The connector pin-out is given in the following table:
Pin RS232 RS485
1 (bottom) - -
2 Tx B
3 Rx A
4 (top) GND GND
The Device has a USB HOST type A connector, that can be used as an additional serial port (using a Seneca S117P1, for
example) or to connect an external USB memory; this is used for FW upgrade (see chapter 17).
Please note that, on this USB port, the “hotplug” feature is not available; so, after plugging the USB device, it is
necessary to power off/on the Z-TWS4/Z-PASS2-S to let it detect the USB device.
The Z-TWS4 also has a second USB HOST connector, with micro-USB plug-in, that can be used to connect a USB device
by means of a “Micro USB to USB” adapter; this port is no more available in Z-TWS4-IO.
