3 Overview
The high quality Kramer DigiTOOLS 7508 CV / YC to SDI Converter is a
multi-standard converter of analog video (composite and s-Video) to
SMPTE-259M serial digital video (SDI). Many professional video units on
the market today, such as Betacam decks and DVD players have high quality
analog outputs, and the 7508 is ideal for preserving the quality, and
minimizing the artifacts, when converting to the digital domain.

Your 7508 CV / YC to SDI Converter
In particular, the 7508:
• Converts the SDI on 2 buffered and reclocked SDI outputs
• Automatically detects the input standard (50/60Hz), generating the
appropriate output
• Uses true 10-bit digitizing, making it ideal for the most demanding
applications
• Has an RS-232 port and can be controlled via a user-friendly
Windows®-based program that can modify video parameters such as contrast,
saturation and hue, which may be stored in non-volatile mem ory
To achieve the best performance:
• Connect only good quality connection cables, thus avoiding interference,
deterioration in signal quality due to poor matching, and elevated noise levels
(often associated with low quality cables)
• Avoid interference from neighboring electrical appliances that may
adversely influence signal quality and position your Kramer 7508 away from
moisture, exc essive sunlight and dust

5 Using Your 7508 CV / YC to SDI Converter
You can use your 7508 CV / YC to SDI Con verter to convert professional
quality composite video or s-Video (as the example in Fig ure 2 illustrates) to
one or two SDI video outputs.
To convert composite video or s-Video to up to 2 SDI video outputs, do the
following
1. Connect a composite video source (for example, a VCR) to the CV BNC
2. Connect an s-Video source (for example, a camera) to the Y/C 4p INPUT
3. Connect both SDI outputs to SDI acceptors as follows (when only one

an SDI monitor)
• Connect the SDI OUT 2 BNC connector to the second SDI acceptor (for
example, an SDI monitor)

SDI output is required, use either of the SDI outputs of the 7508, and
leave the other SDI output unconnected):
4. Set the dipswitches, as section 5.2 describes
5. Connect the 12V DC power adapter to the power socket and connect the
adapter to the mains electricity.
The composite video

5.1 Connecting a PC
To connect a PC to the 7508 unit, using the Null-modem adapter provided
with the machine (recommended):
• Connect the RS-232 DB9 rear panel port on the 7508 unit to the
Null-modem adapter and connect the Null-modem adapter with a 9 wire flat
cable to the RS-232 DB9 port on your PC
To connect a PC to the 7508 unit, without using a Null-modem adapter:
• Connect the RS-232 DB9 port on your PC to the RS-232 DB9 rear panel
port on the 7508 unit, as Figure 3 illustrates
(depending on whether the PC has
a 9-pin or 25-pin connector)

Communication Protoc ol
DESCRIPTION OF INSTRUCTIONS
INSTRUCTION 0 – RESET
DATA=0: initialize the machine.
When the machine is initialized, it will send the RESET code (D ATA = 0). If the machine receives this code, it will reset to
its “power-up” state.
DATA=1: configure the machine to its factory default state.
When the machine receives this code, all programmable parameters will be reset to their factory-default values.
EXTENDED DATA - set as 0.
INSTRUCTION 1 – READ INPUT STANDARD
For sending to machine, set DATA = EXTENDED DATA = 0.
When replying:- DATA = INPUT STANDARD; EXTENDED DATA = 0. The PC sends this instruction to the machine. The
machine replies by sending back the INPUT STANDARD, defined as per the table below:
Table 6: Input Standard
STANDARD E2 E1 E0
NTSC (J, M) 0 0 0
PAL (B, G, H, I, N) 0 0 1
PAL-M 0 1 0
Combination PAL-N 0 1 1
INSTRUCTION 3 – READ BACK-PANEL DIP-SWITCH 1 (VIDEO FORMAT) (read format)
When sending to machine:- DATA, EXTENDED DATA - set as 0.
When replying:- EXTENDED DATA = back-panel DIP switch 1 (0 =CV, 1=Y/C).; DAT A = 0. The PC sends t his instruction
to the machine. The machine replies by sending back a value relating to the current video format.
INSTRUCTION 10 – WRITE EEPROM DATA
DATA = EEPROM sub-address; EXTENDED DATA = data to be written to this sub-address. The PC sends data directly to
the EEPROM. The EEPROM stores this new value, and replies by sendin g the same data back to the PC. CAUTION – this
function was designated for development and testing purposes. Improper use of this function may cause erratic behaviour of
the machine.
INSTRUCTION 11 – READ EEPROM DATA
For sending to machine, DATA = EEPROM sub-address.
When replying:- DATA = EEPROM sub-address; EXTENDED DATA = requested data.
The PC sends this instruction to the machine. The machine replies by sending back the data of this sub-address.
INSTRUCTION 12 – WRITE I²C
DATA = I²C sub-address; EXTENDED DATA = data to be written to this sub-address.
The PC sends I²C data (to the I²C address which was last accessed via INSTRUCTION 13). The machine replies b y sendin g
the same data back to the PC.
CAUTION – this function was designated for development and testing purposes. Improper use of this function may cause
erratic behavior of the machine.
INSTRUCTION 13 – READ I²C
For sending to machine, DATA = I²C address; EXTENDED DATA = sub-address.
When replying:- DATA = sub-address; EXTENDED DATA = data read.
The PC sends this instruction to the machine. The machine replies by sending back the data of this address and sub-address.
INSTRUCTION 16 – ERROR
If the machine receives an invalid instruction, it replies by sending this error code.
INSTRUCTION 57 – ENABLE “POWER-DOWN SAVE”
DATA = 0 disables power-down saving; DATA = 1 enables saving. EXTENDED DATA - set to 0.
The PC sends this instruction to the machine. The power-down option is enabled or disabled according to the value of DATA.
If the power-down option is enabled, then the machine will “re member” its state before being turned off, and revert to thi s
state when turned on again.
Note that whenever the machine is turned on, the power-down save option is enabled.
INSTRUCTION 61 – IDENTIFY MACHINE
For sending, DATA = 1 to request machine name; DATA = 3 to request software version number. EXTENDED DATA - set
to 0.
The PC sends this instruction to the machine. The machine relies as follows:
if the machine name is requested, the machine replies with DATA = 75 (hex), and EXTENDED DATA = 01 (hex).
if the software version is requested, the machine replies with DATA as the version nu mber before the decimal point, and
EXTENDED DATA is the value following the decimal point. For example, for version 3.4, the machine replies with DATA =
03 (hex), and EXTENDED DATA = 04 (hex).
