1. OVERVIEW
The X1200 series twelve input routing switchers provide a convenient, low cost way to route Standard and
High definition serial digital signals. The X1200S routers are used for 270, 360 & 540Mb/s standard
definition serial digital signals, while the X1200H routers are used for 1.5Gb/s HDTV serial digital signals.
The router is available in video only or video with AES configurations. The X1202S-AES and
X1202H-AES units come with 2 levels of AES audio routing for each of the two video busses. The
X1202S-AES4 and X1202H-AES4 units come with 4 levels of AES audio routing for each of the two video
busses. The X1201 routers have only one video bus and similar audio configurations. The AES output
busses can be used in an audio follow video mode, or can be broken away from their associated video
buss. Table 1-1 shows the model numbers of the basic routers and the capabilities of each.

Table 1-1: Basic Router Models and Features
**Some early versions of the X1202H-AES models were shipped with two audio breakout panels. On
these units, the AES audio router sections can also be configured as four 12 x 1 AES audio busses. (The
assignment of which mode the AES section of the router operates and which AES busses are associated
to the Video busses is programmable from the Setup menu.)
The router electronics is housed in a 1RU rack mount frame with breakout panels for the audio
connections. The standard router has built-in front panel controls, but can also be purchased with a rack
mount remote control panel that replaces the built-in control panel (RCP version). An additional remote
control panel (X1202S-REMOTE or X1202H-REMOTE) can also be ordered for any version. All units can
also be controlled by contact closures on the GPI control port or through the RS-232 serial remote control
port using industry standard switcher protocols.
The SoftSwitch versions (referred to as SS versions throughout this manual) of the router have the
following additional features. The Video 1 output has adjustable vertical timing with respect to the genlock
input, and line synchronizers on the video inputs can accommodate differences in timing up to
approximately +/- one half line for the V1 output. All the AES outputs will have a continuous AES carrier
locked to either the video genlock or DARS reference (when the DARS reference is used, Z bit alignment
of the AES outputs is also guaranteed). The audio outputs that follow the Video 1 buss use Evertz patent
pending SoftSwitch technology to eliminate audible pops when switches are performed. For the
SoftSwitch technology to function correctly, the audio sources must be synchronous with the chosen
