Interface Compatibility
• PS/2 Keyboard: Compatible with all standard keyboards. Certain
keyboards with enhanced features may also be supported with custom
firmware.
• PS/2 Mouse: Compatible with all standard 2-button, 3-button and wheel
mice. To connect to a PC that does not have a PS/2 mouse port, an active
serial converter is required - Model: Mdapt (PS/2).
• Audio: Input and output are line-level. Amplified speakers are required. A
microphone may be directly connected to the Remote Unit (optional pre-
amplification).
• Serial: Transparent up to 19.2K Baud (38.4K operation may be possible
with some devices). The following serial signals are extended: TX, RX,
RTS, CTS, DTR, DSR. In rare cases, a wiring adaptor may be required to
transfer RI and DCD.
• Video: VGA to UXGA. Separate sync, composite sync, or sync-on-green.
Maximum resolution and refresh rates depend on cable length and cable
type (see Appendix G: Specifications, page 48).
