External signal input
APX-3302 can interface with peripheral device by using expansion connector (CN6).
The signal names and the interfaces are shown below.
Signal name
Function
ExTrg_1
TTL level: External trigger input terminal for Ch.1.
It is below available for three kinds of uses.
- For Ch.1 Image input start trigger
- For Ch.1 CC generating trigger
- For Ch.1 Encoder startup trigger
A negative going edge is recognized as a trigger.
ExTrg_2
TTL level: External trigger input terminal for Ch.2.
It is below available for three kinds of uses.
- For Ch.2 Image input start trigger
- For Ch.2 CC generating trigger
- For Ch.2 Encoder startup trigger
A negative going edge is recognized as a trigger.
Enc.A±
RS422 level: Encoder input terminal.
It is available as encoder A phase for Ch.1 and Ch.2.
Enc.B±
RS422 level: Encoder input terminal.
It is below available for three kinds of uses.
- Encoder B phase for Ch.1 and Ch.2
- Image input start trigger for Ch.1
- CC generating trigger for Ch.1
Enc.Z±
RS422 level: Encoder input terminal.
It is below available for three kinds of uses.
- Encoder Z phase for Ch.1 and Ch.2
- Image input start trigger for Ch.2
- CC generating trigger for Ch.2
Diff±
RS422 level: Common external trigger input terminal.
It is below available for three kinds of uses.
- Image input start trigger for Ch.1 and Ch.2
- CC generating trigger for Ch.1 and Ch.2
- Encoder startup trigger for Ch.1 and Ch.2
A negative going edge is recognized as a trigger.
GP_IN1
TTL level: General-purpose input terminal.
It is available as an interruption factor. An interrupt occurs in a negative going edge.
IN_RES1
TTL level: General-purpose input terminal.
The H/L state of a terminal can be checked with a register.
GP_OUT1
TTL / open-collector level: General-purpose output terminal for Ch.1.
It is below available for three kinds of uses.
- Outputs in general
- Stroboscope output for Ch.1
- Capture flag (Output "L" level while capturing) for Ch.1
GP_OUT2
TTL / open-collector level: General-purpose output terminal.
It is below available for three kinds of uses.
- Outputs in general
- Stroboscope output for Ch.2
- Capture flag (Output "L" level while capturing) for Ch.2
SYNCLT_IN
TTL level, synchronizing-signal input terminal between frame-grabbers.
Connect the SYNCLT_OUT terminal of a master frame-grabber
(synchronizing-signal generating origin).
