8. RS-232 Communications
The NE-500/NE-501 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 NE-500/NE-501 pumps can be network together, along with other
pumps from the NE-1000 series 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 series of pumps can be attached to a computer in a single pump network.
The network address is set using the command “*ADR nn", where "nn" is the pump's network address from 0
to 99. If only one pump is in the network, leave the address at the default address of 0. This will simplify
communications because the address can be left off the commands sent to the pump.
To set the network address, individually attach each pump to the computer. Disconnect the network cable from
the "Network" connector on the pump. Using the "*ADR nn" command, send a unique address to each pump
from 0 to 99. This operation only has to be performed once. The set address will be stored in the pump's non-
volatile memory and will take effect immediately. Once the set address command is sent, the pump will only
respond to commands sent to the set address.
To query a pump's current network address, send the command "*ADR" without any parameters. The pump
will respond with its current pump address in the response packet's data field.
