Chapter 2
Communication Wiring
We recommend that shielded-twisted-pair cables that comply with the EIA
RS-485 standard be used with the ADAM network to reduce interference.
Only one set of twisted-pair cables is required to transmit both Data and
RTS signals. We advice that the following standard colors (as indicated on
the modules) be used for the communication lines:
DATA+ (Y) Yellow
DATA- (G) Green
ADAM Utility Software
A menu-driven utility program is provided for ADAM module configura-
tion, monitoring and calibration. It also includes a terminal emulation
program that lets you easily communicate through the ADAM command
set. (See Appendix D, Utility Software)
ADAM Communication Speed
In ADAM series, the baudrate can be configured from 1200 bps to 38.4
Kbps. And the baudrate of all modules in an RS-485 network must be the
same.
ADAM Isolated RS-232/RS485 Converter (optional)
When the host computer or terminal has only a RS-232 port, an ADAM
Isolated RS-232/RS-485 Converter, connected to the host’s RS-232 port, is
required. Since this module is not addressable by the host, the baud rate
must be set using a switch inside the module. The factory default setting is
9600 baud.
ADAM Repeater (optional)
When communication lines exceed 4000 ft (1200 meter) or the number of
ADAM modules connected is more than 32, a repeater should be connect-
ed to expand the first segment. Up to 8 Repeater modules can be connected
allowing connection of up to 256 ADAM modules. As with the Converter
module, the Repeater module is not addressable by the host and the baud
rate must be set by changing the switch inside the module. The factory
default setting is 9600 baud.
