• RS-232, Up to 19.2K baud
• Address selectable (1–90)
• Connect to DirectSOFT, D2–HPP,
DV-1000, HMI, or DirectNET master
• 8 data bits, one start, one stop
• Asynchronous, Half–duplex, DTE
• Odd or no parity
Port 2 Specifications
Port 2 on the DL250-1 and DL260 CPUs is located on the 15-pin D-shell connector. It is
configurable using AUX functions on a programming device. This applies to the DL250 as
well.

Remote I/O, (ASCII IN/OUT DL260 only)
• RS-232, non-isolated, distance within 15 m
(approx. 50 feet)
• RS-422, non-isolated, distance within
1000 m
• RS-485, non–isolated, distance within
1000m (DL260 only)
• Up to 38.4K baud
• Address selectable (1–90)
• Connects to DirectSOFT, D2–HPP, operator
interfaces, any DirectNET or Modbus
master/slave, (ASCII devices-DL260 only)
• 8 data bits, one start, one stop
• Asynchronous, Half–duplex, DTE Remote
I/O
• Odd/even/none parity
