RS232/RS485 and 422
Table 6: Serial Signal Configuration
Interrupts: Link 2
LK2A
Sends the interrupt from the SCCs to PCbus IRQ3
LK2B
Sends the interrupt from the SCCs to PCbus IRQ2
No jumper means that the PCSER4 cannot generate any interrupts.
If you intend to use the Arcom driver software, it may be necessary to insert a jumper into one of
these link positions.
We recommend that you only insert a jumper into LK2, if you intend to use interrupts from the
SCCs and are experienced at writing PC interrupt-handling software.
