To control a GVG 20-TEN
1
router via Harris control panels or automation software,
use the LXYTOGVG20 in conjunction with the GVG router. In this application, the
P12×1-SP will convert from X-Y to GVG protocol.
The LXYTOGVG20 supports all functionality of the Grass Valley/Tektronix 20-TEN
protocol. As the Harris protocol includes several features which are not supported
by Grass Valley, the LXYTOGVG20 adds those features to the control operation of
the 20-TEN. Standard protocol features are listed in
Table 4-8 . Additional protocol
features are listed in Table 4-9 .
