Telos ZephyrExpress user manual Communicating, Pin Ground

h

HOT TIP!

This port is configured as DTE, not DCE. This means pins 2 and 3 are wired like a computer instead of as a modem. You can plug in a standard modem, set for auto-answer, to remotely control ZephyrExpress for automated remote broadcasts.

If you want to connect directly to a computer, youÕll need a null modem (a molded plug/jack with crossed wires, available from computer stores) or will want to wire a cable like this, using DB-9 connectors:

ZephyrExpress	signal	Computer
pin 5	ground	pin 5
pin 2	<<< data	pin 3
pin 3	data >>>	pin 2

Communicating

ZephyrExpress speaks standard ASCII text at the selected baud rate.

When you first turn on ZephyrExpress’ power, it sends the message:

Hello world!!

ZephyrExpress V1.2.1/2.36, 16.07.1998 12:39:42

Copyright 1997 TLS Corp. All rights reserved.

Current time is 30.03.1999 15:46:10

cThe V1.2.1/2.36, 16.07.1998 12:39:42 refers to the software version and when

it was compiled, not the current date and time.In this manual, weÕll use Courier RegularDOCUMENTATION NOTE!to indicate text ZephyrExpress is

sending to you.

WeÕll use Courier Bold to indicate text you type into your computer and send to ZephyrExpress. A paragraph mark (¶) indicates you should press the enter or return key.

After a few seconds, you’ll see the ZephyrExpress system prompt:

>>

If you do not get any text, the problem is probably:

•The cable.

•The terminal program itself. Does it work in other communications setups?
