Switch-on Characteristics
Once the supply voltage has been applied, the antenna requires 10 s until it reacts to
data input, or outputs data protocols. During these 10 s, a software download may be
started (also refer to section 4.2.7 on page 26).

Serial (RS 422 / RS 232)
The serial output may be configured in several ways. The transmission rate is adjust-
able between 9600 and 19200 Baud, the output protocol may be chosen as “transpar-
ent“ or “3964R“. Apart from that, the content of the telegrams is configurable, as the
user may choose from a list of parameters.
Serial commands are used for activating a system monitor. The crossing of the anten-
na´s center axis in direction of travel, is shown by the digital positioning output. Its
transmission time is adjustable in blocks of milliseconds. In addition, it may be re-
duced to one impulse per crossing.

List of system data to be output
A telegram consists of max. 15 bytes. The minimum update rate at 9600 Baud is then
calculated as follows

Formula: minimum update rate
As the transmission is binary, it is possible - when using the 3964R procedure - that
further (DLE) characters are added by this procedure. All multiple-byte variables are
output either with the highest byte or the lowest byte first (adjustable)!
