Rockwell Automation 1203 Serial Communications Module Series B - Manual (Page 30)

2–16 Installation
1203–5.5 September 1995
Cable Requirements
SCANport cables are available in either male–to–male or male–to–
female configuration. You can connect cables of up to 10 meters (33
feet) from the master to the SCANport device (A in the figure
below). If you use a Port Expander (as shown in the figure below),
you need to subtract the cable length from the master to the Port
Expander from the cable length used to connect the device to the
expander (B1 + C = a maximum of ten meters).
1305 Drive
An Allen-Bradley SCANport link cable is used to connect the Serial
Communications Module to the drive (as shown below).
