Chapter Four: Communications
4.1 Communication Interfaces
There are two communication interfaces available for the TQ100 terminal:
9-pin RS232 interface and RJ45 interface, as illustrated in the Figure 4.1.
The RS232 interface provides RS232 communication, while the RJ45 interface
provides RS485 and Ethernet communication, see Figure 4.1 below.
RJ45 Interface
Attention:
1. Maximum communication distance of RS232 cable is 50 feet (15 m).
2. RS485 communication can connect multiple terminals
(up to 32 terminals) and the maximum communication distance
can reach 1000 feet (300 m). For optimal performance it is
recommended
to use up to 10 terminals in a RS485 network installation.
3. Ethernet communication mode belongs to Ethernet network connection.
It can be used to connect any terminals in the LAN.
4.2 Communication Options
Choose from three communication options:
1. Direct Connection using RS232 with RS232 communications.
2. RS485 network connection using RJ45 interface
3. Network Connection using Ethernet communication function
with RJ45 interface.
