QL 3002
Chapter 3 - Hardware Reference
Serial Port Connectors
Optional Parallel Port
Parallel Port Connector
Optional Monitor and Keyboard
The QL 3002 boards provide two standard PC/ATtype COM ports. These ports use Mini DIN 9 female connectors. The following cables may be acquired from Cubix:
Figure 3-1, Mini DIN 9 to Male DB-9.
Figure 3-2, Mini DIN 9 to Male DB-25
A parallel port may optionally be added to function as LPT1 of the QL 3002. One parallel port may be installed per processor. Each port requires a Cubix LPT1 printed circuit board (PCB) adapter and bracket, a panel opening where the DB-25 connector can be installed, and a 20conductor ribbon cable.
Installation
WARNING: Perform a proper shutdown and disconnect power from the system before beginning this procedure.
1. Install the Cubix LPT1 adapter in a panel opening in the system. Typically, an opening provided for an empty board space is dedicated to the LPT1 connector. In this case, install the bracket next to the QL 3002 board requiring the LPT1 port and tighten the screw firmly.
Alternatively, if the LPT1 connector is being installed into a Cubix auxiliary junction panel, the bracket provided with the LPT1 adapter should be removed. Unscrew the connector from the bracket and install the adapter into the desired panel opening.
2. Connect one end of the 20-conductor ribbon cable to the LPT1 header on the QL 3002 board. The pin-one side of the ribbon cable is marked with a colored stripe. Pin one on the QL 3002 is on the left side of the header when the edge connector is down (refer to Figure 3-3). Align the pin-one side of the ribbon cable with pin one on the header.
3. Connect the other end of the ribbon cable to the LPT1 adapter. Pin one on the adapter is labeled with a triangular arrowhead. Align the pin-one side of the ribbon cable with pin one on the adaptor.
4. Plug the peripheral device's cable into the DB25 connector.

Each processor on the QL 3002 will optionally support a VGA monitor and PS\2 keyboard. This requires a Cubix printed circuit board (PCB) adapter and bracket, and a single panel opening where the DB-15 High Density and Mini-DIN 6 connectors can be installed. Both the monitor and the keyboard interfaces are provided on the same PCB adapter; however, a separate adapter is required for each processor. A 14-pin flat ribbon cable is required to connect the monitor and keyboard adapter to the QL 3002.
INSTALLATION
Warning: Perform a proper shutdown and disconnect power from the system before beginning this procedure.
1. Install the Cubix PCB adapter in a panel opening on the system. Typically, an opening provided for an empty board space is dedicated to the monitor and keyboard connectors. In this case, install the bracket next to the QL 3002 board requiring the monitor/keyboard ports, and tighten the screw firmly.
Alternately, if the monitor and keyboard connectors are being installed into a Cubix auxiliary junction panel, the bracket provided with the monitor/keyboard adapter should be removed. Remove the bracket from the connectors and install the adapter into the desired opening.
2. Connect one end of the 14pin ribbon cable to the video/keyboard mux header for the appropriate processor on the QL 3002 board (refer to Figure 3-4). The pin-one side of the ribbon cable is marked with a colored (blue or red) stripe. Pin one on the QL 3002 is on the left side of the header when the edge connector is down. Align the pin-one side of the ribbon cable with pin one on the header.
3. Connect the opposite end of the 14-pin cable to the header on the Cubix adapter board. Pin one on the adapter is indicated in Figure 3-4. Align the pin-one side of the ribbon cable with pin one of the 14-pin header on the adapter board.
4. If a monitor is to be used, plug the monitor's cable into the DB-15 HD connector.
5. If a keyboard is to be used, plug the keyboard connector into the Mini-DIN 6.
