There are two accessory ports on the back of the terminal footstand. Each
port supports one cartridge accessory. You cannot use two accessories

use two accessories that require a serial port connection at the same time.
The shape and size of the plug in the accessory cartridge prevents the
user from accidently connecting incompatible accessories.
To check the compatibility of accessories, see
