Serial Interface
The HM8115-2 is well equipped for use in automated test
systems. An optcoupler-isolated RS-232 interface is standard.
Interface parameters
N, 8, 1, Xon-Xoff:
(No parity bit, 8 data bits, 1 stop bit, Xon-Xoff.
A terminal program like HyperTerminal may be used for data
transmission. After performing all settings in the terminal pro-
gram press the ENTER key once prior to sending the first
command to the HM8115-2
Baud rate
1200 or 9600 baud.
Changing interface parameters
Only the baud rate can be selected as either 1200 or 9600 baud.
In order to do this proceed as follows:
-
Turn off the HM8115-2.
-
Turn the instrument back on.
-
Press the lefthand FUNCTION pushbutton
-
Press the lefthand pushbutton
until the LED "WATT" lights up.
This new baud rate will be stored permanently unless changed.

Made in Germany
The RS-232 interface connector is located on the rear panel
(9pin submin D). The interface allows the transmission of data
from the instrument and its remote control.
For the connection between the HM8115-2 and a
PC (COM port) any standard cable with 9pin submin D on both
sides may be used, provided it is shielded and < 3 m.
If a PC has a 25pin connector an adapter 25 to 9pin
has to be inserted, only 3 wires are used.
