The SXVR-M26C 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 SXVR-M26C 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 SXVR-M26C.
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.

Camera maintenance:
Very little maintenance is needed to keep the SXVR-M26C in excellent operating
order, however two problems, which are common to all CCD equipment, might show
up on occasion. These are dust and condensation.
