In addition to key-controlled processing of the data carriers, it is also possible to perform
read and write operations from a PC or laptop over the serial interface of the Handy Pro-
grammer. The Handy Programmer then functions just like a BIS Processor.
The PC and Handy Programmer are connected using a BIS C-522 *) cable. Communication
between the Handy Programmer and the laptop / PC uses a specific protocol (see 30).
For details on the individual telegrams see 31ff.
Menu point 4 "File" is se-
lected in Main Menu 1 and
menu point 3 "Trans." acti-
vated in the following file
menu to start this function.
All commands for reading and writing (L, Z, C and P) as well as the Acknowledge com-
mand (Q) can, depending on the configuration, be terminated either with a BCC block
check or with Carriage Return 'CR'. The Handy Programmer then also terminates all trans-
mitted characters using the selected termination type.
