Receiving Modem (SIXNET VT-MODEM-1) Setup Procedure :
Use Window’s HyperTerminal to communicate to the modem.
Note:
For information on how to use HyperTerminal, please consult the SIXNET VT-MODEM
online help guide located on the SIXNET CD in the Product Catalog
.
Settings can be changed by connecting the straight through cable, which comes as part of the Industrial
Modem package (VT-CABLE-MDM) to the serial port on the modem and the serial port of the computer
(i.e. serial port COM1).
Important:
Choose the baud rate that matches the PLC or other device that will be connected to
the modem. Anytime a setting is saved using &W0 or &W1, the RS232 baud rate is memorized
by the VT-Modem. The saved baud rate will be used for future communications with any
attached device that does not initiate communications with the modem (such as most PLC’s).
To check communication, type
AT <
Enter
>.
OK
should appear.

(Note: Using a Rev 1.09 VT-MODEM-1, Rev 1.04 VT-MODEM-2, Rev 1.02 VT-MODEM-3 may
require different AT commands. Loading pre-configured settings from the latest VT-MODEM Setup
Wizard will eliminate the need of AT commands.)
Loading Pre-Configured Settings:
SIXNET provides a pre-configured file (AB_Micrologix1500.6ms and AB_Micrologix1000.6ms) that
can be loaded to the modem via the VT-MODEM Setup Wizard; a Setup Utility included with every
SIXNET VT-MODEM-#. The AB_Micrologix1500.6ms file is located on the latest SIXNET CD, from
your local SIXNET representative, or in the modem section at
www.Get2Support.com
.
To load the pre-configured file into the modem click on the “Open Configuration File” button in the
Load Configuration
window, and open the AB_Micrologix1500.6ms file (See Screen Shot 1). Select the
communications port the SIXNET VT-MODEM-1 is connected to (COM 2 in this case) in the
COM
Parameters
window (See Screen Shot 2). Load the configuration into the modem using the “Write
Configuration to the Modem” button in the
Write Configuration
Window (See Screen Shot 3).
