COM2 Serial Port INPUT / OUTPUT:
1 x D-SUB 9P Male connector with RS-422/RS-485 support. Fasten the cable to the connector using the
provided screws on the cable housing itself. Baud Rate Min: 50b/s, Max: 1497600b/s (1.5Mb/s), Non-isolated port.
Enhanced internal ESD Specifications: +/-15kV Human Body Model, +/-15kV IEC1000-4-2 Air Discharge,
+/-8kV I EC 1 000-4-2 Contact Discharge.
Communication modes: Communication mode is selected using Hatteland Display API (check Driver DVD and
review chapter: “HT B22 - API / VCOM Commands” in this manual for more information.
Port is connected as a 0-modem cable: DCD, DSR and DTR is connected together in port. RTS and CTS is
connected in port.
Master mode full duplex: Transmitter is always active (Using TX pins), Receiver is always active (Using RX pins),
RTS signal is ignored.
Slave mode half duplex:
If RTS is active then it will transmit data. If RTS is inactive then it will receive data. Echo is not supported. (You can not
receive your own transmitted data simultaneously). All communication occurs over RX pins.
Note: RX has logic to ensure that the computer detect stop bit if no logic are driving RX bus. (Open port or drivers are
disconnected). This ensures stable operation of the system.
1 x USB1.1 (<10m) and 3 x USB2.0 (<5m) INPUT / OUTPUT:
Supports USB compliant peripherals. Drivers for most USB devices are usually included in operating system or on
separate installation DVD’s delivered with Third Party products.
- Port 1 is by factory default locked to USB1.1 (<10m, 12Mbps) and the
1:1
symbol is indicated next to the connector.
Peripherals that require more or less than 12Mbps should not be connected to this port, as both driver and device
will fail to install and initalize correctly. Please re-connect your device into port 2,3,4 instead in these situations.
- Port 2,3,4 is USB2.0 (<5m, 480Mbps) compliant, including support for USB1.1 (<10m, 12Mbps) peripherals.
Network 1, 2 INPUT / OUTPUT:
Supports 10/100/1000Mbps Ethernet (LAN). Suitable for twisted pair cables CAT.5E. Make sure the network cable
connector ”clicks” into the RJ-45 connector.
