Upgrading Loytec L-IP to the latest firmware or checking current firmware version.
- Loytec L-IP
- Network Interface
UL 864 v.9 for Smoke Control requires at least version 5.04 firmware in all system L-IP's.
Verifying L-IP Firmware Version via Console Connection
To use the serial interface, the DB9 console connector of the L-IP can be connected to the RS-232 port of a PC. The L-IP-3ECTB and L-IP-33ECTB use a standard null-modem-cable must be used to connect the L-IP’s DB9console connector to the RS-232 port of the PC. The PC will communicate with the L-IP using a HyperTerminal program with the communication settings set to 38,400 bps / 8 data bits / no parity / 1 stop bit / no handshake.
The L-IP displays the console menu shown in Figure 1 upon a successful HyperTerminal connection initiated by a “enter” keystroke or power cycle of the L-IP:
