4.1.3 Serial Communication
RS-232 protocol at at a default baud rate of 19,200 bps and is capable of standard baud rates from 9600 to
115,200 bps. Furthermore the LK204-7T-1U is also capable of reproducing any non-standard baud rate in
between using values entered into our baud rate generation algorithm and set through command 164 (0xA4).
The display module communicates at standard voltage levels of -30V to +30V or at TTL levels of 0 to +5V
by setting the Protocol Select Jumpers to TTL.
4.1.4 USB Communication
capable of communicating via a USB interface. The USB communications are identical to the serial commu-
nications. Communication is via a virtual com port, which is created in the operating system by the drivers
necessary to install the USB display. The LK204-7T-1U communicating via USB is capable of baud rates of
19,200 bps to 115,200 bps. Other baud rates are subject to the limitation of the virtual com port driver. For
further information regarding supported operating systems, and driver limitations please contact technical
support.
