L-IP Firmware Upgrade.

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

  1. 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.
  2. Download the lswitch_lipxxx.zip located at www.loytec.com to the PC.
  3. Install the LOYTEC serial upgrade tool (LSU Tool) by double clicking LSU_2_0_1setup.exe.
  4. 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.
