Overview The MTD is a complex computer system that contains a radio, a processor, flash memory and RAM. The system is interacting with a cellular network while trying to talk to the host system it is connected to. Following these guidelines will help preserve the system in the best possible way. Related Documentation For more information re following documentation is available on the Multi-Tech Installation Resources website at www.multitech.com/setup/product.go.
Installing and Removing SIM Cards in an MTD-H5 Installing a SIM Card Only MTD-H5 models have a SIM card. Warning: If the device is connected to a computer or power supply, disconnect it. Inserting or removing a SIM card with the device powered may harm the SIM card and the device. 1. Remove the SIM cover from the back of the device. If you have trouble sliding the SIM cover, use a flat-blade screwdriver in the slot on the SIM cover to slide it out. 2.
Removing a SIM Card To remove a SIM card: Warning: If the device is connected to a computer or power supply, disconnect it. Inserting or removing a SIM card with the device powered may harm the SIM card and the device. Remove the SIM cover from the back of the device. If you have trouble sliding the SIM cover, use a flat-blade screwdriver in the slot on the SIM cover to slide it out. Slide the SIM card out. Replace the SIM cover.
Powering Devices On and Off Powering On the Device These devices are USB powered and do not have a power button. Note: Make sure the USB hub, whether external or internal, can provide adequate power. Max Peak current is in the range of 700mA for EV3 and 1.2A for H5. Refer to the device’s User Guide for more information. If the host system can’t provide enough power, then the 5V rail bounces, which causes the modem to lose power prematurely and could damage to the modem.
Basic Operations Preparing the Modem for a Data Connection Set the APN by issuing the following command where is the APN assigned by the carrier: AT+CGDCONT=1,”IP”,”” Check for registration by issuing AT+CREG? and wait for the response. If the second value of the response (for example, +CREG: x,y) is 1, then the modem is registered on the home network. If y=5, then the modem is registered but roaming. See the AT command reference guide for other possible responses.
Responding to Failed Connections When your device fails to connect Verizon recommends working through the steps below until your device connects: Wait 30 seconds and try again. Wait 1 minute and try again. Wait 2 minutes and try again. Wait 8 minutes and try again. Make one attempt every 15 minutes for an hour. Make one attempt every 90 minutes. When a call drops If a connected call drops for any reason: Wait 30 seconds and restart the sequence again.
Getting Help Several things can affect cellular modem service. Who you contact for help depends on what issue you are having: Contact the Cellular Carrier (SIM card provide for MTD-H5 models) for the following: Issues with account configuration. SIM card does not appear to be working. Cannot activate the radio. Radio appears to be activated, but you cannot get a data connection. (Verify that your account is configured for packet data.) Questions about data usage.

PRL Updates The Preferred Roaming List (PRL) is a database file that includes cell tower IDs and capabilities, a prioritized list of towers the device is allowed to connect to, and the preferred connection order. Consider updating your PRL if you have connection problems or if your carrier is updating cell towers in your area. PRL updates for Sprint and Verizon are over the air updates. To update your PRL, issue the following commands.
