 Testing the refresh rates of LCD displays by using the motion patterns

2

850 - Getting Started

2 Getting Started

We recommend that you:

 Unpack the equipment carefully and save the original box and packaging

materials for possible future shipment

 Review the contents of this user manual

Use Kramer high performance, high resolution cables

Go to http://www.kramerelectronics.com/support/product_downloads.asp
to check for up-to-date user manuals, application programs, and to
check if firmware upgrades are available (where appropriate).

2.1 Achieving the Best Performance

To achieve the best performance:

 Use only good quality connection cables (we recommend Kramer high-

performance, high-resolution cables) to avoid interference, deterioration in
signal quality due to poor matching, and elevated noise levels (often
associated with low quality cables)

 Do not secure the cables in tight bundles or roll the slack into tight coils
 Avoid interference from neighboring electrical appliances that may adversely

influence signal quality

 Position your Kramer 850 DisplayPort Pattern Generator away from

moisture, excessive sunlight and dust

This equipment is to be used only inside a building. It may only be
connected to other equipment that is installed inside a building.

2.2 Safety Instructions

Caution:

There are no operator serviceable parts inside the unit

Warning:

Use only the Kramer Electronics input power wall
adapter that is provided with the unit

Warning:

Disconnect the power and unplug the unit from the wall
before installing

2.3 Recycling Kramer Products

The Waste Electrical and Electronic Equipment (WEEE) Directive 2002/96/EC

aims to reduce the amount of WEEE sent for disposal to landfill or
incineration by requiring it to be collected and recycled. To comply with the
WEEE Directive, Kramer Electronics has made arrangements with the
European Advanced Recycling Network (EARN) and will cover any costs of
treatment, recycling and recovery of waste Kramer Electronics branded

equipment on arrival at the EARN facility. For details of Kramer’s recycling

arrangements in your particular country go to our recycling pages at

Always switch off the power to any device before connecting it to your

850. After connecting your 850, connect its power and then switch on
the power to the device.

To connect the 850 as illustrated in the example in Figure 3:

1. Connect the DP OUT connector to a DisplayPort acceptor (for example, a
flat panel LCD display).

2. Optional—connect a PC to control the 850 via the RS-232 or USB port.

3. Connect the power adapter to the 5V DC socket and to the mains electricity.

8 Serial Protocol

The 850 can be controlled via the serial port using the commands described in this
section.

8.1 Command Format

Commands must be in the following format:

0xEB, address, command, length of data, data 1,…, data n, checksum

where the following table describes the command components.

Command
Component

Description

0xEB

Fixed command start byte

address

Device address. This is always 0x90 for the 850

command

Command to be sent (see Section 8.3)

length of data

How many bytes sent/received (from data 1 to data n)

data 1, data n

One or more command variables within the range 0x01 to 0xFA and excluding 0xEB

checksum

Optional—Checks whether the sending/receiving frame is valid.
Check sum = Address + Command + Data length + Data 1+…+Data n
For example, EBH, 90H, 01H, 01H, F3H, 85H
Check sum = 90H + 01H + 01H + F3H = 185H
Note: The checksum gets the low 8 bits, for example, if the check sum = EBH, then check sum =
14H

8.2 Device Response

The device responds as follows:

0xEB, 0x90, command, 0x01, answer, check sum

where answer is one of the values described in the following table.

Command
Component

Description

0xF1

Either:

–the device received the wrong address and returns no response
–the device gets information about Errors and Alarms

0xF2

The data is out of range. The command is not executed

0xF3

The device is currently controlled by the buttons. The command is not executed

0xF7

The data length is incorrect. The command is not executed

0xFC

The data is out of range. The command is not executed

24

850 - Serial Protocol

8.3 Commands

The commands listed below are supported by the 850.

8.3.9 Set Detailed Timing for User-defined Resolution

Command

Send/Receive

Data

0xEA

data18L_4bits, checksum

0xEB, address, 0xEA, 0x01, 0xFA, checksum

1. [block index]: From 0 to 7
Note: 7 is the preferred timing of the monitor, so it is
preferable to use 0 to 6

2. [perform immediately]: 1 = switch to the user-defined
resolution immediately, 0 = save the user-defined
resolution but do not switch

3. “H_”: high bits

4. “L_”: low bits

5. “data nH_4bits” and “data nL_4bits”: As, 0xfa apart to

0x0f and 0x0a

6. The 18 data are the detailed timing of the EDID.
