[1] Make sure that the slave station number set in "USER.PAR" (User
parameter) coincides with the station number setting of the TR48DIOC
module.
[2] When the TR48DIOC module or modules are connected, set ON the
terminator setting switch equipped on the TR48DIOC module which is located
on the extreme right side in terms of cable wiring when seen from the
controller front side.
The switches (2 pins) provided on the front upper side of the TR48DIOC
module represent pin 1 (upper) for slave station number setting and pin 2
(lower) for terminator setting.

The slave station setting is already described above. Specify the slave station of
TR48DIOC to be used, according to the station number set in "USER. PAR" (User
parameter).
For the terminator, when only one (1) TR48DIOC module is used, set ON the
terminator setting switch equipped on the module.
When two (2) TR48DIOC modules are used, see Fig. 7.3 for example. As the
TR48DIOC module on the extreme right side as viewed from the controller front
side is the terminal station in terms of cable wiring, set ON the terminator setting
switch equipped on this module alone. The terminator of the left TR48DIOC
module should remain OFF.
Be sure to execute Items [1] and [2] above. Otherwise, the system does not
function normally and go wrong.
With the above setting, make sure that both the POWER and RUN LEDs on each
TR48DIOC module are illuminated.
Turn on the power to the robot while the power to TR48DIOCN/TR48DIOC module
is on. An error occurs depending on the power-on timing.
