20 mA Current Loop (C-Box 100 w/INT-30 Accessory Only)
To adapt DS4600A to 20 mA current loop interfaces, it must be connected to a
C-BOX 100 equipped with an INT-30 (20 mA current loop adapter accessory board).
The INT-30 converts RS232 communication on the scanner into 20 mA current loop
signals to the host. See the C-BOX 100 Installation Manual and the INT-30
instructions.

Auxiliary RS232 Interface
The auxiliary serial interface is used exclusively for RS232 point-to-point
connections.
The parameters relative to the auxiliary interface (baud rate, data bits, etc.) as well as
particular communication modes such as Local Echo can be defined using the
WinHost utility program or Host Mode programming. For more details refer to
paragraph 2.6 and to the section "Auxiliary Interface Menu" in the WinHost Help On
Line.
The following pins of the 25-pin connector are used to connect the RS232 auxiliary
interface:

When the auxiliary interface is permanently connected as part of the system cabling,
it is recommended to connect the cable shield to earth ground.
