User-side Connector Descriptions

This section describes the PC-style connectors that protrude through the end cap for user cable connections.

Serial Ports 1,2,3,4

Serial ports 1 through 4, designated on the silkscreen as SER1, SER2, SER3 and SER4 are male DB9 connectors and support the RS232 protocol only. These signals come from the CPU card.

6 DSR - Data Set Ready
7 RTS - Request to Send
8 CTS - Clear to Send
9 RNG - Ring Indication

Serial Ports 5,6,7,8

Serial ports 5 through 8, designated on the silkscreen as SER5, SER6, SER7 and SER8 are male DB9 connectors. The signals are provided by an expansion serial I/O card in the stack. If a Diamond Systems Emerald MM-4 is utilized, these connectors support RS232, RS422 and RS485 protocols.

Power In

Power input is a female Molex Mini-fit connector, part number 39-30-2045. If the system is powered by a 5v supply, use pin 1 to supply power. If the system is powered by a variable voltage DC supply, use pin 4 to supply power. See Section 6, Power Interface, for additional power connection information.

Data I/O Port 2

Data I/O port 2 is also a latching "Centronics" 50-Pin Female connector which provides a 1-to-1 mapping from the signals provided by an expansion I/O board.

Note: Pay particular attention to the pin mapping, because it may not match the pin mapping on your expansion I/O board.
