Chapter 5 System Configuration
450L-APR-UN-8 Connection
Plug-in
Tabl e 27 shows the function and default settings for the M12 8-pin muting
receiver plug-in (450L-APR-UN-8) inserted in a 450L transceiver stick.
Table 27 - Function and Default Settings
For the UNIV plug-in, if pin four and pin eight are short circuited (transmitter
mode), the DIP switch settings have no impact on the transmitter functionality.
Confirmation of a New
System Configuration
Perform a confirmation procedure of a new configuration when you reinsert the
plug-in to the light curtain stick with a changed DIP switch setting. The request
for such a confirmation is displayed via a 1 Hz red/green blinking STS status
indicator (Figure 31
).

IMPORTANT The confirmation procedure is not required when the receiver stick is
operated the first time (brand new receiver). The STS status indicator flashes
red/green when a confirmation is required.
Confirmation of a system configuration needs only be performed when the
receiver stick was previously operated with another configuration or when
the receiver stick was previously operated with another transmitter.
If the receiver plug-in is exchanged with a new plug-in with the same plug-
in type and DIP switch settings as the original one, no confirmation
procedure is required.
Also, no configuration confirmation procedure is required for a complete pair
of 450L transceiver sticks out-of-the-box.
