// Setting the jump speed and mark speed:

set_mark_speed( 250.0 );
// In RTC4 Compatibility Mode the RTC6 board multiplies the speed values by 16.
// Jump speed = 1000.0 bits/ms.
// Marking speed = 250.0 bits/ms.

// In RTC4 Compatibility Mode the timing parameters are specified in units of 1/8 µs.
// The RTC6 board multiplies the specified values by 8 to convert them to
// integer-multiple of 1/64 µs. Laser HalfPeriod = 100 µs.
// Laser pulse length = 50 µs.
// Setting the Laser Delays, see Chapter 7.2.1 ”Laser Delays”, page 145.

// LaserOn Delay = 100 µs.
// LaserOff Delay = 100 µs.
