SERIAL (RS232 CONTROL)
The DSMC2 REDVOLT Expander features a SERIAL connector. The 7-pin 0B LEMO SERIAL connector supports
RS232 RX, RS232 TX, and a General Purpose Input (GPI) trigger (active-low switch closure). The connector also offers
auxiliary power out, with a maximum sustained current draw of 1.5A.
To operate the GPI contact closure style trigger, short Pin 7 (GPI) to Pin 6 (ground).
The SERIAL connector was designed to support 6-pin 0B cables used with the RED Tactical Hand Controller (T.H.C.).
Although the connectors on those cables do not have pin 7 (GPI), the other 6 pins do match pins 1 to 6 on the SERIAL
connector.
