(single-step mode)
Connect here to download data to all three programmable

programmable rail module only (single-step mode)
Optional serial ports may be used to

Downloading database files over the network
A CPU module’s Network A port and its modular phone jack
share an interrupt with the module’s microprocessor. As such,
the microprocessor disables the Network A port whenever you
connect the SDU computer to the modular phone jack.
Consequently, download options differ for Class A and Class B
networks.
