The five BNC IRIG\/pulse output BNC connectors can\nbe set for a wide range of pulse frequencies via internal\njumpers (see photo). The item ships with them set to IRIG-B\nAM. In addition, this unit has the Programmable Pulse\nOutput (PPO) option installed. The PPO output can be\nmapped to any of the five BNC pulse output connectors on the\nrear. The backlight is bright and even so the display is\nvery legible - see photos. The output from the console\nport obtained\nduring testing is copied below. The photos show the actual\nitem for sale. The clock shows the correct time and date and\nthe\ninternal 3.7V Lithium battery for maintaining settings has\njust been replaced with a fresh cell so you should be good for\nsome years to come. Full product details may be found in the\nUser Manual at\nhttps:\/\/www.prostudioconnection.net\/1311\/XL-AK_Manual.pdf.
