IMPORTANT: Before you proceed with cabling, you must know
whether the devices to which you will connect the Model 24SII DES
are DTE (Data Terminal Equipment) or DCE (Data Communication
Equipment). The following devices are generally DTE: terminals,
printers, computers like the IBM PC. The following devices are DCE:
modems and some computers.
If your device transmits data on Pin 2 or receives data on Pin 3, it is
DTE. If your device receives data on Pin 2 and transmits data on Pin
3, it is DCE. However, to verify the interface requirements, please
refer to the Owner's Manual for your device.
The serial ports on the M24SII-V04 I/O module has DB-25 female
DCE connectors and use the following signals for communication:
