1 Overview
This manual describes technical features and function of the evaluation unit with serial
interface cat. no. 077910 type CIA3SX1R1G08 and the communication with PC or SPS.
The transfer telegrams for the commands
- Program (write) data carrier
- Read data carrier
are based on the 3964R transfer procedure [1].

2.3 Notes on installation
· Do not connect the evaluation unit CIA3... as well as the read/write head CIT3... as long
as power is on.
2.4 Settings
2.4.1 DIP switch settings
The settings of the DIP switches is only checked after the power-on cycle.
So it makes no sence to change the DIP switch setting during operation of the unit.
Changes are only valid after a power-off / power-on cycle.

2-4 (8) ON= Data carrier read-only
OFF= Data carrier read/write
General note:
All presently un-used switches must be set “OFF”. Thus, possible problems can be avoided with
functions which may be added in the future.
OFF Data carrier read/write
2.4.2 Interface setting
For the pre-setting of the interface type, the rotary switch "S3" is responsible.
Default setting is RS232

3 Basic telegram structure
Each command and any related data blocks are transferred within the telegram frame in
accordance with procedure 3964R from and to the ident system (figure 1).
With Protocol 3964R, the relevant receiver acknowledges the received telegram by
returning an acknowledgement character (DLE). In the case of negative acknowledgement
(NAK), the entire protocol is repeated. If it is not possible to transfer the protocol error-free
after a total of six attempts, the operation is aborted.
