3.10.5 Serial Communication Wiring to CBX100/CBX500
The AV7000 provides serial RS232/422 communications to other devices through the
CBX100.
ï‚· RS232 provides point-to-point communications at distances up to 15 M [50 ft].
ï‚· RS422 provides point-to-point communications at distances up to 1200 M [3940 ft]
The following wiring diagrams illustrate the different types of serial communications available
via the CBX100 pin block. It is very important that you make the proper pin connections.
RS232 with No Handshaking
Use RS232 for a direct connection to a controller, personal computer, or other device. RS232
provides point-to-point communications at distances up to 15 M [50 ft]. If longer cable lengths
are needed, use RS422.
Use the following illustration as a guide when you want to connect your system to a device
using RS232 communication with no handshaking.
