Ke24 I/O Data To Serial Port - Hagstrom KE24 User Manual

PC Keyboard to Serial Port (ASCII)
The KE24 may be programmed to send data from the PC keyboard
to the KE24 serial port in ASCII representation.
If programmed to send the key data from the PC keyboard in
ASCII, the corresponding ASCII code is transmitted by the KE24
for each press of a key. If a "break" code is selected to be sent
when the key is released, the same ASCII code is preceded by a
hex "F0".

KE24 I/O Data to Serial Port

The KE24 may be programmed to send data from keypads or
switches connected to the I/O header. When detected, the user
programmed code is transmitted when the input is "made."
In addition to the "make" code for the input, the KE24 may be
programmed in this mode to send a "break" code when the key
is released. If selected, a "break" code consisting of "F0" hex
preceding the "make" code for that key is transmitted when the
input is released.
Use the KE24Load configuration program to specify the codes to
be transmitted for the various key positions. The serial characters
are always 8 bit, no Parity, and 1 stop bit. The Baud rate may be
programmed in increments from 300 to 19200 baud.
Note: When using the KE24 in modes where no connection to
a PC is required (keyboard to RS-232 or I/O header to RS-232),
you must supply 5 Volts to the unit. Refer to Appendix B for details
of this connection.
