Innovator CHV400BTD ATSC Transmitter Unpacking and Installation
Technical Manual, Rev. 0 12
The Innovator CXB Series systems are 17” (43.2cm) wide standard rack mountable trays.
They are supplied with side mounted Tray Slides for ease of installation and removal. The
CHV200 system is 3 RU, 5.25” (13.3cm), high. The CHV400 and CHV500 systems are 9 RU,
15.75” (40cm) high, which is 3 RU, 5.25” (13.3cm) for the driver and 6 RU, 10.5” (26.7cm)
for the 400 watt Innovator CHVB Series amplifier tray. The CHV1000 systems are 15 RU,
26.25” (66.7cm) high, which is 3 RU, 5.25” (13.3cm) for the driver and 12 RU, 21” (53.4cm)
for the two Innovator CHVB Series amplifier trays. The CHV1500 systems are 15 RU, 26.25”
(66.7cm) high, which is 3 RU, 5.25” (13.3cm) for the driver and 12 RU, 21” (53.4cm) for the
two Innovator CHVB Series amplifier trays. The CHV2000 systems are 21 RU, 36.75”
(93.3cm) high, which is 3 RU, 5.25” (13.3cm) for the driver and 18 RU, 31.5” (80cm) for the
three Innovator CHVB Series amplifier trays. The CHV3000 systems are 27 RU, 47.25”
(120cm) high, which is 3 RU, 5.25” (13.3cm) for the driver and 24 RU, 42” (106.7cm) for the
four Innovator CHVB Series amplifier trays. In all the systems just described, if the Axciter
is also part of the system, another 3 RU, 5.25” (13.3cm) must be added to the rack space
for the Axciter tray.
Also needed for FCC compliance operation is an ATSC filter on the broadcast channel that
connects to the output of the CHV200 thru CHV3000 systems. Space must be provided for
the ATSC filter, and in some systems, for the circulator, splitter, combiner, reject load, and
low pass filter, whose dimensions will vary depending on manufacturer and channel. Refer
to the vendor supplied information included with your ATSC filter and low pass filter for
specific dimensions. Make sure that the space provided for the CX Series equipment is
sufficient and includes the circulator, splitters, combiners, reject load and external filters.
Check that any additional equipment, which is included in the system that extends above or
to the side of the mounting rack, has sufficient clearance space. Refer to the custom
racking plan for the system, if prepared, for detailed information.
Tray Slide Installation
If the system is pre-mounted in a cabinet skip this section. Locate the tray slides included in
the installation material for your system. See Figure 2 and the manufacturers instructions,
included with the tray slides, for the cabinet mounting instructions of the tray slides. Install
the left tray slide into the left side of the cabinet (as viewed from the rear). Allow 3 RU, 5.25”
(13.3cm) of space between the trays for a CHV200B system. In high power systems, allow a
space of 3 RU, 5.25” (13.3cm) for the driver and 6 RU, 10.5” (26.7cm) for each of the
Innovator CHVB Series amplifier trays in higher power systems. Space must also be
provided for the splitter, combiner, ATSC filter and low pass filter, if present, whose
dimensions will vary depending on the manufacturer and the output channel. Secure the
left tray slide by connecting it to the front and rear mounting bars using No. 10 screws and
the bar nuts that have been provided. Install the tray slide on the right side of the cabinet
(as viewed from the rear) making sure that it is aligned with the tray slide on the left side.
Secure the slide by connecting it to the front and rear mounting bars using No. 10 screws and
the bar nuts that have been provided. Repeat this process for any other trays if purchased.
With both slides in place, slide the tray or trays into the cabinet.
