Configuration
Each card has a unique identifier called card position, which is assigned
(trough hardware pinning) automatically when a card is inserted into a frame.
The card positions are numbered from 1 to 10 from a user point of view. From
a protocol (or software) point of view, the cards are addressed 0-9, but the
user should always see positions 1-10 in menus, etc.
Each frame (if you use more than one) should have a unique frame id,
numbered 0-7 (user and protocol/software wise).

Address setting on each sub-rack
Figure 2 shows the power connections of the frame as well as the RS-422
connections and the DIP-switches for address setting of the frame.
Figure 2: Connector module for the power supply.
Each sub-rack can be assigned an address through the DIP-switches on the
rear. Maximum 8 sub-rack addresses are available.
This address setting only applies when the sub-rack is used in combination
with a GYDA-SC Rack System Controller.
If you have more than 8 sub-racks together, you need several GYDA-SC Rack
System Controller cards.
In order to ensure proper operation of the system, it is
important that no sub-racks controlled by the same
GYDA-SC Rack System Controller card have the same
address set.
Reset the sub-rack after reconfiguring the sub-rack system,
by turning the power off and on again
.
Remember to terminate the last frame with a 110
Ω
resistor.
