6. Parameter setup with SW1
Since the required configuration is loaded only du-
ring the start of the device, it must be set up by
means of the appropriate DIP switches (SW1 see
chapter 5.1)
prior to
switching on the operation
voltage.
6.1 Operating mode ("RS485 mode")
(
SW1.1 = OFF
; Output of position value and para-
meterization via RS485)

No function in RS485 mode
6.2 SSI operating mode ("SSI mode")
(
SW1.1 = ON
; output of position value via SSI)
The cycle inputs of the SSI interface have been re-
alised opto-decoupled and have a 150 Ohm series
resistance. The red "SSI cycle" lightemmitting di-
ode is lighted as soon as a cycle signal is applied,
even if the 24 V supply of the translation module
has not been switched on yet. The SSI data out-
puts correspond to the RS422 interface.
DIP Position Description
1
ON
SSI mode
2
OFF
ON
Position value is output in Gray
code (default)
Position value is output in binary
code
3
OFF
POSITIVE counting direction
(default)
NEGATIVE counting direction
The SSI operating mode enables the simultaneous
use of the RS485 interface in the Service Standard
Protocol.
6.3 Mode-independent DIP switches
The following DIP switches are continuously polled
while the system is being supplied from the 24V
mains. After actuating a switch there is a time
delay of approx. 2s. If no switch position is chan-
ged during this time, the setting is taken over and
processed.
