1. Summary
ZLAN5443A is new generation of 4 ports serial device server developed by Shanghai
ZLAN. Compared with ZLAN5400A, ZLAN5443A is more cost-effective as it use the third
generation hardware technology, and ZLAN5443A support Modbus TCP to Modbus RTU
Gateway function. Modbus Gateway support multi Modbus clients connecting and read
data at the same time, as “multi-host” function.
ZLAN5442A support 4 RS232 serial ports, 4 RS422/485 ports, realize 4 ports
simultaneous full-duplex working by connecting to ZLAN5443A via a cable. It’s the ideal
choice of multi-serial ports networking.
ZLAN5443A support extending to 8/12/16 ports through cascade Ethernet port, up to 32
serial ports.

Feature:
1) The 4 serial ports all support 3 serial forms: RS232, RS485, RS422.
2) The 4 serial ports can independently full-duplex working, no interference between
each other.
3) Support extension function, can extending up to 32 serial ports.
4) Rich signal lights, each port has self TCP connecting indicator and data activity
indicator.
5) Support power supply via cable ----POE power supply

Figure 3 ZLAN5443A Front View
1) Size: L x W x H =9.2cm×19.7cm×2.5cm
2) Power supply: the standard power adaptor (5.5mm inner core is positive) or power
binding post can be used. The power supply voltage can be 9 ~ 24V and the power
requirement is greater than 5W.
3) Ethernet Port:
a) Normal Ethernet Port: the user connects ZLAN5443A to the switch, hub, or
directly to the computer network card.
b) Cascade Ethernet Port: for cascade of ZLAN5443A, refer to the description of
the cascade part in this document.
c) POE power supply: pin 5 (GND) and pin 8 (VCC) of the normal RJ45 Ethernet
port can be used to supplypower to ZLAN5443A, and the power supply voltage is
between 9 ~ 24V. RJ45 network line sequence refers to figure 4.

4) Indicator:
a) Data forwarding indicator ACT: ACT light indicates that data is normally
transmitted between Ethernet and corresponding serial port, without data
communication, ACT light is not bright.
b) TCP connection establishing indicator LINK: LINK light indicates that the
current TCP connection of serial port is established, and the data can be sent and
received normally.
c) Power indicator PWR: indicates that the serial port server has already been
charged.
d) Network indicator NET: indicates that the network line has been connected.
5) Serial port:
a) 485/422 serial port: when used as 485, only 2 lines are connected to it, and 4
wires should be connected when used as 422. The line sequence is shown in FIG.

5. Usage
ZLVircom is installed to manage the device.
Charging to ZLAN5443A, network wire connects to the normal Ethernet port of
ZLAN5443A. Then using the “Device Manage” of ZLVircom software can see the interface
shown in FIG. 5.

The 4 lines in this line correspond to the four serial ports in ZLAN5443A, and the
corresponding IP address of ZLAN5443A is 192.168.1.200 ~ 192.168.1.203 in factory
setting. The usage of a single serial port please refers to the <User Guide of Networking
Products> file http://www.zlmcu.com/download/serial_server_user_manual.pdf.
6. Modbus TCP Gateway
ZLAN5443A supports the function of Modbus TCP to Modbus RTU (Modbus Gateway
function). The Modbus Gateway supports reading data on multiple Modbus Client
connections, known as "multiple hosts".
Identify Gateway function: click "Device Manage" on the main interface of ZLVircom
software, search the device, select the device, and click "Edit Device". The parameter
settings dialog box that popup is shown as FIG. 6.
