Base Station Setup Parameters
Typically the Base Station will need no changes.
Baud Rate
300 0
600 1
1200 2
2400 3
4800 4
9600 5
19,200 6
• This is the communication rate between the host computer and the Base
Station. The higher the Baud Rate the shorter the distance between your
Base Station and host computer. 9600 baud (the default) is typically good for
100-200 feet or more, while 19,200 baud cannot be transmitted more than
50-100 feet. If you are planning to use an extension cable of 80 feet or more,
cut all pins except Transmit, Receive, Ground, and Shield.
• A lot of your success will depend upon the quality of your cabling and the
level of interference from other electrical equipment near the cable. Electric
motors (on start-up) can be particularly troublesome. If you need more
distance, use inexpensive 422 line-drivers.
Xon/Xoff Sensitive
No 0
Yes 1
• If the Base Station is set for NO, it transmits ASCII 19 for its' "BASE
INITIALIZED" message and ASCII 17 for its' "TERMINAL ID NOT
SIGNED ON" message. Unfortunately, these ASCII characters conflict with
any multi-user system utilizing the XON/XOFF protocol.
• The alternative setting, 1, should be used whenever you are operating on a
system that is XON/XOFF sensitive, such as an HP3000 or other
minicomputers. It causes the Base Station to transmit ASCII 20 (instead of
19) for the "BASE INITIALIZED" message and ASCII 16 (instead of 17) for
the "TERMINAL ID NOT SIGNED ON" message.
• The default setting for flow control for a serial port in Windows
95/98/2000/ME is XON/XOFF, so consider using the Alternative Yes setting
if running Windows.
