Issue
Upgrading Loytec L-IP to the latest firmware or checking current firmware version.
Environment
- Loytec L-IP
- Vista
- Network Interface
Cause
UL 864 v.9 for Smoke Control requires at least version 5.04 firmware in all system L-IP's.
Resolution
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:

(For UL 864 v9: If the Firmware Version does not reflect a Version 5.0.4 or Version 5.0.5, you must update the firmware to an approved version in the next steps. If the L-IP contains an approved version, further action is not required.)
L-IP Firmware Upgrade
- To download the firmware via the console connected the L-IP to the RS-232 port of a PC via its console interface as outlined above.
- Download the lswitch_lipxxx.zip located at www.loytec.com to the PC.
- Install the LOYTEC serial upgrade tool (LSU Tool) by double clicking LSU_2_0_1setup.exe.
- Double click on the lswitch_lip_xxx.dlc file. This will start the LSU Tool and load the firmware image referenced in the . lswitch_lip_xxx.dlc file. The start window of the LSU tool is shown in Figure 3.
*note that the lswitch_lip_xxx.dlc file and the lswitch_lip_xxx.dl file must be stored in the same folder.

- Exit the LSU Tool. Reconnect through HyperTerminal connection and initiate the console by a “enter” keystroke or power cycle of the L-IP. At the console main menu, select option [1] Show device information, and press Enter. This will bring up the current device information as shown in Figure 2, for verification that the firmware version has updated successfully.
