3.4 Battery Block for CMOS Memory Modules

The battery port is designed in double to be able to change the battery without an inter-

ruption even if the supply is switched off. The plug-in ports are separated when deliv-

ered in order to avoid an uncontrolled exhaustion during storage.

The discharge degree of the battery block is not defined.

The replacement date is to be entered on the battery block by the user / commissioner.

3.5 Equipping the PMB Area

There are 7 slots available in the PMB area (Figure 141) (memory bus, DUM 024 wir-

ing printed board).

Slot no. 57 ... 81 7 x 4T, memory bus node (C64F)

SC 832, SF 8128, MPV 003, KOS 882

Slots which are not used can be occupied by expansion modules which are not PMB

nodes if the adapter connector lies in the upper area of the F modules (e.g., UVL 841).

3 slots (expandable9 of the memory area are equipped with guide parts for such ex-

pansions for the direct connection of MDL 48 cables.

3.6 Equipping the PEAB Area

The PEAB area (Figure 141) (I/O bus, DUA 024 wiring board) includes 7 slots with the

following reservation:

Slot no. 21 PEAB networking DKV 023 or I/O component (C64F)

25 ... 41 5 x 4T, I/O bus node (C64F)

Slot 6 (7) ... 2, 32 bits

45 4T, UKA 024 (Monitorings, LS/V.24)

Slot reference 1, (C64F + E48F)

Slot no. 33 = slot reference 4 is to be used in preference to operate the DBK 021 oper-

ating console which is 12T wide (EQL list entry), whereby the neighbouring slots of 3

and 2 are physically blocked. The DBK 021 occupies all 4 subaddresses (this must be

taken into consideration for the secondary subrack.

3.7 PEAB Expansion / Extension

A DTA 025 subrack (slot references 17 ... 32 only) is controlled by the non-amplified

ALU bus via an MDL 66.1 bus cable for the PEAB expansion (see (3) in Figure 142

and Figure 143). The DKV 023 bus driver is not required here. The DTA 025 is coupled

via a DKV 023 to be equipped and the MDL 67 bus cable for the PEAB networking

(max. 20 m and slot references 33 ... 160) (see (4) in Figure 142).
