The SXV-H9C accessory ports
The SXV-H9C is provided with two ports for use with accessories. The Autoguider
output port is a 6 way RJ11 socket, which is compatible with the standard autoguider
input of most telescope mounts. It provides 4 active-low opto-isolator outputs and a
common return line, capable of sinking a minimum of 5mA per output. This socket
may be used for telescope control if the SXV-H9C is employed as an autoguider, but
is primarily intended to be the control output for the optional add-on autoguider
camera head, available for use with the SXV-H9C.
The high density parallel port socket provides both control and power for the add-on
autoguider, but also includes a pair of serial ports for use with other devices.
