Chassis Address Selection

Each APS chassis must be assigned a block of addresses for its 1557 APS

cards so that the 1559 APS Manager may communicate with them. The DIP

switch located on the front panel of the 1250 Alarm and Power Card is used

to provide up to 8 chassis addresses. These addresses are used by the APSM

to poll and send commands to the 1557 cards.

Three out of the four switches (S2, S3, and S4) are set to one of the 8 pos-

sible address codes as shown in the table to the right. The DIP switch posi-

tions are number S1 through S4, with S1 on top and S4 on bottom. Note that

S1 is not used.

The first unit address (1557 card) in the chassis is the base address plus 1.

For example, if S2, S3, and S4 were all set to 0, the first unit address in the

chassis would be ‘1’ (0 + 1).

1250 Front View

NOTES: 1250 cards that are Rev. 2.63 or

higher add the capability to maintain alarm

card functions (front panel indicators, switch

functions, and relay operation) even when

Fuse A and B are open. This is possible be-

cause these cards have the alarm circuitry

wired to the ‘hot’ side of the incoming A and

B external power source(s). In early revi-

sions, the 1250 alarm functions were only op-

erational if one or more of the front panel

fuses were functional (not blown).

Earlier versions of the 1250 card were called

1555P cards. The function of each card is the

same.
