9.With the PQ-8P powered off, attach the auto-terminating twinax V-cable to the PQ-8P.

10.Connect the twinax host cables to the V-connector. The twinax V-connector is automatically terminated when one cable is attached and automatically cables through when two cables are attached.

To install the PQ-8S:

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

2.Use the configuration switches on the PQ-8S’s front panel to select the desired output protocol, the device address, and the serial output parameters for the interface. 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 serial cable from the PQ-8S’s “Serial Out” connector to the printer’s serial port.

4.If the sharing port is used, attach a second serial cable to the PQ- 8S’s “Serial In” port. Note that a PC or LAN connected to the PQ- 8S’s sharing port should always be powered up when the PQ-8S is operating. In addition, the PC/LAN and the PQ-8S must be using the same serial parameters. Refer to Section 5.2, Printer Sharing, for more information.

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-8S, then the printer. The PQ-8’s green LED lights labeled “Power” and “Printer On Line” should be lit. If the sharing port is used and handshaking requirements are met, the LED labeled “PC/LAN Ready” should also be on.
