WARNING

Before you connect a voltage source, observe the following power supply voltage guidelines. Otherwise, you will void your warranty if the wrong voltage is applied.

Be sure the voltage source is within the permitted ranges shown above. Otherwise, your modem and any attached devices may be damaged.

Customer-supplied cables must be suitable for the site environmental conditions.

Screw terminals on the power interface accept 24 to 16 AWG. However, surge protection is guaranteed only if the ground wire is greater than 18 AWG and if there is a solidly earthed ground connection.

Be sure the power source is not controlled by a wall switch, which can be inadvertently turned off, shutting off power to the modem.

Connecting an RS-232 Device

The modem back panel provides a female, 25-pin RS-232 connector that accepts an attached RS-232 device (see Figure 2-1 on page 10). This connector accepts a standard connection to a DTE (RTU) that conforms to the pin assignments shown under “RS-232 (DTE) Interface” on page 38.
