Connecting RS-232 Devices
When an IMC-S/23x serial port is configured for RS-232 operation (see
Configuring the IMC-S/23x earlier in this section), RS-232C
compatible serial communications devices may be connected to it using
readily-available RS-232C cables. To prevent damage to the
IMC-S/23x or the serial device, make sure that the serial port is
configured for RS-232 operation before connecting RS-232 compatible
devices.
The pinout of each serial port is identical and shown for reference in
the table below.
Note that the hardware handshaking signals (RTS/CTS and DSR/DTR)
for both serial ports are jumpered inside the IMC-S/23x. This allows
the use of standard RS-232C cables with serial devices which require
hardware handshaking.
!
ATTENTION: Configure the serial port for RS-232
operation before connecting RS-232 compatible devices.
