CBX CONNECTION BOX INITIAL CONFIGURATION
PRODUCT REFERENCE GUIDE

Inside the Tachometer is a switch that needs to be set to accommodate the settings of
your application. The switch allows you to set the type of wiring and the pulses per rev-
olution. For a typical system the pulses per revolution may be set to 192 or 240. In this
example we are wired for PNP communications. The switch settings are shown below.
Serial Communication Wiring to CBX510
The SC5100 provides serial RS232/RS422 communications to other devices through the
CBX510. Each 25 pole DSUB port provides connection for RS232/RS422 communica-
tions.
• RS232 provides point-to-point communications at distances up to 15 M [50 ft].
• RS422 provides point-to-point communications at distances up to 1200 M [3940
ft]
• Auxiliary serial provides an alternate RS232 connection which can be used for con-
necting a hand held scanning device.
The following wiring diagrams illustrate the different types of serial communications
available via the CBX510 terminal block. It is very important that you make the proper
pin connections.
RS232 with or without 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.
