Chapter 1: Remote commands for Antenna Masts and Stands
General information
- All outputs through the Interface-Bus are five characters long, followed by Line Feed
(0AH). Missing positions are filled with blanks (20H).
- All values are transferred in CM.
- Negative values are not allowed.
- The commands, values and units must be transferred in capital letters and separated
by blanks.
- No more than 32 characters may be sent in one transmission.
- The Line Feed or the EOI can be used as an end character (CR will be ignored).
Registers
The Bus interface of the control device has several registers available. By transmitting the
register name, the register is made the current register. If the device is addressed as
TALKER, it outputs the contents of the register set.
If a value has been loaded previously with LD, it is accepted into the next following register.
Input Registers
These registers can be assigned a value with the LD command. They can be readout when
the register name is received and the control unit is then addressed as TALKER.
