Interface adapters
UWS11A interface adapter
Part number
822 689 X
Description
The UWS11A option converts RS232 signals, for example from the PC, into RS485 sig-
nals. These RS485 signals can then be routed to the RS485 interface of MOVITRAC
®
.
The UWS11A option requires a DC 24 V voltage supply (I
max
= DC 50 mA).
RS232 interface
The connection between UWS11A and PC is made using a commercially available se-
rial interface cable (shielded!).
RS485 interface
Max. 32 MOVITRAC
®
units can be interconnected for communication (max. line length
200 m (656 ft)) via the RS485 interface of the UWS11A. Do not connect external termi-
nating resistors as dynamic terminating resistors are already installed.
Permitted cable cross-section:
1 core per terminal 0.20 – 2.5 mm
2
(AWG 24 - 12)
2 cores per terminal 0.20 – 1 mm
2
(AWG 24 – 17)
Dimension drawing
of UWS11A
