DTAM Micro Operator Interface 12
To connect the DTAM Micro terminal to an RS-485 device:
1. Make sure that the power to the DTAM Micro is off.
2. Use the proper cabling to connect the DTAM Micro
communications port to the port of the controller (PLC-5 channel
0 or SLC 5/03, 5/04 or 5/05 RS-232 port).
•
Use cable, Catalog No 2707-NC4 for PLC-5 channel 0
RS-422 connection
•
Use cable, Catalog No. 2707-NC5 for PLC 5 channel 0
RS-232 connection. The 2707-NC5 cable converts the signals
from the RS-485 port to RS-232 levels.
•
Use cable, Catalog No. 2707-NC1 for SLC 5/03, 5/04 or 5/05
port and DH-485 network connections
If you need to make your own cable, refer to the connection
diagrams in Appendix B of the DTAM Micro User Manual
(2707-803). The maximum recommended cable length is 200
feet (60.8 meters).
Important: The DH-485 network cable requires proper
shielding, grounding, and termination. Refer to Data Highway /
Data Highway Plus / Data Highway-485 Cable Installation
Manual (1770-6.2.2).
3. The DH-485 connectors are not electrically isolated. If electrical
isolation is required, use Link Couplers (Catalog No. 1747-AIC).
!
ATTENTION: Electrical isolation using Link Couplers (Catalog
No. 1747-AIC) is required in applications where the distance
between the DTAM Micro terminal and the SLC is greater than
6.5 feet (2 meters).
4. Make sure that the communication parameters of the DTAM
Micro terminal match the host device.
5. Apply power and verify that communications are established.
