•
The TMS scanner PC may be provided with serial communication ports for up to eight channels.
They are indicated by channel numbers S1-01 through S1-08.
Addresses 1 to 127 may be assigned to each channel of LTB3.
Each loom ID for identification is determined by combining the serial communication channel
number and the LTB3 address. For example, the ID of the loom with 1 as its LTB3 address con-
nected to communication port channel 1 is indicated as “S1-01. 001”.
•
Determine the connection route for each channel to restrict the number of looms to about 100
(127 max.).
•
If the total number of looms exceeds 800, use two TMS scanner PCs (master and sub) for con-
nection. (The ID of each loom connected to the sub TMS scanner PC becomes S2-

•
It is also possible to use two TMS scanner PCs (master and sub) for easier cable routing.
•
The total of JAT710 looms connected directly to the TMS and other looms like JAT610 connected
via TMS scanner PCs must not exceed 1,000.
•
Use special-purpose communication cables that can be supplied from us.
•
Use conductive metal conduits for passing communication cables. In the neighborhood of the
power cable, use a separate conduit line and provide a minimum distance of 0.5 meter (for pro-
tection from noise). Communication cable conduits may be installed either underground or over-
head. Select whichever one according to the situation in the customer’s plant.
Connection cable between loom and computer (First lay the material cable,
and connect both ends via exclusive connectors later.)
