The TM2500 and TM2700 are compact, rugged, industrial data entry and display terminals. They are intended for use as operator panels and as service/setup panels in microprocessor based equipment. The only difference between the two units is that the TM2500 has an RS-232-C communications interface, while the TM2700 has an RS-422 communications interface.

These units offer a large, 16-character liquid crystal display. The viewing angle may be operator adjusted electronically. The sealed keyboard consists of 24 keys, including a numeric keypad and six back-lit function keys. These units include an audible tone generator which may be used to provide a key “click,” and may be controlled by the host.

The TM2500/TM2700 offers two operating modes: character mode and block mode. In character mode, characters are transmitted as a key is depressed. In block mode, output messages are transmitted as a whole when the Enter key is pressed. Multidrop operation, in which a number of terminals are connected to the same RS-422 communications line, is possible with the TM2700 in block mode. Each terminal has a unique address for multidrop operation. Operating parameters, which can be selected, are viewing angle, mode, turnaround delay, baud rate, data format, handshaking, local echo, terminators, key click, key repeat, and cursor type. These selections are made during SETUP through the keyboard. Most can be controlled by downline host commands as well.
