Interfacing via the RS232 Output
The Model 440 can transmit data in RS232C Serial format to
compatible devices such as Serial Printers and computers. There
is no handshake capability but data can be received and
manipulated by most data acquisition software packages.
The cable required for connection to IBM compatible computers
is part number 477758 and can be ordered from your distributor.
The pin configuration of that connector and Model 440 output
protocols are as follows:
Pin
Signal
1
device enable (link to pin 5)
2
RS232 Tx (signal transmit)
3
not used
4
not used
5
protective ground (0V)
6 - 9
not used
DATA
socket
To enable the RS232 a link is required between pin 1 (device
enable) and pin 5 (protective ground).
