SECTION 15 – INTER CARD COMMUNICATIONS
Universal Card Slots
All card slots are universal in application therefore all card types can be inserted from
the front of the rack using the associated card guides and once inserted each card
automatically connects to the customer terminals located on the rear of the chassis via
the motherboard.
Each card slot on the chassis motherboard is equipped with a dedicated 2 way DIL
switch located on the inside face of the chassis motherboard.
This switch must be set to the appropriate setting for each application.
If adjacent card slots are equipped with P925TS-I Input Cards the switch should be set
to the off position, which will disable the local RTK communications bus between
adjacent slots.
However if adjacent card slots are equipped with P925TS-I Input and P925TS-O or R
Output Cards the switch must be in the on position.
With switch 1 and 2 in the on position local RTK communication data is passed
between the cards to allow the inputs to activate the associated outputs (Lamp/LED or
relay).
