8. RS-232 Communications
The SP2200 Syringe Pump can communicate with any computer, software package,
or device with an RS-232 communications port.
8.1 Connection and Networking
On the side of the pump are 2 square RJ-11 (“phone jack” style) sockets. Connect the RS-232
cable into the socket labeled “Computer”. Connect the other end to the serial port on the computer, or other
control device. Turn power off to the pump and the computer before connecting cables.
If the pump is part of a pump network, connect a pump network cable between the socket labeled “Pump
Network”, on the first pump, and the socket labeled “Computer” on the next pump in the network. Repeat for
each pump in the network, connecting the “Pump Network” socket of one pump to the “Computer” socket on
the next pump in the network. Up to 100 SP2200 pumps can be network together, along with other pumps
from the NE-1000 family of pumps, to one communications port on a computer. See section 9, “Logic
Interface: TTL Input and Output”, for a diagram of the pump’s connectors. When communicating with a
pump in a multi-pump network, each preceding pump in the network must be powered on.
Note on USB: If an RS-232 port is not available on your PC, the pump may be operated through a USB to RS-
232 converter cable (available as an accessory, part #CBL-USB232). This cable attaches to the standard RS-
232 to PC cable (part #CBL-PC-PUMP-7). The PC will create a virtual RS-232 communications port that
communicates through the USB to RS-232 converter cable. The terminal emulator can communicate through
this virtual port
Each pump in the network needs a unique network address to identify the pump to the computer. Network
addresses are from 00 to 99. If the network consists of only 1 pump, set the pump’s address to 0, the factory
default address. Also, each pump needs to be set to the same baud rate as the computer. The default baud rate
is 19,200.
8.2 RS-232 Pump Network Configuration
If only one pump is being used, leave the address at the default of 0.
Up to 100 pumps from the NE-1000 family of pumps can be attached to a computer in a single pump network.
