Serial Ports 1-4 DCE/DTE Configuration

Serial ports 1 through 4 are configurable as modems (DCE) for connection to terminals, or as terminals (DTE) for connection to modems. The MVME712M is shipped with the serial ports configured for DTE operation. Serial port DCE/DTE configuration is accomplished by positioning jumpers on one of two headers per port. The following table lists the serial ports with their corresponding jumper headers.

Table 1-2. MVME712M Port/Jumper Correspondence

Serial Port	Board	Panel Connector	Jumper
	Connector		Header
Port 1	J7	SERIAL PORT 1/ CONSOLE	J1/J11
Port 2	J8	SERIAL PORT 2/ TTY	J16/J17
Port 3	J9	SERIAL PORT 3	J13/J14
Port 4	J10	SERIAL PORT 4	J18/J19

The next six figures illustrate the MVME2603/2604 base board and MVME712M transition module with the interconnections and jumper settings for DCE/DTE configuration on each serial port.

Serial Port 4 Clock Configuration

Port 4 can be configured via J15 (Figure 1-4)to use the TrxC4 and RtxC4 signal lines. Part of the configuration is done with headers J16, J17, and J20 on the MVME2603/2604 (Figure 1-9and Figure 1-10).
