connecting to a Host computer
There are 3 ways to connect the TTDM-128 to a host computer:
hard-wired RS-232, hard-wired RS-485, or standard modular RS-
232 cable. For permanent installations, the hard-wired method is
Make connections.
• Confirm that power to the unit has been shut off.
• Open the enclosure door.
• Feed the end of the communication cable through the gland
plate br adapter/bushing into the enclosure.
• Remove the J13 cable plug cm from the socket.
For RS-232 connection:
• Connect the RX, TX, RTS, CTS and DGND wire to terminals 5, 6,
7, 8 and 10 respectively.
• Set the host port selector switch cq on the User Interface
board 7 to the RS232 position.
For RS-485 connection:
• Connect the positive wire to terminal 5 (RX/A) and the negative
wire to terminal 6 (TX/B).
Set the host port selector switch cq on the User Interface
board 7 to the RS485 position.
• Connect the shield wire to the grounding lug bq.
• Insert the J13 cable plug back into the socket cm.
Start-Up and System Testing
power up the system.
After connections are complete, supply power to the unit. The unit
will go through a series of self-tests, and then display the system
status. If the sensing circuit is complete and free of leaks or other
problems, only the green Monitoring LED will illuminate, and the
LCD display will appear similar to that shown at right:
If this is not the case, you can find additional information in the
TTDM-128 Operation and Maintenance Manual (H56853) supplied
with the module.
commissioning
Your system should be commissioned by an authorized TraceTek
representative. The system map is a crucial part of a TraceTek
locating system. The TTDM-128 will give the point along the sens-
ing cable at which liquid has been detected; the map is essential
to show its physical location.
