Setting up a Premvet 5 to communicate with a Idexx Vettest 8008

This document contains the technical information required for wiring up an Idex VetTest 8008 to transfer information to a Premvet 5 Unix System.

There are two steps:

a) Edit the file /etc/default/Premvet 5 to include a line :

VETTEST=/dev/tty0a00

Indicating on which port the Vettest is connected.

The file should then look like:

# Main Premvet 5 script to set startup variables

# Where are the main data files located
VETSYS=/m/vetdata

# Location of vet test machine
VETTEST=/dev/tty0100

b) Re-boot the system.

The vettest software runs a daemon which runs when the machine starts up. During the re-boot you will see a line

Setting up VetTest link on /dev/tty0a00 PID: 1234

Refer to read218d for the operational instructions.

VetTest Wiring

The connection to the vettest machine should use all the RS232 signals:

     DB 25  DB 25                  DB9   DB25
        2 -- 3                      1 -- 8
        3 -- 2                      2 -- 2
        4 -- 5                      3 -- 3
        5 -- 4                      4 -- 6
        6 -- 20                     5 -- 7
        7 -- 7                      6 -- 20
       20 -- 6                      7 -- 5
                                    8 -- 4

You do not need to worry about Baud Rate/Parity or Stop bits these are handled by the monitoring software.

Note: If the VetTest has a VetCom unit attached then the link is via an RJ45 connector on the rear of the VetCom unit. It does not matter which connector is used.

          3           8       5
