RELIANCE 57C430B Gateway module

Header J6 is an optional header used to select the SRAM backup power source on the MVME187, if the optional battery is present. (The battery backup for SRAM is optionally available, but only as a factory build and only by special request.) ! Caution If your system is equipped with the optional battery backup, do not remove the jumpers from J6. This will disable the SRAM. If your board contains optional header J6, but the optional battery is removed, jumpers must be installed between pins 1 and 3 and pins 2 and 4 for the factory configuration as shown in Table 3-5.

Serial Port 4 Clock Configuration

 Select Headers J7 and J8 Serial port 4 can be configured to use clock signals provided by the TRXC4 and RTXC4 signal lines. Headers J7 and J8 on the MVME187 configure serial port 4 to drive or receive TRXC4 and RTXC4, respectively .

 ❏ Factory configuration sets port 4 to receive both signals.

❏ The alternative configuration sets port 4 to drive both signals The remaining configuration of the clock lines is accomplished using the Serial Port 4 Clock Configuration Select header on the MVME712M transition module. Refer to the MVME712M Transition Module and P2 Adapter Board User's Manual for configuration of that header

Preparing the MVME187 for Installation 

Refer to the setup procedures in the manuals for your particular chassis or system for additional details concerning the installation of the MVME187 into a VME chassis.

Install/remove jumpers on headers according to the Jumper Settings in this chapter and as required for your particular application. ❏ Jumpers on header J1 affect 187Bug operation as listed in Jumper Settings. The default condition is with all eight jumpers installed ❏ A jumper installed/removed on header J2 enables/disables the system controller function of the MVME187. ❏ Install jumpers on headers J7 and J8 to configure serial port 4 to use clock signals provided by the TRXC4 and RTXC4 signal lines

Ensure that EPROM devices are properly installed in their sockets. ❏ Factory configuration is with two EPROMs installed for the MVME187Bug debug monitor, in sockets XU1 and XU2.
