TESTING THE SLIC DEVICE CONTROL LINES
This procedure will test the Control and Data (inputs/outputs), CD1 and CD2, and the three SLIC
device control lines (C3, C4, C5) of the QLSLAC device. To accomplish this you will need two 20-
pin cables to connect H1 to H2 and H3 to H4.
Perform the following steps to test the SLIC device control lines:
1. Set the Wrt/Rd Enable Channel Register buttons so that only channels 1 and 3 are selected.
2. From the QLSLAC Cmds menu, click once on the IO Direction & Read Status button, then do
as follows:
a) Change IOD1, IOD2, IOD3, IOD4, and IOD5 to a "1".
b) Click on the Wrt Input Output Register Direction button.
3. Click on the Wrt/Rd SLIC IO Direction menu option, and do as follows:
a) Change CD1, CD2, C3, C4, and C5 to a "1".
b) Click on the Wrt Input/Output Register button.
4. From the Wrt/Rd Enable Channel Register menu, do as follows:
a) Disable channels 1 and 3.
b) Enable channels 2 and 4.
5. From the Wrt/Rd SLIC IO Direction menu, do as follows:
a) Leave IOD1 through IOD5 set to "0".
b) Click on the Write button.
6. From the Wrt/Rd Enable Channel Register menu, do as follows:
a) Disable channel 4.
b) Enable channel 2.
c) Click on the Rd/CLR Real Time Data Register option. You will see the data pattern output
by channel 1.
d) Disable channel 2.
e) Enable channel 4.
f)
Click on the Rd/CLR Real Time Data Register option for channel 4. You will see the data
pattern output by channel 3
Please remember that the control signals are mapped to the H1-H4 headers in the following
manner:
Table 5–1 CD1x – C5x Control Signal Mapping to H1 – H4 Headers
Control Signal
Mapping Description
CD1x
Routed to pin 13 of header to monitor the status of DET
CD2x
Routed to pin 1 of header Hx as C1 bit for the SLIC device
C3x
Routed to pin 3 of header Hx as C2 bit for the SLIC device
C4x
Routed to pin 5 of header Hx as C3 bit for the SLIC device
C5x
Routed to pin 9 of header Hx as C5 bit of the SLIC device
