XMODEM FIRMWARE UPDATES

Updating Firmware
To provide feature enhancements in the future, ATLAS 550 supports firm-
ware updating by field personnel. Two transfer methods are available for
use in updating any modules that contain Flash memory, including the AT-
LAS 550 system controller. The first transfer method is via the ATLAS 550
Control/Chain In port using XMODEM protocol. The second transfer meth-
od is via the ATLAS 550 built-in Ethernet port using TFTP (Trivial File
Transfer Protocol). To simplify the update procedure, a common menu in-
terface is available for updating any upgradable module within the ATLAS
550 (see also Update Firmware on page 6-17). The following sections describe
the procedure for updating using either transfer method.
Please consult the appropriate ATLAS 550 module manual to
determine if the module supports Flash upgrading.
Users must use the supplied connector when using VT-100 or
when doing any asynchronous Flash activity.
The ATLAS 550 supports firmware updating to any upgradable module us-
ing XMODEM transfer protocol via the base unit's Control/Chain In port.
XMODEM is found in most PC communications software packages. To con-
figure the Chain In port's data rate and other communication parameters,
consult Control/Chain In Port on page 2-4 and Control/Chain Out Port on page
2-5.
Ensure the communications software package being used has flow
control turned off.
