The RS232 balance port is a female port whereas the RS232 printer port is a male port.
The 6400 Calorimeter is also equipped with an RJ45 Ethernet port for connection to a
computer. Before making any of these connections, the data transmission rate of the
Calorimeter and the printer, balance or computer must be matched. Generally the baud
rates on either device can be changed to achieve this match.
The 6400 will also allow the user to specify the IP addresses of one or more Balance
Interface devices on the network by selecting the Network Data Device menu in the
Communications Controls menu. Balance Interface devices are polled from device 1 to
15 for sample and / or spike weights when the weight entry mode is set to Network.
