-- Welcome -- The MTSModemInstaller.mpkg software installer provides software for Multi-Tech's MultiModemUSB family of modems and related serial modems. Modems supported by this package include the MT9234ZBA, MT9234ZBA-USB, MT9234MU, MTCBA-C-x, MTCBA-G-x, and MTCBA-E-x. The MT9234ModemScripts.mpkg software installer provides software for Multi-Tech's MultiModemUSB family of CDC-ACM modems and related serial modems. Modems supported by this package include the MT9234ZBA, MT9234ZBA-USB, MT9234ZBA-USB-CDC, MT9234MU, and MT9234MU-CDC. The USB models (MT9234ZBA-USB, MT9234MU, MTCBA-C-U, MTCBA-G-U, and MTCBA-E-U) require a kernel extension (MultiModemUSB.kext) and the necessary modem scripts. The USB CDC-ACM models (MT9234ZBA-USB-CDC, MT9234MU-CDC) DO NOT require a kernel extension. They only require the necessary modem scripts. The serial models (MT9234ZBA, MTCBA-C, MTCBA-G, and MTCBA-E) require only the necessary modem scripts. NOTE 1: This software is Universal. The modem scripts and kernel extension contained in this installer are intended for Mac OS X 10.4 and newer running on a PowerPC Mac or Intel Mac. Multiple modems of the same model or differing models may be used at the same time on the same Mac. For USB models requiring the driver (MultiModemUSB.kext), the driver is currently only built for a 32-bit kernel. The driver will not load on a Mac OS X 10.6 system booted in 64-bit mode and thus the USB modem will not be found by the OS. NOTE 2: Some early models and some special builds of the MT9234ZBA-USB use the USB communication device class descriptor (0x02). These models will not work with some versions of Mac OS X (10.5 in particular). You may install the software, reboot, and then plug in the MT9234ZBA-USB. If the Power LED on the modem does not light up within 1 minute, then call Multi-Tech Systems for support. Normally the Power LED will light up within a few seconds of having the USB cable connected. -- Support Information -- Multi-Tech provides free technical support for your product.
