P800 Operating Manual

3 Remote Operation of P800
P800 may be controlled remotely through the RS232 port.
The unit is put into remote mode by a key sequence in local mode (see Section
2.7.4
). On
power down the mode of operation is remembered so it will power back up still in remote,
unless the self test fails.
To return to local, either issue the Z command or power up with the EXIT key pressed.
See also StagCom and/or Production Manager.
3.1 Remote Control Commands
Remote control commands are case insensitive, and so may be transmitted in either upper,
lower or mixed case. Spaces and tabs are ignored (The only exception to these rules is the
remote control `D' command).
In the following table, anything printed in UPPER CASE should be sent literally, while
anything in lower case represents a parameter which you should substitute with an
appropriate value. Some of the commands cause P800 to transmit information back to the
host, others do not.
P800's response is followed immediately by a carriage-return, linefeed, status-code (see
Section
3.2
), carriage-return, linefeed, prompt (a greater-than symbol).
S0 manufacturer device
Set the programmer for the specified manufacturer and
device. Each of the parameters consists of exactly three
hexadecimal characters.
S1 format
Set the I/O format. The parameter is a single ASCII
character, and may be one of the following:
4 (Intel hex); 5 (Motorola S-Record);
8 (Stag- hex); 9 (ASCII-hex-space); A (Stag Binary);
D (Binary); I (Intel 32).
Note that many of these formats may be illegal for a given
device. Additional formats may be added to this list by Stag
at a later date.
S3 security
Set the security flags.
The parameter is a hexadecimal number between 0 and
FFFFFFFF. Each bit corresponds to one security bit for the
currently selected device: bit 0 corresponds to fuse 0,
through to bit 31 corresponding to fuse 31.
Note that not all devices support security, and the number
of security fuses varies with the selected device.
S4
Fill the RAM between RAM-START and RAM-STOP with
the device's unprogrammed state.
SM bitmode
Set the bit-mode.
For 8-bit wide devices, legal combinations are: 010408 (8
bit gang); 020208 (8 bit 2of2), 040108 (8 bit 1of4), 010216
(16 bit gang), 020116 (16 bit 1of4), 010132 (32 bit gang).
