7.2  External I/O Communication 
  If the number of digital I/Os is insufficient for the system, up to two (2) 
TR48DIOCN/TR48DIOC modules [option; twenty-eight (28) inputs and twenty (20) 
outputs] can be connected as the I/O function extension unit.    When the 
TSL3000E/TSL3100E robot controller is assigned to the master station and the 
TR48DIOCN/TR48DIOC module to the slave station, inputs and outputs can be 
controlled via the RS485 serial communication. 
In addition to the TR48DIOCN/TR48DIOC module, a distribution I/O module 
designated by Toshiba Machine, which can serve as the slave station, can be used 
also.
