## CPU-D4 (ROF 157 5124/_)

To put the board in operation mount the system software PROMs in the appropriate positions. The number of battery RAMs mounted on the CPU-D4 board is functionality dependent.

#### Connections on the CPU-D4

Similar to the previous versions this board provides the V.24 interfaces but additionally the RS-485 interface for longer ranges. With the software key (FECU) KDU BS 130 06/_ new functionalities can be accessed.

To connect the RS-485 data interface use plug RNV 321 01 02 be sure to loop RTS with CTS otherwise data is lost if printer is OFF. The range of the interface is up to 1200m.

Several converters may be used but with the following successful tests were accomplished:

- IC-485SI from ARP DATACON and
- 232<->485/422 Converter Plus IC-109AE from Black Box Corp.

#### Feature Enabling Control Unit (FECU)

Connecting this plug activates the appropriate applications and features as ordered depending on the FECU index number. If no plug is connected only a limited Version 4.0 system functionality is available. The indices 2 to 10 always include the Basic Version 4 functionality (index 1).

For detailed information of the features enabled by the different FECUs refer to Facility Description General (15534-ASB 150 02 Uen).
