PQ-8P, PQ-8S

3. Installation

Before connecting the PQ-8 to the printer, verify that the printer func- tions properly by performing a printer self-test. Consult the printer’s user’s guide for instructions on how to start and evaluate the self-test.

If the printer functions properly, proceed with the installation of the PQ-8.

WARNING

Electrical current from power lines and cables connecting the interface, the printer, and the PC can be hazardous. To minimize the danger, follow the instructions below.

To install the PQ-8P:

1.Power off the printer and PC (if used) and disconnect the power cord(s).

2.Use the configuration switches located on the PQ-8P’s front panel to select the desired output protocol and the device address for the PQ-8P. Refer to Table 4-3for switch settings. Make sure the host has been configured for the same device ID and cable address (see

Section 4.1, Host Configuration).

3.Connect the parallel cable from the PQ-8P’s “Parallel Out” connector to the printer’s parallel port.

4.If the sharing port of the PQ-8P is used, attach the parallel cable now. Note that a PC or LAN connected to the PQ-8P’s sharing port should always be powered on when the interface is operating.

5.Connect the wall mount transformer from the outlet to the interface’s “9V” connector. Connect the power cord(s) to the printer and PC (if used).

6.Power on the PQ-8P, then the printer. The PQ-8P’s green LED lights labeled “Power” and “Printer On Line” should be on.

7.Print a PQ-8P self-test. First, power off the PQ-8P. Then, set configuration switch SW1:8 (far right) to the “” position. Power on the PQ-8P. After the two-page self-test prints, set switch SW1:8 back to the “o” position, then cycle the power one more time.

8.Refer to the self-test printout to determine which configuration parameters need to be altered. Change these parameters by using the setup software or Host/PC download commands.
