3.1.6 Extension Connectors (J8-J12)
The M3A-HS11 includes the through hole for mounting extension connectors to which the I/O pins of the SH7211
are connected.
MIL standard connectors can be connected to J8-J12, allowing the user to connect with extension boards or
monitor the SH7211 bus signals.
The address signal of SH7211 is connected to the terminal J9 connector through J8 connector. Moreover, the bus
signal of SH7211 is connected to the terminal J12 connector through J11 connector. J8 connector and J11 connector
are mounted for signal measurement by measuring instrument. When an extension board is made, it is recommended
to use the J9 and J12 of terminal connector to prevent the waveform distortion occurred by the reflection of signal.
Figure3.1.8 shows a pin assignment of extension connector.
