Datasheet

R040 is a RS232 to WiFi 802.11b converter, also called „wireless terminal server“. This converter is a successor of the previous type M020. 
 
  • remote RS232 device to PC connection via a WiFi network 
  • bridge function – virtual RS232 channel in a WiFi network (between two R040) 
  • modem emulation - converters are connected using AT commands in a wireless network
 
The R040 module is able to connect a RS232 device to a PC over a wireless network. The Digi RealPort Software creates a virtual COM port on the host PC. This virtual port enables any software to communicate with a remote RS232 device. The COM port redirector runs under Microsoft Windows, UNIX and Linux. Maximum communication speed is 230400 bps.
 
The module parameters and functions are configured over SNMP or secured web communication (HTTP / HTTPS protocols). Power presence is indicated by a green LED close to the serial connector. The WiFi connector provides two LEDs: Link and Network activity. Small antenna (cca. 3 dB) is included.
 
A CANON 9M device connects through a nullmodem (“crossed”) serial cable with CANON 9F connector at both sides (“terminal-terminal” connection). A CANON 9F device connects through a modem (“straight”) serial cable with CANON 9M and CANON 9F connectors. All RS232 signals except for RING (1- DCD, 2 - RXD, 3 - TXD, 4 - DTR,  5 - GND, 6 - DSR, 7 - RTS a 8 - CTS) are transmitted. Usually only RXD, TXD and GND are used.
