Front View
The JRS422 connector provides the PMAC with the ability to communicate both in RS422 and RS232. In addition,
this connector is used to daisy chain interconnect multiple PMACs for synchronized operation.
Jumper E110 selects between RS-232 or RS-422 signal types.
Jumper E111 enables or disables the use of the Phase, Servo and Init lines
*
Note: Required for communications to an RS-422 host port
** Note: Required for communications to an RS-422 or RS-232 host port
*** Note: Output on card @0; input on other cards. These pins are for synchronizing multiple PMACs together by
sharing their Phase and Servo clocks. The PMAC designated as card 0 (@0) by its jumpers E40-E43, outputs its
clock signals. Other PMACs designated as cards 1-15 (@1-@F) by their jumpers E40-E43, take these signals as
inputs. If synchronization is desired, these lines should be connected even if serial communications is not used.
