3.1 CONFIGURATION SWITCHES (MODEL 2042MC-MT)
The Model 2042MC-MT has miniature DIP switches that you may
use to configure the units. Each Model 2042MC-MT is factory config-
ured as DCE on the RS-530 end, and DTE on the HSSI end.
Therefore, the RS-530 end “wants” to plug directly into a DTE device.
Conversely, the HSSI end of the converter “wants” to plug directly into
DCE.
Please use this section to configure the internal DIP switches so
that the unit will work properly in your application. Figure 3 shows the
position of the DIP switches on the top side of the PC board.
Figure 4 shows the orientation of the switches on DIP Switches S1
through S4 with respect to ON/OFF positions. The default settings for
DIP Switch S1 are shown in the table 1 on page 6. Detailed descrip-
tions of each switch follow the table.

Switches S1 and S2: Clock Source
The setting for Switches S1 and S2 determines the source of the
HSSI Terminal Timing (TT) for the 2042MC-MT. With Switch S1 On
and S2 Off, the Model 2042MC-MT derives the HSSI Terminal Timing
from the ST signal provided by the HSSI DCE. With Switch S1 Off,
and S2 On, the RS-530 DTE provides TT to the HSSI DCE.

Switches S3 and S4: Synchronization Method
Switches S3 and S4 allow the Model 2042MC-MT to compensate
for timing delays when transmitting HSSI data at high speeds (greater
than 2.5 Mbps). At high bit rates, set Switch S3 On and Switch S4 Off.
In this setting, the RS-530 data will be synchronized to the SD timing
signal before conversion to HSSI. At lower bit rates (less than 2.5
Mbps), set Switch S3 Off and S4 On. In this setting, the RS-530 data
bypasses the synchronization circuit and is passed straight through to
the HSSI DCE.

ured as DTE on the RS-530 end, and DCE on the HSSI end.
Therefore, the RS-530 end “wants” to plug directly into a DCE device.
Conversely, the HSSI end of the converter “wants” to plug directly into
DTE.

Switches S1 and S2: Gapped Clock
Switches S1 and S2 allow the Model 2042MT-MC to generate a
HSSI gapped clock. Gapped clocking is a method of flow control in
which data flow is interrupted by an idle (gapped) clock signal. In this
mode, the Model 2042MT-MC will gap the ST clock to the HSSI DTE
whenever the RS-530 CTS signal is de-asserted. In the ‘No Gapped
Clock’ setting, the RS-530 clock passes through with only a level
change.

Switches S3 and S4: Synchronization Method
Switches S3 and S4 allow the Model 2042MT-MC to compensate
for timing delays when transmitting HSSI data at high speeds (greater
than 2.5 Mbps). At high bit rates, set Switch S3 On and Switch S4 Off.
In this setting, the HSSI SD signal will be synchronized to the SD tim-
ing signal before conversion to RS-530. At lower bit rates (less than
2.5 Mbps), set Switch S3 Off and S4 On. In this setting, the RS-530
data bypasses the synchronization circuit and is passed straight
through to the HSSI DTE.

4.0 INSTALLATION
The Model 2042 is designed to connect RS-530 devices to
devices which employ the HSSI interface standard. This section
describes how to install the units.
4.1 2042MC-MT CONNECTION
The Model 2042MC-MT is designed to connect an RS-530 DTE
device to an HSSI DCE device. In this application, the DB-25 (RS-
530) and HD-50 (HSSI) male connectors of the Model 2042MC-MT
may connect directly to their respective equipment ports, or they may
connect via a short “straight-through” cable (See Appendix C for
Interface Pin Assignments). Figure 7 below illustrates the proper con-
nection of the Model 2042MC-MT.
4.2 2042MT-MC CONNECTION
The Model 2042MT-MC is designed to connect an RS-530 DCE
device to an HSSI DTE device. In this application, the DB-25 (RS-530)
and HD-50 (HSSI) male connectors of the Model 2042MT-MC may
connect directly to their respective equipment ports, or they may con-
nect via a short “straight-through” cable (See Appendix C for Interface
Pin Assignments). Figure 8 below illustrates the proper connection of
the Model 2042MT-MC.

4.3 AC POWER CONNECTION
The Model 2042 uses a 5VDC, 2A universal input, power supply
that is equipped with a male IEC-320 power entry connector and sup-
ports a voltage range of 100-240VAC. This transformer connects to
the Model 2042 by means of a cannon jack on the rear panel. There
are a variety of domestic and international power cords available for
the power entry (See Appendix B). The Model 2042 is powered-up as
soon as it is plugged into an AC outlet–there is no power switch.
4.4 DC POWER CONNECTION
The 36-60 VDC DC to DC adapter is supplied with the DC version
of the Model 2042. The black and red leads plug into a DC source
(nominal 48VDC) and the barrel power connector plugs into the barrel
power supply jack on the 2042.

5.0 OPERATION
Once you have configured the Model 2042 properly (see Section
3.0) and have correctly connected DTE, DCE and power (see Section
4.0), you are ready to operate the unit. This section describes the LED
status monitors and loopback test modes.
5.1 BACK PANEL LED STATUS MONITORS
The Model 2042 features two LEDs that are located on the back
panel. Figure 9 below shows the positions of the LEDs. Following
Figure 9 is a description of each LED.
Status Glows green to indicate that both DTR (from the DTE
device) and DSR (from the DCE device) are active.
This LED will not be illuminated whenever one of the
two signals are inactive.
Test Mode Glows green to indicate that either one or both of the
test modes are active (See Section 5.2 for a description
of the test modes).
5.2 TEST MODES
The Model 2042 supports two loopback modes that may be used
to evaluate the condition of the communication links. These modes,
(Local Loopback (LL) and Remote Loopback (RL), are always initiated
by the signals on the DTE device (See Figure 10). This section
describes both loopback modes.

NOTE: HSSI supports a third loopback mode: Local Digital
Loopback (LDL). However, RS-530 does not support this mode.
In order to use LDL, the RS-530 device must be programmed to
respond according the the HSSI specification for LDL (See
TIA/EIA-613, Section 6.2.1 Local Digital Loopback (Loop A).

5.2.2 Remote Digital Loopback (RL)
The Remote Loopback (RL) test checks the performance of the
link between the DTE device and the DCE as well as the link between
the local and remote DCE devices. Any characters sent from the DTE
in this test mode will be sent to the local DCE, which will send the data
to the remote DCE. The remote DCE should return the data back
through the entire communication link and finally, to the DTE. To per-
form a RL test, follow these steps:
A. Activate RL from the DTE device. This may be done either by
raising pin N on the RS-530 interface (if the RS-530 device is
DTE), or by activating Local Loopback from the HSSI interface (if
the HSSI device is the DTE). The “test” LED should be lit.
B. Perform a BER (bit error rate) test from the DTE.
C. If the BER test equipment indicates a fault, and the Local
Loopback test was successful, you may have a problem with the
cable between the DCE devices.
NOTE: The Model 2042 simply converts and passes the data
through the communication link. The DCEs must be configured
to perform to the appropriate loopback diagnostic.
13
5.2.1 Local Loopback (LL)
The Local Loopback (LL) test checks the performance of the link
between the DTE device and the DCE. Any data sent to the Model
2042 from the DTE in this test mode will be sent to the local DCE and
will then be echoed (returned) back to the DTE (the Model 2042 simply
converts and passes the data to the the local DCE, which must per-
form the loopback). To perform a LL test, follow these steps:
A. Verify that the data terminal equipment is operating properly
and can be used for a test. If a fault is indicated, call a technician
or replace the unit.
B. Activate LL from the DTE device. This may be done either by
raising pin L (if the RS-530 device is DTE), or by activating Local
Loopback from the HSSI Interface (if the HSSI device is the DTE).
The “test” LED should be lit.
C. Perform a BER (bit error rate) test from the DTE. If the test
indicates no fault, deactivate LL and proceed as normal.
