Figure 1-5 illustrates the placement of the switches, jumper headers,
connectors, and LED indicators on the MVME1600-011. Manually
configurable items on the base board include:
Serial Port 4 DCE/DTE selection (J7)
Serial Port 4 clock selection (J8, J15, J16)
Serial Port 4 I/O path selection (J9)
VMEbus system controller selection (J10)
Serial Port 3 I/O path selection (J13)
General-purpose software-readable header (J14)
Serial ports on the associated MVME712M transition module are also
manually configurable. For a discussion of the configurable items on the
transition module, refer to the user's manual for the MVME712M (part
number MVME712M) as necessary. The MVME1600-011 has been
factory tested and is shipped with the configurations described in the
following sections. The required and factory-installed Debug Monitor,
PPCBug, operates with those factory settings.
Serial port 4 on the MVME1600-011 is DCE/DTE configurable. Header
J7 sets a configuration bit for serial port 4 in the Z8536 ID register.
Software reads the bit as either a DCE or DTE value and configures the
port accordingly. Header J7 may be configured as follows.
J7

Jumper On = DTE in ID Register
(factory configuration)
