Getting Started

_____________________________________________________________________

Powering the Dark System Transmitter and Receiver

The transmitter (DSTR-5000) and receiver (DST-5000) are shipped without the batteries installed. The user should remove the rear cover on each unit and

install the battery packs before proceeding.

Using the external AC power supply: Make sure that the available AC

line voltage is 110-240V, 50/60 Hz. Connect the DC output plugs f rom each of the ada pter/cha rgers t o the DC recept acles on t he DST and DSTR units.

B) Powering the transmitter and receiver with internal batteries: In order

for the DST and DSTR t o operate from the internal batteries, a suff icient charge must exist on the batteries. The recommended time to fully charge the batteries is 5 hours. The power supply / battery charger included with the DST-5000 is different than the power supply / battery charger for the DSTR-5000. DO NOT interchange the chargers. The batteries will charge whether the units are switched On or Off. When the charg er for the transmit ter (DSTR) is c onnected to an AC so urce, the Charge LED will be illuminated Amber during a charging cycle and Green if charging is complete.

Warning: Only Use The Power Supply / Battery Charger Supplied by Holland Electronics with The Transmitter (DSTR-5000) and the Receiver (DST-5000). Do not interchange the charging units between the DST and DSTR units.

Use Of Any Other Chargers Will Void the Warranty and Can Cause Damage Or Injury.

Adjusting the transmitter carrier output levels

The transmitter carrier power levels should not normally need to be adjusted for the Dark System to operate properly. Ho wever, the levels can be checked when the uni t is used for the fir s t time or should the op erator experience trouble using th e equipment during normal operation.

The transmitter (DSTR-5000) output consists of five different frequency carriers. The power level of ea ch carrier can be adjusted separately with the potentiometers mounted on the top of the housing (near the output connector). The exact output level of each carrier is not extremely critical for nor mal operati on because the receiver input referenc e levels for each carr ier frequency are set to match the transmitter levels during a calibration process the user performs b y connecting the transmitter and receiver to gether pri or to making signal level measurements (See Section 2.1).

If the user prefers to know the ex act transmitt er output po wer levels then the transmitter can be directly connected to a spectrum analyzer or a power meter and each of the carrier levels set to a known value. Always reconnect the receiver and transmitter together and perform a calibration exercise to reset the receiver input reference levels (See Section 2.1) after adjusting any of the transmitter output level potentiometers.

Page 8

Operating Modes:

Once the meter power is turned on there are three different o perating modes and one set-up mode tha t can be selected. Pressing the MODE Key repeatedly will sequence the receiver through the different modes as described below in sections 2 - 5.

1. POWER ON

Press the Power Key to turn on the receiver. The LCD display will look similar to the following:

2. REC MODE

In this mode, the amount of inser tion loss between the transmitter and receiver connected to a cable under test is measured and displayed for fi ve different frequenci es. These insertion l oss values can also b e stored in memory and then recalled at a later time for review or downloaded to another device via the RS-232 port.

• The measurement level is displ ayed over a range of 20 bars, at 2 dB per bar. When all bars are illumina ted for a given frequency t hen there is less than 2db of measured signal level insertion loss betw een the tra nsmitter and receiver.

Page 9

2.1 Measuring Insertion Loss: The Insertion Loss or the Attenuation of the cable under test (CUT) can be measured as follows:

2.1.1 Connect the transm itter dir ectly to the i nput of the receiver. Use a high

quality splice or a jumper cable that is no more than 1 2 inches between transmitter and receiver for this step. NOTE: Normally the transmitter output levels do not require adjustment b efore perfo rming this step unles s the operat or is experiencing erratic op erati on or measurements

2.1.2 Press th e CAL Key to initiate a calibration operation. The receiver will store

the measured signal levels of each carrier and use them as reference levels. The LCD display will appear as shown below.

2.1.3 The display will t hen show all five bars fully illuminated across the screen

and –0db noted for each fr equency. If -0db is not displayed for each value then try adjusting the carrier level potentiometer on the transmitter for the frequency in question a nd repeat t he calibrat ion procedure.

2.1.4 Disconnect the transmitter fr om the receiver and connect the transmitter

to one side of the CUT and the receiver to the other side. The receiver will display the a ttenuation values of the CUT. The LCD should look similar to the following :

Page 10

2.1.5 To store the measured values, use the / keys to select a desired

memory station (1-50) on the disp lay. Then press the MR Key for 2 seconds to stor e the measurement data into the desi gnated station memory location.

The letter “M” will be displayed in the upper right corner of the screen to indicate stored values in the desig nated station memory location. Old data must be cleared from a statio n by pressing and holding the MC Key for 5 seconds before new measured values can be saved.

The stored data in all fifty memory locations can be cleared in a single operation by pressing both the MC Key and the STKey for 5 seconds.

3. CABLE ID MODE:

In this mode, the receiver can be used to id entify uni d entifed cables by attaching specially m arked terminators (Holland p/n PFTK) to one end of each cable. The meter can read the terminator resistance and display the specific ID of the terminator corresponding to the chart below:

3.1 Press the MODE key to select Cable ID mode. The LCD will display as shown
