12. Send “T
lf
” (Trigger) to the 73A-308.
13. The voltage at pin-49 will remain at +5 V.
14. Send “R;E;D
lf
” (Reset, Enable and then Disable) to the 73A-308.
Repeat steps 2 thru 14 for each TTL trigger line 0–7 by substituting the TTL in and TTL
out line of the TS command.
Interrupts Test
This test the capability of the 73A–308 to generate interrupts on the VXI backplane.
1. Send “R;E;D
lf
” (Reset, Enable and then Disable) to the 73A-308.
2. Send a WORD SERIAL COMMAND “Read STB” (command 0xCFFF) to the
73A-308 and the query byte returned will have bit 6 cleared ignore all other bits. If
this is the case then an interrupt has not been generated, otherwise the test failed.
3. Send “IE
lf
”(Enable interrupts on syntax errors) to the 73A-308.
4. Send “ASASAS
lf
”(illegal command) to the 73A-308.
5. Send a WORD SERIAL COMMAND “Read STB” (command 0xCFFF) to the
73A-308 and the query byte returned will have bit 6 set (decimal 64) ignore all other
bits. If this is the case then an interrupt has been generated, otherwise the test failed.
6. Send “R;E;D
lf
” (Reset, Enable and then Disable) to the 73A-308.
7. Send a WORD SERIAL COMMAND “Read STB” (command 0xCFFF) to the
73A-308 and the query byte returned will have bit 6 cleared ignore all other bits. If
this is the case then an interrupt has not been generated, otherwise the test failed.
8. Send “TS 0,0
lf
” ( Trigger Setup, TTLTRG0 IN, TTLTRG0 OUT) to the 73A-308.
9. Send “IT
lf
”(Enable interrupts on external trigger) to the 73A-308.
10. Send “C72;E
lf
” (Close Relay Driver 72, Enable outputs) to the 73A-308.
11. Send “T
lf
” (Trigger) to the 73A-308.
12. Send a WORD SERIAL COMMAND “Read STB” (command 0xCFFF) to the
73A-308 and the query byte returned will have bit 6 set (decimal 64) ignore all other
bits. If this is the case then an interrupt has been generated, otherwise the test failed.
13. Send “R;E;D
lf
” (Reset, Enable and then Disable) to the 73A-308.
