Key Label Description
9
VGA (OUTPUTS) Female, 15-pin, “D” connector that provides the analog RGB signals and the
vertical and horizontal sync signals necessary to operate a standard SVGA
monitor at 800 x 600 resolution.*
10
COM (CONTROL) Female, 9-pin, “D” connector that allows RS-232/RS-422 communication
with the RCU-200 or the PC. The communication parameters are no parity,
8 data bits, and baud rate selectable from the SETUP menu (as shown in
Table 3-5 on page 3-18).*
11
GPI/TALLY (CONTROL) Male, 9-pin, “D” connector for remote selection of the video input by
accepting momentary contact closures to the Channel Select Return line. It
also accepts a continuous contact closure to the ON AIR Return line to
indicate ON AIR status by causing the on-screen ON AIR indicator area to
turn red. The Error Summary signal, the only output of this connector, is the
normally open contact of a relay that makes contact with Error Summary
Return for approximately one second, if the selected input is from a serial
digital source, and an EDH or Data Error occurs.*
12
KEYBOARD 6-pin, mini, DIN connector for an IBM PS2-style keyboard connector to allow
user remote control of the VTM-200.*
13
AES/EBU IN C1 BNC connector for an AES/EBU serial digital stream carrying a stereo pair of
audio channels. The 18 most significant bits of each channel are converted
to analog form. If selected for display and output via the AUDIO FOLLOW
Menu Items, the analog audio derived from the selected AES/EBU input will
appear at the AUDIO OUT connector with an attenuation determined by the
AES/EBU AUDIO LEVEL Menu Item. Its levels and phase difference will be
displayed in the on-screen audio display.
14
AES/EBU IN C2 Same as 13.
15
AES/EBU IN D1 Same as 13.
16
AES/EBU IN D2 Same as 13.
17
AUDIO IN A1, A2 Twenty screw-terminal connectors for eight analog audio signals (four stereo
pairs). Each signal input accepts a balanced input (H, L) and a shielded
ground (G). If selected for display and output via the AUDIO FOLLOW
Menu Items, the analog audio will appear at the AUDIO OUT connector with
an attenuation determined by the ANALOG AUDIO LEVEL Menu Item. Its
levels and phase difference will be displayed in the on-screen audio display.
18
AUDIO IN B1, B2 Same as 17.
19
AUDIO OUT 1, AUDIO
OUT 2
Ten screw-terminal connectors that output the two analog audio stereo pairs
selected by the AUDIO FOLLOW Menu Items. The gain of the audio is
determined by the AES/EBU AUDIO LEVEL and ANALOG AUDIO LEVEL
Menu Items. Its levels and phase difference will be displayed in the on-screen
audio display.*
20
INPUT POWER Three-prong power connector that accepts nominal 115V AC to 230V AC, 50
to 60 Hz single phase to power the VTM-200. The VTM-200 will auto detect
the supply voltage, and adjust itself to it. The connector incorporates an
inline 5 x 20 mm 2.0 A time-lag fuse.
21
FAN Seven-cfm fan operates whenever power is applied to the VTM-200, and
functions to cool the VTM-200. It exhausts air out of the unit.
