4.1. 48 Volt DC Power Option
The 48 Volt DC input is not polarity sensitive. Therefore, you can connect either positive or negative
wires from your 48 volt power source to either input and the internal circuitry will adjust for the proper
polarity.
Input Range: 40 - 60 Volts DC, 200 milliamps maximum.

5. Command Summary
● Type commands in either upper or lower case. Do not use a combination of upper and
lower case characters.
● Use the Backspace key to delete errors. Note that the original AT command is stored
in the modem buffer, and cannot be deleted.
● Some commands have numeric options. If these commands are invoked without a
numeric option, the modem will assume option 0 (zero). For example, when the
command ATBis invoked, the modem will assume command ATB0was intended.
● All commands begin with the AT prefix, and are invoked by pressing [Enter]
(Carriage Return). The only exceptions are the A/command (Repeat previous
command) and +++(Exit to on-line command mode).
● The maximum command length is 40 characters. This does not include the ATprefix,
Carriage Returns, or spaces.
Note: Default values are marked with an asterisk. All defaults are based on the
&F1-Hardware Flow Control Template loaded in NVRAM.
Command Function/Options

the AT prefix or a Carriage Return.
Any Key Aborts off-hook dial/answer operation and hangs up.
AT
Required prefix for all modem commands. Can also be used to test for the OK
result code. Not required for the A/ command or +++ command.

2
Sets the number of seconds the modem will wait before dialing. If Xn
is set to X2 or X4, S6 determines the timeout length when no dial tone
is detected.

used to select a longer duration when the modem is originating an
international connection.
S8
S9

Sets the duration (in seconds) for the Dial command pause option (,).
Determines the length of time (in tenths of a second) the remote
modem's carrier signal must continue in order to be recognized by the
RMM.
S10
7
Sets the length of time (in tenths of a second) the modem will wait
after loss of carrier before hanging up. Allows the modem to
distinguish between a line hit (or other momentary break) from a true
disconnect (hang up) by the remote modem.
Although it is not recommended to connect to a line with call waiting,
the S10 register can be adjusted upward to prevent the modem from
misinterpreting the second call signal as a remote disconnect. If call
waiting is a problem, it is preferable to contact your phone company to
determine the command to temporarily disable call waiting (typically
*70W). For example: ATDT *70W phone number.
Note: If S10 = 255, the modem will not hang up when the carrier is
lost. Dropping DTR hangs up the modem.
S11
S12
70
50
Sets the duration and spacing (in milliseconds) for tone dialing.
Sets the duration (in fiftieths of a second) of the guard time for the
escape code sequence (+++).
S13
0
Bit-mapped register. Select the bit(s) you want ON and set S13 to the
total of the values in the Value Column. For example, ATS13=17
enables bit 0 (value is 1) and bit 4 (value is 16).

* The 1.5K-byte non-ARQ buffer allows data transfer with Xmodem
and Ymodem type file transfer protocols without using flow control.
The 128 Byte option allows remote users with slower modems to
prevent transmitted data from scrolling off screen. When a remote user
sends an XOFF (Ctrl-S) to your computer and transmission stops, data
in transit from your modem's buffer does not exceed the size of the
remote user's screen. This is also helpful when a remote
modem/printer application is losing characters.

Sets an optional delay (in seconds) before a forced hang-up and
clearing of the Transmit buffer when DTR drops during an ARQ call.
This allows time for a remote modem to acknowledge receipt of all
transmitted data before it is disconnected.
When set at the default (0), the modem immediately hangs up when
DTR drops.
This option applies only to connections terminated by dropping DTR.
If the modem receives the ATH command, it ignores S38 and
immediately hangs up.
