HOW DO I GET STARTED?
The fastest way to get started is to take your time and do everything right the first time. Taking 15
minutes to read the manual may save you a few hours later. You don't even have to read the whole
manual. If a section doesn't apply to you, you don't have to spend your time reading it.

OPTIONAL ACCESSORIES
The following accessories, which are available from Kramer, can enhance implementation of your
distributor. For information regarding cables and additional accessories, contact your Kramer dealer.
SD-7308 – for switching between SDI sources: The machine is a multi-standard, adjustment-free 8x1
switcher for SDI (serial digital) video signals. It accepts up to eight SDI inputs, provides necessary
buffering and reclocking, and routes the selected source to four identical SDI outputs using BNC
connectors. It provides automatic equalization for losses typical with long runs of 75-ohm co-axial cable.
Depending on the cable and video standard, cable length of several hundred meters is possible. Standard
recognition is automatic and the machine switches during the vertical interval according to the SMPTE RP-
168 standard. A rear-panel output level control is provided to optimize signal level. The input select
function of the SD-7308 can be controlled by front panel buttons and by RS-232 commands transmitted by
a touch-screen control system, personal computer, or other control system. When no signal exists on a
selected input, the LED in the appropriate button flashes. The SD-7308 automatically recognizes the word
length for both 10-bit and 8-bit video.
SD-7388 - an adjustment-free, 8x8 matrix switcher for SDI (serial digital) video signals. It is a true
matrix allowing any input to be routed to any or all outputs simultaneously. It provides automatic
equalization for losses on a 75-ohm co-axial cable, and reclocks each output to provide 8 low-jitter serial
digital outputs. Video standard recognition is automatic, and the SD-7388 switches during the vertical
interval. The SD-7388 accepts either analog or serial video as the external source for its vertical trigger, and
any output can be assigned as the sync source. The SD-7388 can be controlled by front panel buttons, RS-
232 and RS-485. It is fully compatible with both 10-bit and 8-bit video, automatically recognizing word
length.
SD-7401 - a multi-standard, adjustment-free digital to analog converter designed to accept an SDI
(4:4:2 serial digital video) input, and provide analog outputs in four common signal formats. The SDI input
is equalized and reclocked, and converted to composite video, S-video (Y/C) and component video (RGsB
or Y, R-Y, B-Y) outputs simultaneously. The SD-7401 also has an internal 75% color bar generator, whose
timing is based on the SDI input. The SD-7401 encodes 525 line signals to NTSC-M and 625 lines to PAL-
B. Versions designed for other standards such as SECAM, PAL-M, and NTSC 4.43 may be available by
special request. When encoding NTSC, the unit may be programmed with or without a 7.5 IRE setup
(pedestal).
