VCX-4402-E Installation and Operating Instructions
Page 5
Com Port Data Interface
There are two bi-directional data interfaces, RS-232 and RS-422 selectable, on the encoder and
decoder assemblies. Each interface uses RJ-45 connectors. Refer to Table below for the correct pin out.
When using the RS-232 configuration pin 7 is ground. Com Port parameters are configured through the
system software.
Refer to Appendix A for the correct pin out.
Video Input Interface
Connect a BNC-terminated coaxial cable from a composite video source (e.g., CCTV camera) to
the BNC connector labeled “VIDEO IN” (encoder). The composite video input should be in NTSC or
PAL format. The maximum length of cable that should be interfaced to the encoder or decoder is 100 feet,
although the specific installation environment will dictate the actual permissible length.
Ethernet Interface
There is one Ethernet interface for encoder or decoder, which uses a standard RJ-45 connector.
The standard method of terminating an ETHERNET cable reflects the TIA568A standard
(Telecommunications Industry Association standard).
Refer to Appendix A for the Straight Through and Crossover Ethernet Pin Out.
Power
Power is applied through a standard IEC type detachable line cord at the rear of the unit. The unit
automatically senses 110 VAC or 220 VAC supply and will operate with either. The typical current is 1.2
amps from a 110VAC line and drops to .9 amps from a 230 VAC line source.
Display (full size encoder only)
The fluorescent LED display (Full Width 19” Encoder only) provides a scrolling list of key
parameters when the unit is in its active (non-stand-by) state.
The display is a two-line display. Each parameter is displayed, in turn, for three seconds
on the bottom line. It then moves to the top line while the next parameter is displayed on the
bottom line.
The parameters displayed are as follows:
Name of unit
