2.4 Notes For RTC
This section summarizes how the RTC
and software differ from that of the RTC
Interface Board and provides the RTC
®
on installing an RTC 4.

Hardware Changes

®
• Standard RTC 4 boards are equipped with an
EXTENSION 1 connector. This connector provides
a 16-bit digital input and a 16-bit digital output
(previously only available via an optional RTC
I/O Board) as well as access to the BUSY status
signal (see "EXTENSION 1 Connector", page
®
• The RTC 4 PC Interface Board is optionally
available with an optical data interface (see
"Optical Data Interface (Optional)", page
eliminates the need for an add-on board to
implement optical data transmission between the
PC interface board and the scan system's
(optional) integrated optical data interface.

Installation Tips

® ®
• RTC 4 and RTC 3 boards in the same
computer cannot be operated simultaneously.
® ®
• RTC 4 and RTC 3 boards use the same Windows
driver. Nevertheless, even if an RTC
already been installed in a computer, the setup
program must still be called again. On the other
®
hand, after an RTC 4 is installed, an RTC
can be operated without newly installing the
driver.
Also follow the guidance in
Up", page 58.

Changes in the Command Set

New Commands
• The new Arc Commands (see page 15)
marking with basic arcs.
• Commands for Status Monitoring and
Diagnostics (see page 38)
monitoring the operational status and
diagnosing the scan system.
• The 16-bit digital input and 16-bit digital output
at the EXTENSION 1 connector can be queried or
set via I/O commands (see
and Output", page 56). Some of these I/O
commands can execute conditional jumps
dependent on the current value of the digital
input, thereby expanding support for structured
programming (see "Conditional List Jumps", page
45). These commands were previously only
available with the optional RTC
Changed Commands
®
The RTC 3 command rtc3_count_cards contains the
designation "rtc3". The RTC
command is called rtc4_count_cards (see page
