Chapter 2: SETUP
Inspection
Your 3PCISD4x serial card was tested for proper operation before
shipment. It should be in perfect mechanical and electrical condition
upon receipt.
The card is normally pre-configured for RS-232 operation on all
ports.
The data clock speed for all 4 ports is set by one jumper to x1
(normal) operation or to x4 operation.
The operating mode of each port on the card is set using 9 jumpers:
5 jumpers select RS-232 operation or RS-422/485 operation, 2
select RS-422 or RS-485 operating modes for Receive and
Transmit, one sets the RS-485 mode driver control for Send Data or
RTS control, and the last selects 120 ohm termination for the RS-
422 or RS-485 Receive. Each of the 4 ports is configured in a
similar fashion.
Refer to Jumper Mode Tables, Appendix B.
Before removing the card from the anti-static protective packaging:
• Discharge any static electricity buildup on your body by touching
a large grounded metal surface or the metal chassis on
equipment connected to earth ground by a 3-wire power cord.
• Avoid touching the gold connectors or other parts on the card
except as necessary to set the configuration jumpers for each
port. After setting the jumpers, ground yourself to the computer
chassis before and while inserting the card.
• Remove AC power from the computer and unplug the power
cord before inserting the card.
• Retain the ESD bag for handling the card. Save the packaging
for storage or shipping.
CAUTION: ELECTROSTATIC SENSITIVE DEVICE
Use ESD precautions for safe handling.
