Com Port Data Interface
There is one bi-directional data interface, RS-232 and RS-422 selectable, on the encoder,
which uses a RJ-45 connector. Refer to Table below for the correct pin out. When using
the RS-232 configuration pin 4 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.
