NOTE: Only pins 2, 3, & 7 are required for serial interface to one controller.
The Isco D Series syringe pump controller may include an
optional USB interface. The USB connections are located on the
pump controller rear panel labeled USB/Ethernet. The connector
pin usage is outlined in Table 8-2. Use optional cable
(PN-60-1244-487) to connect the USB to the 25 pin connector
labeled USB/Ethernet. The drivers for the USB can be down-
loaded from http://www.isco.com/support/updates.asp
Connecting devices to energized circuits may cause
personal injury or property damage. Power must be
removed from the pump before connecting external
devices.

The cabling scheme for your system will depend on the number of
instruments you need to control. The computer is always con-
nected from the serial port to the serial port(s) of the D Series
controller(s) it is controlling. Each controller is connected to its
pumps in the normal fashion, i.e. the pump control cables are
attached to the pump A, B, and C connectors on the rear panel of
the pump controller. The cable you select to connect to your
network will depend on the type of serial port your computer has
and the number of controllers you wish to connect.
Network communications are initiated by your computer.
To connect one controller, use a null-modem cable (available from
Teledyne Isco, part #480-7996-00) to connect the 9-pin serial
output port of the computer to the RS-232-C port on the rear of
the controller, as shown in Figure 8-1.
