To set up the RS-232 terminal
(if not using 3rd party software)
use the following steps:
1. Connect the HD-SC-500 to a PC using a DB9 to DB9 and DB9 to USB cable
Note:
A gender changer and/or null modem may be needed between some connections
a. Remove the DB9 connector, strip and connect the wires to the included captive screw
connector
(as explained above)
, then connect the captive screw connector to the matrix
2. Go to the Device Manager folder
(see picture A)
3. Find the HD-SC-500 COM port and right click with a mouse and select properties
(see picture B)
Note:
If unsure which COM port is the HD-SC-500, unplug the cable and plug it back in. It will disappear and
reappear on the COM port list.
4. Under the properties menu select the port settings tab and update the menu to the
HD-SC-500
default settings of
: Bits Per Second: 115200, Data Bits: 8, Parity: None, Stop Bits: 1 and

connector. The pins have functions associated with them, some
will are unassigned.
Note:
Typical DB9 connectors use pin 2 for TX, pin 3 for RX, and pin 5
for ground. On some devices functions of pins 2 and 3 are
reversed.
