SIM Selection for Serial Port B (J15)
Port B of the MVME162P4 Z85230 serial communications controller is
configurable via a serial interface module (SIM) that is installed at
connector J15 on the board. Five serial interface modules are available:
❏
EIA-232-D (DCE and DTE)
❏
EIA-530 (DCE and DTE)
❏
EIA-485/EIA-422 (DCE or DTE)
You can change Port B from an EIA-232-D to an EIA-530 interface or to
an EIA-485/EIA-422 interface (or vice-versa) by mounting the appropriate
serial interface module. Port B is routed (via the SIM at J15) to the 25-pin
DB25 front panel connector marked
SERIAL PORT 2
.
For the location of SIM connector J15 on the MVME162P4, refer to Figure
1-1 . Figure 1-2 illustrates the secondary side (bottom) of a serial interface
module, showing the J1 connector which plugs into SIM connector J15 on
the MVME162P4.
Figure 1-3 (sheets 3-6), Figure 1-4 , and Figure 1-5
illustrate the seven configurations available for Port B.
