4.4.4 MARKING ON THE FLY
Connector
The MARKING ON THE FLY connector provides,
among other things, encoder inputs for incorpo-
rating encoder signals. Together with the optional
Processing-on-the-fly-functionality, this enables laser
material processing of moving workpieces (e.g. on a
moving conveyer belt or rotating disk, see
).

Encoder Inputs
The RTC
®
5 provides two encoder inputs ENCODER X
and ENCODER Y. Each of the encoder inputs are
designed for a pair (1, 2) of standardized RS422
differential signals (also see
).
External Control Signals
The external control signals /START2 and /STOP2
(TTL active-low) are referenced to PC ground (GND).
Both input signals are connected internally to +5 V
via pull-up resistors. Refer to the section
Stopping Lists via External Control Signals and
Master/Slave Synchronization", page 209
Analog Output Port
The 12-bit analog output port ANALOG OUT2 at
pin (14) is identical to the ANALOG OUT2 output port
at the LASER connector (see
). It is referenced
to PC ground (GND).
BUSY Status
The BUSY OUT signal at pin (13) is identical to the
BUSY OUT signal at the LASER connector (see
). The signal is referenced to GND.
Slot Cover (Optional)
SCANLAB recommends using an additional slot cover
for using the inputs and signals of the
MARKING ON THE FLY connector. A suitable slot
cover with a 15-pin D-SUB connector is available from
SCANLAB.

connector.
4.4.5 RS232 Interface
The “RS232” connector provides an RS232 interface
for controlling external equipment. The pin-out is
shown in
Max. input voltage range: –25 V … +25 V
Max. output voltage range: –13 V … +13 V
The signals are referenced to PC ground GND.
The command
baud rate (default setting: 9600 baud). The other
parameters cannot be altered (data bits: 8,
start bits: 1, stop bits: 1, parity: none). For
programming signal output and input via the RS232
interface, see
