Components and Operation – Chapter 5
5.2.2.1.3 Programming of Transponders (serial)
The programming procedure is started by sending 0050
16
in command byte 2. Put
the code to be programmed into the 3 parameter bytes.
The one-time programming process lasts 100 to a maximum of 200 ms. Afterwards
the new code can be read out immediately.
In case the programming process wasn‘t successful repeat the programming proce
-
dure. A new programming can only be initiated if the command 3 CLR_PROG has
been sent first.
5.2.2.1.4 System Monitor
In monitor mode the system is configurable via a menu. Please refer to section 6.3
„System Monitor“ on page 34.
The monitor mode should not be used during normal operation (e.g. from a PLC)
since the output is no longer according to the transparent or 3964R protocol but
switches to a protocol suitable for the display on a VT52 terminal and only serves for
the manual configuration of parameters.
5.2.2.2 Positioning Pulse (all Variants)
The digital positioning output indicates the crossing of the center line of the antenna
in direction of travel (X-direction). Its duration is adjustable within a millisecond pat
-
tern. In addition it can be limited to one pulse per crossing.
5.2.2.3 CAN (Version HG G-71910ZC)
If the antenna is the last device on the CAN bus you need to activate a terminating
resistor. You can find it on the board of the antenna, see section 6.3.2.5.2 on page 41.
5.2.2.3.1 Description
Either Basic- or Full-CAN mode is configurable. The system monitor is used for set
-
ting the CAN parameters (also refer to section 6.3.2.5.1 on page 40). The internal
CAN module is based on the CAN specifications V2.0 part B. It is possible to transmit
either standard or extended frames (adjustable). The system monitor is used for set
-
ting the bit timing as well as the identifier.
