RS232 MODEM SUPPORT PROCEDURES

Modem Compatibility and The ML2430A Series Power Meter firmware supports Hayes-compatible mo- Commands dems. The commands used are as follows:

Command	Definition
+++	modem escape sequence
atz	reset modem to factory defaults
at&h1&r2x4v1q0f1s0=1e0	initialize modem for power meter use
atd”number”	dial “number”

Serial Interface This section presents an example of Autodial using a terminal emulator on a re-

Remote Operation mote computer ( \n = newline, \r = carriage return).

Example

1.Initialize local modem, using the same setup as the power meter:

at&h1&r2x4v1q0f1s0=1e0\r

&h1	transmit data flow control - use CTS
&r2	receive data flow control - use RTS
x4	full result code setting
v1	result codes in verbal mode
q0	result codes displayed
f1	local data echo OFF
s0=1	auto answer after 1 ring
e0	local command echo off

The modem should respond:

OK\n\r

2.Dial power meter:

atd<phone number>\r

When the modem finally connects to the power meter modem, the response will be:

CONNECT\n\r

There might be additional information after “CONNECT” but before the line termination characters.

3.The remote computer is now connected to the power meter. The power meter can now be asked to identify itself:

*IDN?\n

The response from an ML2438A operating in native mode will be:

RANRITSU,ML2438A,<serial number>,<firmware version>
