1.0 REGULATORY NOTICES

NOTE: This equipment has been tested and found to comply with the limits of

a Class B digital device, pursuant to part 15 of the FCC rules. These limits are

designed to provide reasonable protection against harmful interference in a

residential installation. This equipment generates, uses, and can radiate radio

frequency energy and, if not installed and used in accordance with the

instructions, may cause harmful interference to radio communications.

However there is no guarantee that the interference will not occur in a

particular installation. If this equipment does cause harmful interference to

radio or television reception, which can be determined by turning the

equipment off and on, the user is encouraged to try and correct the

interference by one or more of the following measures:

• Reorient or relocate the receiving antenna.

• Increase the separation between the equipment and the receiver.

• Connect the equipment into a different outlet than the one

which the receiver/driver is connected.

• Consult the dealer or an experienced radio/TV technician for help.

2.0 DESCRIPTION

The DLH6420 code distribution unit is a 16-channel RS-422 transmit

only (2-wire and ground) distributor. It was designed as an

accessory of the System DLH4200B, but can be used with any

system that uses RS-422 serial communications. The product will

primarily be used to install pan/tilt and dome receivers in a “star’’

configuration.

2.2 FEATURES

The DLH6420 has the following features:

• Two 8-position, RJ-45 connectors in parallel, providing an input

from a controller and an output for an additional daisy-chained

unit

• Sixteen 3-position screw terminal connectors used to output 16

RS-422 transmit only code lines

• Two-pin terminal connector (refer to figure 3) for an external 10

24 VAC/VDC power source

• Standard 120/230 VAC 50/60Hz line input (auto-ranging)

3.0 PRE-INSTALLATION INFORMATION

3.1 FRONT VIEW

Figure 1 illustrates the front view of the DLH6420 unit, which uses the

standard panel layout for the DLH4200B product line. A power LED indicator

(green) is located on the left and a data LED (red) is located on the right

side of the front panel of the unit. The power LED will light when power is

applied to the unit; the data LED will light when a transmission from the

controller is received by the DLH6420.

3.2 REAR VIEW

Figure 2 illustrates the rear (working side) of the DLH6420 unit. Note the

three-position terminal screw data output lines numbered 1 - 16, from left

to right. Next to that are the RJ-45 female IN/OUT communication ports and

the external, two-pin independent power input. Finally, the standard AC

power input cord connection is on the far right.

Figure 3 further details the mating plugs, pin-outs, and so on pictured in Figure 2.

Note that for externally supplied power sources, the DC supply hook-up can handle

forward or reverse hook-up of the input source. The internal bridge can handle either

polarity. There are, naturally, no polarity concerns with an externally supplied AC power

source.

4.0 INSTALLATION

Installation of the unit is straightforward. The unit is rack/wall

mountable and is only 8" deep (20.25 cm). In addition to the 16 lines

available for output with one unit, eight units may be daisy-chained

together. This will allow 128 receivers (that support 128 address

settings) to be connected on a single Sercom port. Figure 4 illustrates

two units daisy-chained providing 32 independent drive lines.

5.0 OPERATION

The DLH6420 unit works as a distribution repeater for expanding one RS-

422 communication port into 16 isolated and buffered RS-422 ports. The

primary use for the DLH6420 is to provide quick, easy, and proper data-

line distribution for serial type pan/tilt and dome receivers. In the case of

these isolated RS-422 drive lines, the remote devices may be located as

far as 4,000 feet (1,219 m) away from the controller, depending on the

physical parameters of the connection.The unit is ideal for use on larger

switching systems where it becomes desirable to “home-run” the RS-422

data lines for controlling pan/tilt or dome receivers.
