2Firmware Licensing Terms
2.1 Firmware with Open Source GPL
The Z-PASS firmware contains Open Source software under GPL. According to Section 3b of GPL, we offer you the
source code. You can obtain the source code with licensing terms of the Open Source software from Seneca s.r.l. on
request. Send your request to [e-mail] with the subject "Open Source Z-PASS ".
3Features
The Z-PASS1 and Z-PASS2 devices are “Ethernet to Serial Gateways”(also known as “Serial Device Servers”) with
three main operating modes:
Modbus Bridge
Transparent Bridge (Remote Serial COM, Serial Tunneling)
Modbus Gateway
Both devices provide the following features:
VPN connectivity
full configuration by an integrated web site
FW upgrade, that can be performed locally, by a USB pen, or remotely, by means of the web site
The main difference between the two devices is that Z-PASS2 integrates a 3G HSPA modem, while Z-PASS1 can be
connected to an external 3G (UMTS/HSPA) modem (Seneca Z-MODEM-3G
1
). Actually, Z-PASS1 is aimed at applications
where an Internet connection is already available, while Z-PASS2 provides connectivity by itself.
Z-PASS2 and Z-PASS1 (when connected to an external modem) can be used as a Router, routing packets between the
WAN (Mobile Network) and the LAN (Ethernet).
Both devices are based on a 32bits ARM9 processor, equipped with the Linux operating system (Linux kernel 2.6.28).

Z-PASS1-R01 and Z-PASS2-R01 are new versions of the Z-PASS1 and Z-PASS2 products, providing the following new
features:
the two available Ethernet ports can be configured as two fully separated network interfaces (“LAN” and
“WAN”), whereas in the older versions they could only work as ports of an Ethernet switch; the user can
choose if the two ports shall work in “LAN/WAN” mode or “Switch” mode, by means of a new configuration
parameter (“Ethernet Mode”);
there are 4 more LEDs, providing information about the “Ethernet Mode” and the VPN functionalities.
Z-PASS2-IO is a new version of the Z-PASS2 product, providing the following new features:
one digital input which can be used to disable remote connection to the device
one digital output which goes HIGH when the device is remotely accessed
one digital input which can also be used as a local alarm
one digital output which can also be used as a remote command
two configurable digital inputs/outputs
a new set of LEDs
COM1 RS232/RS485 mode set by software (configuration parameter), instead of HW DIP switch

or by Z-PC-DINAL1-35 accessory for Z-PASS1, Z-PC-DINAL2-52.5-17 for Z-PASS2. The following picture shows the
meaning of the IDC10 connector pins.
Power supply is available only from the rear connector for Z-PASS1/ZPASS1-R01, while:
Z-PASS1-IO can be powered also through 17-18 screw terminals;
Z-PASS2/ZPASS2-R01/ZPASS2-IO can be powered also through 14-15 screw terminals.
If Z-PC-DINAL1-35 or Z-PC-DINAL2-52.5-17 accessory is used, the power supply signals and communication signals may
be provided by the terminals block into the DIN rail support. In the following figure the meaning and the position of
the terminal blocks are shown.
GNDSHLD: Shield to protect the connection cables against interference (recommended).
The Z-PASS has two RS 485 serial ports for Modbus communication: COM 2 and COM 4. The RS485 connection for
COM 2 can be set up by means of the corresponding screw terminals or by the IDC10 connector.

USER MANUAL –Z-PASS1/Z-PASS2
12
Through a removable 4 pin connector, the Z-PASS provides a serial RS232 port or, as an alternative, a third RS485 port.
In order to select the RS232 port on the removable 4 pin connector, put the SW2 DIP-switch
2
on ON position; to select
the RS485 port on the removable 4 pin connector, put the SW2 DIP-switch on OFF position.
In Z-PASS1-IO/Z-PASS2-IO, the mode (RS485/RS232) of this port is set as a parameter in software configuration.
The cable length for the RS232 interface must be less than 3 meters.
2
While in Z-PASS1 the SW2 DIP-switch position can be changed by the user, in Z-PASS2 the DIP-switch is internal and
its position is permanently set in the factory.

The Z-PASS has a USB HOST type A connector, that can be used to connect an external USB memory; this is used for
FW upgrade (see chapter 6.4).
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-PASS to let it detect the USB device.
The Z-PASS1 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-PASS1-IO.
The Z-PASS has two Ethernet ports with RJ45 connectors on the front panel. The two ports are internally connected in
HUB/SWITCH mode. The two ports have the same MAC Address.

The Z-PASS has a plug-in connector for micro SD card placed in the side part of the case.
To insert the SD card into the connector, be sure that the SD card is oriented with metal contacts facing towards left
(with reference to the figure).
The SD card can be of any class.
The Z-PASS2 has a slot for SIM card, placed on the side of the case. Before pushing the SIM card into this slot, please
be sure that the SIM card golden contacts are facing towards right (please see the figure below).
