5. INSTALLATION
5.1 GENERAL
The DLTM4 module is the test data generator / receiver and measurement device used in the AL6300-LCD Data Link Test
Set. It also may be used in the AL4300-LCD series equipment in combination with Apogee Labs data multiplexing /
demultiplexing devices. The module is self-contained: transmitter, receiver, and measurement functions are combined
with a microprocessor that supports front panel and remote control operations. Signal input and output connections are
provided on the circuit board I/O panel. The module does not connect to the data paths on the chassis backplane. Only
DC power is drawn and front panel communication occurs with the chassis. When used in the AL6300-LCD chassis, front
panel LCD status indicators are connected to the module. These indicators are user-configurable to illuminate for
conditions that benefit the user. All operating firmware is contained on the module. Therefore, installation of a DLTM4 in
the field is accomplished simply by plugging it into an Apogee Labs LCD chassis.
5.2 MODULE PLACEMENT CONSIDERATIONS
The DLTM4 plug-in module requires three card slots and can be placed in any slot of an AL6300-LCD chassis .When
placing the DLTM4 in an AL4300-LCD chassis, it also may be placed anywhere within the chassis. When placing the
DLTM4 in a chassis that also contains multiplexing equipment, in the interest of operational efficiency, it is best to place
this module in the card slot at the far right side of the multiplexing cards facing the rear of the chassis.
Module position has an effect on front panel and remote control operations. When the PAGE/NEXT/PREV keys are
depressed, the next or previous card slot is activated for front panel operations. Remote control of a module is governed
by the slot in which the module resides. The Slot number of each installed module is determined by the slot number along
the top that is white.
5.2.1 SYNC STATUS INDICATION (AL6300-LCD CHASSIS SYNC DISPLAY)
Located on the top of the front panel LCD display of an AL6300-LCD or AL4300-LCD chassis are a row of status
indicators. These indicators are user configurable and can be set to turn green or red depending on what the user set as
fault conditions. Any status field can be monitored and a condition can be set to change the status indicator from one color
to another.
5.3 CONNECTION & PHYSICAL CONFIGURATION
The DLTM4 module outputs and inputs serial test data with an associated coherent clock. The signaling to this module
may be either TTL or RS-422. The TTL serial input connectors are BNC type with shield connected to chassis and digital
ground. RS-422 signals are to be found on the Triaxial connectors.
An external, user supplied, TTL level bit-clock may be used in place of the internally generated clock. This is called system
timing (ST). This signal is applied to a BNC connector. It is recommended that good quality coaxial cables be used for all
signal connections. Figure 2 illustrates the connector panel and side view of the module. Table 1 provides the termination
configuration for the DLTM4. Table 2 provides definitions for each connector and an associated reference line drawing of
the I/O panel detailing the location and designation of the connectors.
