This section pertains to the following devices: TPP2, TPP3, TPP2(G2), and TPP3(G2). Obviously, this also covers TPS2, TPS3, TPS2(G2), and TPS3(G2).
TPS devices have TX and RX lines of their first serial port routed to socket S1. Plug Tibbit #01 (RS232) or #02 (RS232/422/485) into S1 (Tibbit #02 will also occupy S3). Plug Tibbit #19 (DB9M) into socket S2. Provide power, for example, by using a 12V power adapter and Tibbits #09 and #18. Use Tibbo's WAS-P0005(B) green serial cable to interconnect the DB9-M of Tibbit #19 and the COM port of your PC (or your USB-to-serial adapter):
