Interface Board 6841H1/H2/H3
Interface Board 6841H1/H2/H3 |
|
The board contains several functional modules for different potential adaptations and also for the output of individual information like second pulses, DCF77-pulse signal etc.
Three different extension levels are available:
Board 6841H1
On this level the board contains the following functional modules:
- one conversion step from RS422 signals to a TTY interface
- one conversion step from RS422 signals to RS232 signals
- two optical coupler outputs for customer specific signals
- two relay outputs for customer specific signals
- one 24V DC/DC transformer for the voltage supply for the output of active signals
All the signals are led to a 25-pole SUB-D female connector.
Board 6841H2
This extension level contains all the functional modules of the board 6841H1. Additionally the board contains a converter from RS422 signals to optical fiber for synthetic cables.
Board 6841H3
This extension level contains all the functional modules of the board 6841H1. Additionally the board contains a converter from RS422 signals to optical fiber for glass fiber cables.
