8. Supplementary operation manual for
open and closed interface
(February 1994, Erg. 31.8.1994)
The addendum describes the interfaces and documents the
modifications of the Operating Instructions for the Counter regarding
the additional open interface. Corresponding to the 1st. addendum
to file number: 1.62-3251.11 IVO-040293 dated 16.03.1995.
8.1 The closed interface
The closed interface is of the RS232 type. It allows to send data that
can be calibrated to the printer. The interface parameters cannot be
modified and are to be set at the printer as follows: Parity off, 7 data
bits, 1stop bit, Baud rate: 4800 Baud. Configuration of the interface
data at the printer: DIL-switch 7 and 8 „ON" .
Features of the RS232 interface:
– asymmetric
– 3 lines
– Point-to-point connection: 1 emitter and 1 receiver
– Data transmission distance: max. 30 m
8.2 The open interface
The open interface is of the RS485 type. It is possible to send the
commands documented in the „Description of the open interface"
for remote control to the counter. The interface allows to call up data
and to change the programming of parameters not relevant for the
values to be calibrated.
Features of the RS485 interface:
– symmetric
– 2 lines
– Multipoint connection: Emitter and receiver (max. 32 devices)
– Data transmission distance: max. 1500 m
8.3 Modifications of the operating instructions
8.4 Modifications in Chapter 2: „Get to know your counter"
All indications regarding interfaces refer to the closed interface.
8.5 Modifications in Chapter 3: „Counter connection"
All indications regarding interfaces refer to the closed interface.
8.6 Modifications in Chapter 3.5: „Interface connection"
The closed interface:
Set the interface parameters as indicated under Chapter 1.1.
The contacts 23-26 are assigned to the closed RS232-type interface.
The open interface:
It is possible to choose the interface parameters as described in the
Operating Instructions under lines 43 - 46.
Interface parameters are:
- the speed of transmission (Baud rate)
- the parity bit
