MANU3610-01
For RS485 Communication applications, ATS
recommends using a
round
data transmission cable that adheres to
the following specifications:
Five conductor shielded 24-gage wire with a drain.
The impedance of the cable should be 100 Ohms.
The capacitance should be 12 pico-farads per foot.
The jacket of the cable is typically PVC material.
Note
: If the host is not equipped with an RS485 port, an ATS
RS232/485 Converter with a 12-volt power pack
assembly will convert the terminal communication lines to RS232 levels. The host output of the RS232/485
Converter plugs directly into the ATS
RS232 Communication Adapter.
RS485 allows for the Series 3610 to be used in multi-dropped networks. Thirty-two (32) terminals can be
supported on a single host communication port. The use of ATS
Series 1000 Network Controllers allows up to
five hundred and twelve (512) terminals on a single host communication port.
