Additional ZlinkW Troubleshooting Information
Additional ZlinkW Troubleshooting Information
The rest of this section covers connection between the office computer and the terminal. If 
you have successfully linked up to your terminal, you need not read it. Otherwise, please 
read through it before calling for assistance. 
General Information
Always turn off the computer or terminal before removing boards! 
After changing any switch or jumper settings, turn the equipment off, then on, so the 
changes are recognized! 
Your office computer (PC) can talk to the terminal through the telephone lines via modem 
(the standard method), or directly connected via serial ports (the Local connect option). If 
you use one method on your PC, you do not need the other. 
Office Computer
Our ZlinkW software is more sensitive to hardware configuration than terminal programs 
such as CrossTalk. ZlinkW may not work correctly, even when a terminal program runs 
Computer calls, terminal answers, 
responds “connect” but no “ready”
Modem not Hayes compatible
Noisy or too quiet line
Use correct modem
Call terminal and listen to modem 
tone, try different phone lines or 
modem
Connects, but says “Access 
denied”
Password out of sync, typically 
due to using different computers 
with ZlinkW
Disable ZlinkW password 
temporarily. Turn switch 1 on the 
front of the Zetron CPU to the A 
position, then link up, then turn 
back to the B position
Symptom Problem Solution
Note If you are using the Local Connect option, make sure your Edit | 
Locations | Phone Number field says L4800, not just L. The L 
by itself sets the baud rate to 1200. If the COMA/LCL LED on the 
CPU card flashes once, try assigning a different baud rate; for 
exampleL9600.
Note Usually when you are asked to type a line into the computer, as 
shown in some steps below, you need to press Return (or Enter) 
for the computer to accept it.
