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

To put the board in operation mount the system software Flash PROMs in the appropriate positions. The number of battery RAMs mounted on the CPU-D4 board (default one 512 KB RAM) is functionality dependent. After you have completed the system configuration, please connect BMS to the system and check the remaining EEPROM memory.

If you have less than 20% of the total capacity free, it is recommended to add the 2nd RAM (extremely seldom)

#### Connections on the CPU-D4

For connection of Temparture sensor kit, see chapter Temperature Sensor

The ALARM input is optically isolated and the voltage has to be between 20 - 60 VDC. The ALARM output is equipped with an open collector transistor with a capacity of 20 mA at 12 VDC (Maximum 14 VDC).

Similar to the previous versions this board provides the V.24 interfaces but additionally the RS-485 interface for longer ranges.

To connect the RS-485 data interface use plug RNV 321 01 02 to be sure to loop RTS with CTS otherwise the 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 a limited system functionality
(Release 8 + some minor features) is available. The index 1 of the FECU series always covers the basic version of a certain Software Release. The indices 2 to 10 are focusing on certain applications such as “Networking” and “CTI”, they always have the basic version included.

Available FECUs:

- KDUBS 130 06 / 1-10 (ASB 150 02 R9, R10)
- KDUBS 130 07 / 1-10 (ASB 150 02 R11)
- KDUBS 130 12 / 1-10 (ASB 150 02 R12)
- KDUBS 130 13 / 1-10 (ASB 150 02 R13)

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