Calculation of current consumed by units <GT16/15>
When using multiple units, a barcode reader, and a RFID controller, the total current consumed by the
units, barcode reader and RFID controller must be less than the current that can be supplied by the GOT.
Design the system using the following values so that the total current is within the range of the current
supply capacity of the GOT.
(1) Current that can be supplied by the GOT (2) Current used by units, barcode reader and RFID controller

*1 : This value is used for calculating the current consumption of multi-channel functions.
For the specifications of each unit, see the manual supplied with each unit.
*2 : When using a barcode reader or a RFID controller to which the power is supplied
from the standard interface, add the current to be used by the barcode reader and
RFID controller at 5VDC. (Maximum less than 0.3A)
Extension unit interface 1
Extension unit interface 2
Up to 3 communication units and optional units can be mounted on
each extension unit interface.
Mount a unit that occupies two slots on the first stage.
However, when any of the following units are used, mount the unit on the
first stage, then mount other units on the second and subsequent stages.
For GT16 (Only one of these units can be mounted on the GT16)
GT16M-V4, GT16M-R2, GT16-V4R1, GT16-ROUT, GT16M-MMR
For GT15 (Only one of these units can be mounted on the GT1585V
and GT1575V)
GT15V-75V4, GT15V-75R1, GT15V-75V4R1, GT15V-75ROUT
The following units must not be stacked on other units. Mount any of them on the first stage.
GT15-75QBUSL, GT15-75QBUS2L, GT15-75ABUSL, GT15-75ABUS2L
GT15-75J71LP23-Z, GT15-75J71BR13-Z, GT15-75J61BT13-Z

Instructions for mounting and removing the GT15-CFCD
An extension unit cannot be mounted on a CF card unit.
When extension units are mounted, mount the CF card unit on the last stage.
When mounting a CF card unit on the extension interface 1 (left), ensure
that the number of extension units mounted on the extension interface 2
(right) is smaller than the number on the extension interface 1 (left).
Otherwise, the CF card cannot be inserted or removed.
Remove the CF card unit in the designated direction ( PULL) to prevent
damage to the connector.
Standard interface (built-in RS-232 interface)
The interface can establish a serial connection with connected
devices and peripheral devices, such as a barcode reader.
Standard interface (built-in Ethernet interface) (GT16 only)
The interface can establish a connection with connected devices via Ethernet.
Standard interface (built-in RS-422/485 interface) (GT16 only)
The interface can establish a serial connection with connected devices.
