RS-232 Serial Communications Cable, Model
2010D
to PC
A null modem cable is required when connecting the Model
2010D
to
a personal computer for downloading software updates, remote
control or other applications. The cable should be equipped with
a 9 pin female D connector on the Model
2010D
serial
communication port end for COM1 or COM2 and a 9 pin female D
connector or 25 pin female D connector on the PC end. The pin
outs for the null modem cable are given in Table 4-6. Note that
the Pin 1 (CD) and Pin 6 (DSR) are tied together on each end of
the cable since some terminal programs require the CD line to be
pulled high.
