2.5 Connecting RS232/RS485 Cables
With serial control, you can control one
TD61
or several
TD61
s at the same time.
Connect to the computer
Connect the TD61 to the serial out port of a com-
puter or another type of controller, such as a video
controller. Connect with twisted pair computer serial
cable, such as Cat-5, using straight-thru cable.
An RJ45-DB9 adapter is included in the accessory
kit. If you lose or need extras, you can convert the 9-
pin serial port to RJ45 with an adapter, which you can
buy in most electronic stores.
If you are connecting to more than one TD61, con-
nect from the computer or controller to the first
TD61. It doesn’t matter which unit this is.
Connect this first TD61’s RS485 Out to the next
unit’s RS485 In.
Start with RS232 and loop all the rest with RS485.
The last display in a group should not usually need
termination, however, if you are experiencing prob-
lems try terminating the last display by going to
MAIN
MENU
>
ADVANCED OPTIONS
>
SERIAL PORT SETTINGS
and
checking the
TERMINATE
RS485
box at the bottom of the
menu.
Wiring the adapter
To go from 9-pin D-sub serial connector on the back of
the ccomputer to an RJ45 connector, use a standard
RJ45-to-9-pin adapter. Wire it internally as shown. The
wiring shown for this adapter is correct for
straight-thru
cables. Straight-thru cables are wired 1-to-1, 2-to-2, etc
.
