4)
Regardless of DB-9 or DB-25, carefully short pins 2 and 3 together on the computer.
5)
Enter the following string of characters in the terminal window: 123123
6)
112233112233 should be displayed in the terminal window. If 123123 was displayed instead, it is
likely that the wrong serial port has been chosen. Go back to step 2.
7)
Now that the correct port has been located on the computer, remove the short from pins 2 and 3.
8)
Connect the cable to the back of the computer, but do not connect the other end to the GSD8 series
control. Instead, temporarily short pins 1 and 8 of the RJ-45 plug on the cable.
9)
Enter the following string of characters in the terminal window: 123123
10)
112233112233 should be displayed in the terminal window. If 123123 was displayed instead, it is
likely that either the cable is bad or pins 1 and 8 are not shorted correctly. Go back to step 8 and
test again.
11)
At this point, the computer is configured and cable is probably wired correctly. Remove the
temporary short and plug the cable into the drive’s modular jack.
12)
Type the following command into the terminal window (using all capital letters): AS01 (followed by
pressing the computer’s Enter key)
13)
The unit should respond with the actual speed, then the connection is complete and functional;
otherwise, it will be necessary to double-check the wiring and repeat some of the above tests.
NOTE: Many of the commercially available modular connectors cables you buy off the shelf will invert
the wires going between the two connectors on the ends of the cable. Improperly wiring the serial
ports will not damage the control or the communications peripheral but the communications will not
work. In case of difficulty,

computer dealer for assistance.

Software - Data Format
The GSDA-CM-8 uses a standard serial interface protocol found on most computers, process
controllers, terminals, etc. The format for data is as follows:
Start Bits
1
Data Bits
8
Stop Bits
1
Parity
None
Duplex
Half (no echo)
Baud Rate
Selectable (see below)
To avoid confusion, we suggest that you do not program two items that are involved with
communications through the serial port. The items are as follows:
Item 20:
Network Address. This can be a value from 01 to 99. If you have more than one GSDA-CM-8 on your
network, you should set each unit to a unique address. Commands sent to address “00” will be acted
upon by every GSDA-CM-8 on your network. This can be helpful, for example, to do an “All Stop”
command.
Item 21:
Baud Rate. This can be a value from 1 to 8. A table showing the baud rates for the possible values
of this item is shown below:
