Note Refer to the latest version of the Routing Products Protocols Manual for
information about the Terminal/Computer Interface (T/CI) Protocol used to
control Acappella systems. This manual is available for download on the
Grass Valley web site (see
page 4 ).
Ethernet Cabling
The Acappella frame uses Ethernet to communicate. Use standard pin-to-
pin (patch) Category 5e cables if you are using switches between the
routers, panels, and PC. It is also possible to use a crossover cable to
connect an Acappella Router directly to either a Remote Panel or a PC; this
option is only practical in very small systems.
Figure 35 shows a Closed
Network system with an Acappella router, a Remote Panel, and a PC con-
nected to a switch.
