ADAM-5510/P31 5-7
Chapter 5
Ø LED indicators :
Check the ‘COMM’ LED on the ADAM-5510/P31 front panel. If the
COMM LED is blinking, the program ADAM_P31.COM is running and
is searching for the Com Port on the ADAM-5510/P31 which will
receive commands from Paradym-31 on the host computer. If a com-
mand enters COM1 (RS-232 ), the ‘COMM’ LED will be dark unless
communication between ADAM-5510/P31 and Paradym-31 is in
progress. If a command enters COM2 ( RS-485 ) the ‘COMM’ LED will
remain lit.
Step 2 : Cable connections
Ø COM1 ( RS-232 ) : cross over
If you use COM1 to communicate between the ADAM-5510/P31 and
Paradym-31 on the host computer, the cable wires must connect
between the computer port and the ADAM-5510/P31 port as shown::
Pin-2 ( Rx ) Pin-3 ( Tx )
Paradym-31 Pin-3 ( Tx ) Pin-2 ( Rx ) ADAM-5510/P31
Pin-5 (Gnd) Pin-5 (Gnd)
Of course, you can use a Null Modem Cable to connect the ADAM-
5510/P31 and host computer (Paradym-31) directly via the RS-232
interface.
Ø COM2 ( RS-485 ) :
If you adopt this connection scheme:
(host computer (Paradym-31) ADAM-4520 ADAM-
5510/P31 ), you must check the baud rate and data length on the
ADAM-4520. Please open the ADAM-4520 plastic shell and set the
proper baud rate. Set the data length to 10.
