REXROTH HDS03.2-W100N-HS79-01-FW Driver module

The Z85230 supplies an interrupt vector during interrupt acknowledge cycles. The vector is modified within the Z85230 according to the interrupt source. Interrupt request levels are programmed via the MCchip. Refer to the Z85230 data sheet listed in Chapter 1 and to the MCchip Programming Model in the MVME162 Embedded Controller Programmer’s Reference Guide for further information. MVME162 Serial Port 1 Port A of the Z85230 is interfaced as EIA-232-D DCE (data circuit-terminating equipment) and is routed to the 25-pin DB25 connector marked SERIAL PORT 1/CONSOLE on the MVME162 front panel. Port A is also routed to a DB9/RJ11 (on the MVME712x) or DB25 (on the MVME712M) connector on the MVME712 series transition module. It is identified there as Port 2.

Although both ports are connected to the same Z85230 Port A

 there are several differences between them: 

❏ On the MVME162 front panel, Port 1 can be connected to the TxC and RxC clock signals which may be present on the DB25 connector. These connections are made via header J11 on the MVME162 board (see Figures 2-3 and 2-4 in Chapter 2). The TxC and RxC clocks are not available at Port 2 on the MVME712 series transition modules. 

❏ On MVME712x transition modules, Port 2 can be routed either through a DB9 DTE serial interface or (if the module is so equipped1) through the onboard modem and its standard RJ11 (Telco) jack. These connections are made via jumper headers J16 and J17 on the MVME712x. 

❏ On MVME712M transition modules, Port 2 can be configured as either a DCE or a DTE serial port via jumper headers J16 and J17 on the MVME712M.

MVME162 Serial Port 2 

Port B of the Z85230 is configured via a serial interface module which is installed at connector J10 on the MVME162 board. Four serial interface modules are available: 

❏ SIM05 and SIM06 (EIA-232-D DTE and DCE respectively) 

❏ SIM07 and SIM08 (EIA-530 DTE and DCE respectively)Port B is routed (via the module at J10) to the 25-pin DB25 connector marked SERIAL PORT 2 on the MVME162 front panel. Port B is also routed to a DB9 (on the MVME712x) or DB25 (on the MVME712M) connector on the MVME712 series transition module. It is identified there as Port 4.
