Modem

GTM-200M CR is a modem converter that bridges RS-232 or USB 2.0 hosts, such as PLCs and PCs, to a cellular link. It is supplied without a built-in modem, so you select a communication module to match the field requirements and the frequency bands in use.An integrated library handles the command set of the communication modules, so application developers can concentrate on their own software rather than vendor-specific commands. The unit supports standard AT commands, and SMS transmission and 3G/4G connection can be set up through the library.A metal, DIN-rail mountable housing and an isolated digital input for resetting the system suit installations in harsh environments. The unit operates from -25 ℃ to 70 ℃ and is supplied with drivers for Windows 10 x64 and Windows 11.ApplicationsWireless high-speed data transmission from serial or USB equipmentSMS-based alarm and command transmission3G/4G connection for remote industrial equipmentRemote system reset via digital input

GTM-205M CR is an M.2 to USB converter for engineers who need a cellular data link on a DIN rail. This variant ships without a built-in modem, so you install the communication module that matches the frequency bands used at your site. The unit connects to the host over a USB 3.1 Super Speed Plus interface.The converter responds to standard AT commands, and an integrated library is provided to simplify application development. It can be paired with a range of PLCs and PCs, with the library supporting SMS sending and 4G/5G connectivity, so development effort can focus on the application rather than on the command set of each module.A digital input channel, isolated to 3750 Vrms, can reset the system. The metal housing is rated for operating temperatures from -25 ℃ to 70 ℃ and is supplied with Windows 10 x64 and Windows 11 drivers.ApplicationsWireless high-speed data transferSMS messaging from PLCs and PCs4G/5G connectivity for remote industrial sites

GTM-205M-5GC CR is a DIN-rail mounted industrial 5G modem that lets PAC and PC applications send and receive data over cellular networks. It supports 5G SA/NSA bands as well as 4G and 3G global bands, so a single unit can be used where the local network type varies.Connectivity is provided through a USB 3.1 Super Speed Plus interface, with a single RS-232 port for a software-initiated system reset. The modem supports standard AT commands and can open TCP server, TCP client and UDP client connections over 5G or 4G. A digital input, isolated to 3750 Vrms, can be used to reset the system.This variant is the RoHS compliant version for China. The metal casing and an operating range of -25 ~ +70 °C suit cabinet installations where a compact cellular link is required.5G SA/NSA and 4G/3G global band supportUSB 3.1 Super Speed Plus interface, drivers for Windows 10 x64 and Windows 11TCP server, TCP client and UDP client connections over 5G/4GStandard AT command set for control and SMSIsolated digital input for system reset, 3750 VrmsMetal DIN-rail housing, 28 x 78.5 x 100 mmApplicationsRemote data transfer from PAC and PC applications over cellular networksSMS-based messaging from automation systemsCellular connectivity for distributed or remote industrial sites

The I-8213W-4GC CR is an industrial 4G LTE modem with integrated GPS, intended for moving data from remote instruments, meters, computers or control systems over cellular networks. It supports FDD LTE B1/B3/B8 and TDD LTE B38/B39/B40/B41, alongside WCDMA, GPRS and SMS.An integrated TCP/IP stack allows controllers with serial ports to reach the network without custom driver development. The module offers TCP Server, TCP Client and UDP Client connection modes over 4G, 3G or GPRS, and accepts standard AT commands.The -4GC variant is the TDD-capable version, labelled for China in the product description. Its sister model, the I-8213W-4GE, covers FDD LTE B1/B3/B5/B7/B8/B20 instead. The module installs on DIN-rail and is rated for -25 to 75 °C operation, and it pairs with WinPAC-8000, LinPAC-8000 or XP-8000 controllers.ApplicationsRemote data transfer from instruments, meters, computers or control systemsSMS, GPRS and 4G connections for PAC-based systemsLive or packet data transfer over cellular networks
