4 The CoCo Controller-48V
The CoCo Controller-48V panel is designed to control the CoCo104 Colour Corrector and
Legaliser using a RS422 serial link. The controller has dedicated buttons for each of the
eight sources and eight destinations together with a TAKE button and Salvo SAVE and
RECALL buttons.

4.1 Installing the CoCo Controller-48V
The CoCo104 has a number of external control lines that can be configured for GPI or
RS485 control. These control lines MUST be configured for RS485 to enable CoCo
Controller-48V communication as explained in section 6.5. It is NOT possible to retain
GPI control when the controller panel is enabled. However, the CoCo Controller-48V
panel has its own GPI control built in, which is explained later in this chapter.
The panel communicates with Crystal Vision frames via a serial communication link
using the 422 BUS port at the rear of the panel. Standard UTP patch cables may be used
with an appropriate adapter for the Crystal Vision frame remote connector.

The RJ45 422 BUS port is next to the GPI I/O connector. Other RJ45 connectors and the
four-way DIP switch are NOT used.
Each card slot in a frame has its control lines brought out to different 26 way ‘D’ type
frame remote connectors on the rear of the frame. The following tables show which
remote connectors to use for different frames and frame slots:
