the indicator turns OFF or
2.
flashes, errors are occurring.
Page 25
Page 25
Specifications
Line and Modem Test
The line and modem test verifies the local modem, the remote modem,
and the communications line between them. With this test, the local
modem loops back received data to the transmitter and transmits the
data to the remote modem. These characters can originate either from a
locally attached DTE or by having the modem generate a test pattern.
The following procedure describes how to run the line and modem test
using a locally attached DTE to generate a data pattern.
1.
Place the remote modem in Digital Loopback mode.
2.
Place the local modem in Data mode and transmit a data pattern.
Check for data errors on the Receive Data line
The following procedure describes how to run the line and modem test
using the modem test pattern instead of a data pattern originated by the
local DTE.
1.
Place the remote modem in Remote Test mode.
2.
Place the local modem in Remote Self Test mode. The TM LED
should turn ON and remain ON if the data is error free.
