OPTIONAL EXTERNAL FUNCTIONS
5.1
GENERAL
When the recorder is fitted with the optional remote control cable, a number of functions of the BD
11E/12E can be remotely controlled. Some of these functions are standard BD 11E/12E functions; some
others only are available when the respective options have been installed. The remote control uses a 15
pin sub D type connector, which is located at the rear side of the recorder. The location of this connector
is as shown in figure 1 in chapter 3 PREPARATIONS FOR USE. Its pins carry the signals, which belong
to the involved functions. Each of these signals is described in section 5.4 SIGNAL EXPLANATION.
5.2
OPTIONS
For special applications, the following types of options are available.
1. Pen Offset Compensation / RS232
2. Electrical pen-lift & remote control connector (BD11E/12E)
When both POC and remote control are built in, then the serial output of the channel with POC is
available.
These options have to be purchased separately. The POC and remote control are described below. The
electrical penlift is described in section 4.2.2.6. For a complete description, which covers installation and
user information of the POC / RS232 option, refer to appendix B in this manual.
5.2.1
Pen offset compensation (optional)
Because of the nature of the BD 12/12E recorder, the two pens have a different position with respect to
the time axis of the recorder. The pen of channel 1 is always 2.5 mm behind the pen of channel 2. When
two time functions are drawn, using the BD 12/12E recorder with no POC installed, the curves in fact are
shifted over a distance of 2.5 mm with respect to each other. This could cause interpretation problems. If
this is the case, or if this just is not desired, the POC should be installed. The circuitry in this option
delays the values of channel 1. The delay comprises 50 steps of 0.05 mm, which makes 2.5 mm.
5.2.2
Serial data output (BD 11E/12E)
When the POC and remote cable option are installed, input information for one channel is available in
digitised form, for digital information of both channels two POC-options should be installed. This
information can be directly read by any computer with an RS232-C interface. Data is sent in a time-
multiplexed form. After each step of the paper transport mechanism, a digitised value for channel 1 and
one for channel 2 are transmitted.
5.3
I/O Circuitry specifications for remote control (optional)
All incoming signals are received by input logic as shown in figure 8.
