WARNINGS

• Do not apply any voltage other than the speciﬁed voltage.

• Do not apply voltage to the DB-9 connector AND power connec-

tor.

• Do not apply more than +5VDC to pin #9 on the DB-9 connector

if module is designated “standard voltage”. If the module is des-

ignated “wide or extended voltage”, then you may apply between

8-15 Volts accordingly. Please see the ﬁgures below for power

connections and appropriate solder jump required.

Figure 8: RS-232 and Power Connections

Figure 9: Power Applied via DB9 Connector

The RS-232 connector on the PC cable is wired so that a standard ‘straight through’ 9 pin D-sub cable

may be used to connect the module to a standard serial port such as COM ports on PCs.

NOTE This device complies with the EIA232 standard in that it uses signal levels from

+/- 3V to +/- 12V. It will not operate correctly at TTL (0 to +5V) levels with out modiﬁca-

tion. A null modem cable will not work. Please see ﬁgure below for pin out conﬁguration.
